Du capteur à l’indicateur : les entrepôts de données spatiales au service d’une meilleure maîtrise des consommations énergétiques des entreprises agricoles
Innovations Agronomiques, 2017
abs web bib

Agricultural energy consumption is an important issue that concerns the international community for environmental and economic reasons. Technology of data warehouse and multidimensional database opens the door to new solutions for collect and decisional use of data. These technologies enable to have access, on collected and stored data, to a whole range of indicators resulting from aggregated operations (sum, mean) in function of different criteria (period of time, type of machine, type of work or management entity). In this project, integration chains of information from the sensor to the indicator have been developed for gas consumptions in mobile farm equipment (for cultures) and for electricity and water consumption in breeding buildings (cow and goat breeding) and for irrigation. The use of data collected thanks to the technological solutions implemented on the field, then their integration in the data warehouse in order to establish relevant indicators of the energetic consumption enables monitoring in real time and traceability of energy consumption at different scales of the farm, through dashboard instrument panel and diagnosis. This project has led to technological solutions to obtain reliable data, on a data warehouse able to integrate heterogeneous data in terms of quality and granularity at an accurate scale, in order to provide reliable performance indicators. / Les questions énergétiques liées aux exploitations agricoles constituent un sujet de recherche qui préoccupe la communauté internationale et ce, pour des questions environnementales et économiques. En matière de systèmes d'information, la technologie des entrepôts de données et les bases de données multidimensionnelles font émerger de nouvelles solutions pour le recueil et l'utilisation décisionnelle des données. Ces technologies permettent d'établir, sur des données collectées et archivées, toutes sortes d'indicateurs résultant d'opérations agrégées (somme, moyenne) en fonction de différents critères (période de temps, types de machines, types de travaux, entités de gestion, etc.). Elles permettent également des découvertes de relations causales et de classification de données. La faisabilité et l'intérêt de cette intégration de données ayant été démontrés dans le projet EnergéTIC, la poursuite des travaux a permis de déboucher sur des solutions techniques fiables pour une meilleure maîtrise des consommations énergétiques dans les exploitations agricoles, en utilisant un système d’information de type entrepôt de données spatiales qui puisse intégrer à une échelle fine des données hétérogènes de par leur niveau de qualité et de granularité.

Ce que l’épidémiosurveillance apporte ou n’apporte pas encore à la moindre dépendance aux produits phytopharmaceutiques
Innovations Agronomiques 59, 2017
abs web bib

Through different approaches, the teams gathered in the VESPA project shed light on different facets of the contribution of monitoring to crop protection. Values of information, referencing, pedagogy and maintenance of expert competences in phytopathology arise directly from its existence. Although the calculations are difficult and approximate, it is concluded that the monitoring benefits are at least 4 to 5 times more than it costs, including the authorisation of the reduction of pesticide use. However, these values mostly relate to the rational optimisation of the protection needs and they cannot only by themselves cover more than a quarter of the Ecophyto objectives of pesticide reduction. To go further, it becomes necessary that the warning messages modulate the risks of crop damages according to the prophylactic measures taken by farmers. / Par différentes approches (sémantique, économique, de modélisation), les équipes réunies dans le projet VESPA éclairent les différentes formes de contribution de l’épidémiosurveillance à la santé des cultures. Des valeurs d’information, de référencement, de pédagogie et d’entretien des compétences expertes en phytopathologie généraliste de terrain découlent assez directement de son existence. Bien que les calculs soient difficiles et entachés d’approximations, on conclut que l’épidémiosurveillance rapporte au minimum 4 à 5 fois plus qu’elle ne coûte, y compris en autorisant des réductions d’usage de produits phytopharmaceutiques. Ces apports relèvent toutefois majoritairement de l’optimisation rationnelle de la couverture des besoins de protection et elles ne peuvent à elles seules couvrir au mieux qu’une part des objectifs de réduction de la dépendance aux produits phytopharmaceutiques. Pour aller plus loin, il devient donc nécessaire que les messages d’alerte modulent le risque phytosanitaire en fonction des mesures prophylactiques prises et relaient l’efficacité d’une gamme élargie d’actions préventives.

A methodology for the publication of agricultural alert bulletins as LOD
Computers and Electronics in Agriculture, 2017
abs doi web bib

In this paper, we present our Semantic Web system for the storage of 19,448 agricultural alert bulletins in France. The archive of alert bulletins was published on the Web as Linked Open Data (LOD). LOD uses Semantic Web technologies to publish data on the Web. Some best practices for publishing Linked Data are already proposed. We enrich these best practices in order to meet some specific information retrieval needs: spatiotemporal and thematic annotations and aggregation indicators. We illustrate our proposal by the publication of our archive. We describe our methodology for building the system and highlight the interest regarding Semantic Web technologies for this agricultural alert storage, publication and analysis. To prove that our system answers our needs, we propose some queries to illustrate the calculation of spatiotemporal aggregation indicators.

GECO, the French Web-based application for knowledge management in agroecology
Computers and Electronics in Agriculture, 2017
abs doi web bib

This paper proposes new approaches to the management and transfer of knowledge in agroecology, utilizing methodological tools developed by the French knowledge management group in the field of agroecology. These tools are based on the transfer of explicit and tacit knowledge within organizations. We apply one of these tools to help better determine the best knowledge transfer method to implement. We also propose a collaborative Web-based application, Agro-PEPS as the prototype and GECO as the final application (geco.ecophytopic.fr), to facilitate knowledge transfer in agriculture. AgroPEPS and GECO allow users to formalize knowledge in a collaborative manner and to make it available to a large community. These tools are based on semantic models related to agroecolog

Current approaches, challenges and perspectives on Spatial OLAP for agri-environmental analysis
International Journal of Agricultural and Environmental Information Systems IJAEIS 7 (1), 2016
abs doi web bib

Spatial OLAP (SOLAP) systems are powerful GeoBusiness Intelligence tools for analysing massive volumes of geo-referenced datasets. Therefore, these technologies are receiving considerable attention in the research community and in the database industry as well. Applications of these technologies are current in several domains such as ad marketing, healthcare, and urban development, to name a few. Contrary to other application domains, in the context of agri-environmental data and analysis, SOLAP systems have been underexploited. Therefore, in this paper, we make an exhaustive survey of most of the published studies in the domain of the SOLAP analysis of agri-environmental data with an emphasis on the reasons why only few recent works investigate the use of SOLAP systems in the agri-environmental context. In particular, we focus on the complexity of the spatiomultidimensional model and its implementation. Moreover, based on surveying the state of the art in this domain, this paper identifies some general guidelines that must be considered by the scientific community to design and implement efficient SOLAP approaches to the analysis of geo-referenced agri-environmental datasets. Finally, open issues about warehousing and OLAPing agri-environmental data are also shown in the paper

A system for the rapid design and implementation of personalized agricultural key performance indicators issued from sensor data
Computers and Electronics in Agriculture 130, 2016
abs doi web bib

Farm Management Information Systems provide decision-makers (farmers) with a set of predefined Key Performance Indicators (KPIs) that are issued manually from collected data or via sensors installed on farm equipment. However, agricultural decision-makers need ad-hoc KPIs issued from low-cost sensors. Therefore, we present our VBoxReporting system in this paper. VBoxReporting is a complete system that allows the rapid design and implementation of reporting KPIs issued from VBox data. VBox, which was developed by Exotic Systems, is a low-cost sensor for tracing the energy use of agricultural equipment. Once the indicators are modeled, VBoxReporting automatically generates all of the scripts required to load data from VBox and create the indicators. We also provide a usability study to validate our user interface layer.

Cohérence logique dans les systèmes OLAP spatiaux : un état de l’art
International Journal of Geomatics and Spatial Analysis-Revue Internationale de Géomatique 26 (1), 2016
abs doi web bib

Les systèmes d'Entrepôts de Données et « OnLine Analytical Process » spatiaux (EDS et SOLAP) sont des technologies d'aide à la décision permettant l’agrégation et l'analyse multidimensionnelle de gros volumes de données spatiales. En réponse à des actions utilisateurs sur l'interface cliente (exploration), les systèmes SOLAP agrègent les données de l'EDS le long de différentes hiérarchies des dimensions pour calculer des indicateurs d'analyse à différents niveaux de détails. La qualité des indicateurs d'analyse dépend donc de trois facteurs : la qualité des données entreposées, la qualité des agrégations et la qualité de l’exploration des données. La qualité des données entreposées dépend de critères comme la précision, l'exhaustivité et la cohérence logique. La cohérence logique des données est généralement contrôlée par les contraintes d'intégrité qui définissent les conditions que les données doivent satisfaire. La qualité d'agrégation peut être ramenée à la cohérence logique entre les natures des éléments qui sont impliqués dans l'agrégation SOLAP (par ex., mesure, fonction d'agrégation). Cette cohérence d'agrégation est affectée par des problèmes structurels et de problèmes sémantiques. La qualité d'exploration dépend essentiellement de la consistance des requêtes utilisateur (par ex. quelles ont été les valeurs de température en URSS en 2010 ?). Dans cette article nous étendons la notion de cohérence logique des données aux deux autres composantes fondamentales des systèmes SOLAP, à savoir l'agrégation et la requête. Nous présentons un état de l'art et des travaux sur la définition des contraintes d’intégrité pour garantir la cohérence logique au niveau des trois composantes (données, agrégations, et requêtes), ainsi qu' une évaluation de ces travaux et de notre proposition par rapport à un ensemble de critères que nous avons définis. Cette évaluation montre que notre proposition satisfait tous les critères contrairement aux autres.

Evaluation of user satisfaction with OLAP recommender systems: An application to RecoOLAP on a agricultural energetic consumption datawarehouse
Int. J. Business Information Systems 21 (1), 2016
abs web bib

OLAP and datawarehouse (DW) systems are technologies intended to support the decision-making process, enabling the analysis of a substantial volume of data. One of the goals of recommender systems is to help users navigate large amounts of data. OLAP recommender systems have recently been proposed in the literature because the multidimensional analysis process is often tedious because the user may not know what the forthcoming query should be. User satisfaction with these systems has not yet been investigated. Thus, this work is the first study of the usefulness of OLAP recommender systems from the decision maker’s point of view. Indeed, to the best of our knowledge, although several works have proposed OLAP recommender systems, they did not evaluate them against real-world data and users.

Business intelligence indicators: Types, models and implementation
International Journal of Data Warehousing and Mining 12 (4), 2016
abs web bib

Nowadays, more and more data are available for decisional analysis and decision-making based on different indicators. Although different decision-making technologies have been developed, we note the lack of a conceptual framework for the definition and implementation of these indicators. In this paper, we propose a first classification of these indicators. Furthermore, motivated by the need for formalism for the definition of these indicators at a conceptual level, we present the Business Intelligence Indicators (BI2) UML profile to represent indicators for OLAP, OLTP and streaming technologies. We also present their implementation in existing industrial tools. In addition, we show how these indicators can coexist in the same environment to exchange data through a chaining model and its implementation.

A framework for spatio-multidimensional analysis improved by chorems: Application to agricultural data
Lecture Notes in Business Information Processing, 2016
abs web bib

Spatial OLAP (SOLAP) systems are decision-support systems for the analysis of huge volumes of spatial data. Usually, SOLAP clients provide decision-makers with a set of graphical, tabular and cartographic displays to visualize warehoused spatial data. Geovisualization methods coupled with existing SOLAP systems are limited to interactive (multi) maps. However, a new kind of geovisualization method recently appears to provide summaries of geographic phenomena: the chorem-based methods. A chorem is theoretically defined as a schematized spatial representation, which eliminates any unnecessary details to the map comprehension. Therefore, in this paper we investigate the opportunity to integrate SOLAP and chorem systems in a unique decision support system.

However, a new kind of geovisualization method recently appears to provide summaries of geographic phenomena: the chorem-based methods.

Intelligent flood adaptive context-aware system: How wireless sensors adapt their configuration based on environmental phenomenon events
Sensors and Transducers 206 (11), 2016
abs web bib

Henceforth, new generations of Wireless Sensor Networks (WSN) have to be able to adapt their behavior to collect, from the study phenomenon, quality data for long periods of time. We have thus proposed a new formalization for the design and the implementation of context-aware systems relying on a WSN for the data collection. To illustrate this proposal, we also present an environmental use case: the study of flood events in a watershed. In this paper, we detail the simulation tool that we have developed in order to implement our model. We simulate several scenarios of context-aware systems to monitor a watershed. The data used for the simulation are the observation data of the French Orgeval watershed.

Conceptual model for spatial data cubes: A UML profile and its automatic implementation
Computer Standards & Interfaces 38, 2015
abs doi web bib

The increasing availability of geo-referenced data has increased the need to enrich OLAP with spatial analysis, leading to the concept of Spatial OLAP (SOLAP). The conceptual modelling of spatial data cubes requires the definition of two kinds of metadata: (i) warehouse metadata that model data structures that maintain integrated data from multiple data sources and (ii) aggregation1 metadata that specify how the warehoused data should be aggregated to meet the analysis goals of decision makers. In this paper we provide a review of existing conceptual spatial data cube models. We highlight some limits of these models concerning the aggregation model design, and their implementation in existing CASE tools and SOLAP architectures. Firstly, we propose a new UML (Unified Modeling Language) profile for modelling complex Spatial Data Warehouses and aggregations. Our profile is implemented in the MagicDraw CASE tool. Secondly, we propose a tool for the automatic implementation of conceptual spatial data cube models, designed using our profile, in a SOLAP architecture. In particular, our solution allows: (i) generating different logical representations of the SDW (Spatial Data Warehouse) model (star schema and snow-flake schema) and (ii) implementing complex SOLAP analysis indicators using MDX (MultiDimensional eXpressions language).

A Scalable Context-Aware Objective Function (SCAOF) of Routing Protocol for Agricultural Low-Power and Lossy Networks (RPAL)
Sensors 15 (8), 2015
abs doi web bib

In recent years, IoT (Internet of Things) technologies have seen great advances, particularly, the IPv6 Routing Protocol for Low-power and Lossy Networks (RPL), which provides a powerful and flexible routing framework that can be applied in a variety of application scenarios. In this context, as an important role of IoT, Wireless Sensor Networks (WSNs) can utilize RPL to design efficient routing protocols for a specific application to increase the ubiquity of networks with resource-constrained WSN nodes that are low-cost and easy to deploy. In this article, our work starts with the description of Agricultural Low-power and Lossy Networks (A-LLNs) complying with the LLN framework, and to clarify the requirements of this application-oriented routing solution. After a brief review of existing optimization techniques for RPL, our contribution is dedicated to a Scalable Context-Aware Objective Function (SCAOF) that can adapt RPL to the environmental monitoring of A-LLNs, through combining energy-aware, reliability-aware, robustness-aware and resource-aware contexts according to the composite routing metrics approach. The correct behavior of this enhanced RPL version (RPAL) was verified by performance evaluations on both simulation and field tests. The obtained experimental results confirm that SCAOF can deliver the desired advantages on network lifetime extension, and high reliability and efficiency in different simulation scenarios and hardware testbeds.

New design approach to handle spatial vagueness in Spatial OLAP datacubes: Application to agri-environmental data

Spatial-OLAP (SOLAP) technologies are dedicated to multidimensional analysis of large volumes of (spatial) data. Spatial data are subject to different types of uncertainty, in particular spatial vagueness. Although several researches propose new models to cope with spatial vagueness, their integration in SOLAP systems is still in an embryonic state. Also, analyzing multidimensional data with metadata brought by the exploitation of the new models can be too complex and demanding for decision-makers. To help reduce spatial vagueness consequences on the exactness of SOLAP analysis queries, we present a new approach for designing SOLAP datacubes based on end-users' tolerance to the risks of misinterpretation of fact data. An experimentation of the new approach on agri-environmental data is also proposed

Spatial Data Warehouses (SDWs) and Spatial On-Line Analytical Processing (SOLAP) systems are new technologies for the integration and the analysis of huge volume of data with spatial reference. Spatial vagueness is often neglected in these types of systems and the data and analysis results are considered reliable. In a previous work, we provided a new design method for SOLAP datacubes that allows the handling of vague spatial data analysis issues. The method consists of tailoring SOLAP datacubes schemas to end-users tolerance levels to identified potential risks of misinterpretation they encounter when exploiting datacubes containing vague spatial data. It this paper, we further our previous proposal by presenting different formal tools to support our method: It is an UML profile providing stereotypes needed to add vague, risks and tolerance levels information on datacubes schemas plus the formal definition of SOLAP datacubes schemas transformation process and functions.

Effect of digested sludge properties on mechanical dewatering efficiency: An experimental approach
Drying Technology 33 (11), 2015
abs doi web bib

To optimize the anaerobic digestion process of residual sludge, co-substrates addition and pre-treatments are increasingly being employed. Nevertheless, if these processes allow the optimization of biogas production, they can significantly impact the efficiency of mechanical dewatering processes for digested sludge. In this article, the impact of co-substrate addition (oily sludge) and thermal pre-treatment on the efficiency of mechanical dewatering of digested sludge was investigated. To this purpose, mechanical dewatering experiments were conducted at lab-scale by using a filtration-compression cell to determine the limit dryness of various digestates. In addition, control factors of the mechanical dewatering efficiency of digested sludge were investigated. Results highlight that 67% of the variance of the limit dryness of digestates is due to the variable 'volatile solid/total solid ratio

AgroPEPS is a collaborative web tool of knowledge management focused on agro-ecology, designed for and with future and potential users of the Joint technology network for ‘innovative cropping system’.Its aims are to capitalize knowledge and experiences in order to allow several actors in agriculture to design, pilot, manage and train innovative cropping systems, which are performant economically, environmentally and socially. Nowadays, developed as a prototype, Agro-PEPS makes available 150 techniques, described and structured according to 5 issues of sustainable development (water, air, soil, fossil resources, biodiversity). To reach them, Agro-PEPS has functionalities of syntactic research by keywords and of semantic research allowing a better targeting. This tool concept finds a favorable echo in the French R&D and training system: we recorded in January 2015 about 240 000 connections on the web site since its start which was confidential due to its prototype status. However its evolution in an operational web tool remains to be formalized. / AgroPEPS est un outil web collaboratif de gestion des connaissances dédié à l’agroécologie, conçu pour et avec les futurs utilisateurs dans le cadre du RMT Systèmes de culture innovants. Il a pour objectifs de capitaliser les connaissances et expériences disponibles afin de permettre à différents acteurs du monde agricole de concevoir, piloter, gérer et faire l’apprentissage de systèmes de culture innovants et performants d’un point de vue économique, environnemental et social. Aujourd’hui développé sous forme de prototype il met a disposition des utilisateurs 150 techniques, décrites et structurées en fonction de cinq enjeux de développement durable (l’eau, l’air, le sol, les ressources fossiles et la biodiversité). Pour y accéder, AgroPEPS dispose de fonctionnalités de recherche syntaxique classique par moteur de recherche et de fonctionnalités de recherche sémantique permettant un meilleur ciblage. Ce concept d’outil trouve un écho très favorable dans le monde du développement, de la recherche et de la formation : on dénombre fin janvier 2015 près de 240.000 connexions au site depuis sa mise en ligne pourtant restée "confidentielle" compte-tenu du caractère de prototype de l’outil.

Performance optimization of grid aggregation in spatial data warehouses
International Journal of Digital Earth 8 (12), 2015
abs doi web bib

The problem of storage and querying of large volumes of spatial grids is an issue to solve. In this paper, we propose a method to optimize queries to aggregate raster grids stored in databases. In our approach, we propose to estimate the exact result rather than calculate the exact result. This approach reduces query execution time. One advantage of our method is that it does not require implementing or modifying functionalities of database management systems. Our approach is based on a new data structure and a specific model of SQL queries. Our work is applied here to relational data warehouses.

Energy-network performance trade-off in a slotted IEEE 802.15.4 network with acknowledged uplink transmissions
International Journal of Sensor Networks 17 (4), 2015
abs doi web bib

This paper provides an analysis of the performance of wireless sensor network (WSN) under the beacon-enabled slotted CSMA/CA of IEEE 802.15.4 Standard in non-saturation mode with acknowledged uplink and limited buffers. The performance metrics of a node considered are: Reliability, average throughput per node, average packet delay and average energy consumption. An analytical model of energy is derived and used to analyse the average consumption of node. This model takes into account energy dissipation of the radio unit and also of the processing and the sensor units. All these performance metrics are evaluated with different parameters such as medium access control (MAC) parameters, network density and offer load per node in order to observe their influence and adjust them if necessary to obtain good performance.

Towards the use of probabilistic spatial relation databases in business process modeling
International Journal of Agricultural and Environmental Information Systems IJAEIS 6 (3), 2015
abs doi web bib

In this paper, the authors combine the methods of probabilistic databases, GIS (Geographical Information Systems) and business process modelling to evaluate the agricultural activities. The authors provide a technique to evaluate the risk of agricultural activities among the hydrological objects (lakes, rivers, etc.) and agricultural plots. The spatial relation is an important information needed in the evaluation processes. This type of information is usually uncertain and the available data are often not precise. Consequently, probabilistic database is used to capture the uncertainty of the spatial objects in order to estimate the level of possible water and soil contamination (by agricultural inputs). Probabilistic spatial relations provide information on the layout of spatial objects. Probabilities are stored in a probabilistic database. Probabilistic database is a finite number of complete databases that are assigned with a set of probabilities. Probabilistic data-aware business processes integrate the theory of probabilistic database with business processes modeling methods. This new formalism of business processes helps the experts to model the environmental risks in terms of probabilistic spatial relations

Dynamic path tracking control of a vehicle on slippery terrain
Control Engineering Practice 42, Elsevier Ltd, 2015
abs doi web bib

This paper deals with accuracy and reliability for the path tracking control of a four wheel mobile robot with a double-steering system when moving at high dynamics on a slippery surface. An extended kinematic model of the robot is developed considering the effects of wheel-ground skidding. This bicycle type model is augmented to form a dynamic model that considers an actuation of the four wheels. Based on the extended kinematic model, an adaptive and predictive controller for the path tracking is developed to drive the wheels front and rear steering angles. The resulting control law is combined with a stabilization algorithm of the yaw motion which modulates the actuation torque of each four wheels, on the basis of the robot dynamic model. The global control architecture is experimentally evaluated on a wet grass slippery terrain, with speeds up to 7. m/s. Experimental results demonstrate enhancement of tracking performances in terms of stability and accuracy relative to the kinematic control. Highlights: Extended kinematic and dynamic models of a double-steered vehicle are proposed. A new adaptation dynamic sideslip observer considers the lateral slope. An adaptive and predictive double steering controller is developed. A stabilizer of the yaw motion modulates the actuation torque of each four wheels. Experiments are performed on a wet grass slippery terrain, with speeds up to 7m/s.

Dimension enrichment with factual data during the design of multidimensional models: application to bird biodiversity
Lecture Notes in Business Information Processing 241, 2015

Data warehouses (DW) and OLAP systems are technologies allowing the on-line analysis of huge volume of data according to decision-makers' needs. Designing DW involves taking into account functional requirements and data sources (mixed design methodology). But, for complex applications, existing automatic design methodologies seem inecient. In some cases, decisionmakers need querying, as a dimension, data which have been defined as facts by actual automatic mixed approachs. Therefore, in this paper, we offer a new mixed renement methodology relevant to constellation multidimensional schema. The proposed methodolgy allows to decisionmakers to enrich a dimension with factual data. In order to validate our theoretical proposals, we have implemented an enrichment tool and we have tested it on a real case study from bird biodiversity

Stakeholders involvement on establishing public-private partnerships through innovation in agricultural mechanization: A case study
International Journal of Agricultural Management 4 (2), 2015
abs doi web bib

Agricultural production has to increase drastically for the next years in order to meet societies’ needs. At the same time, using sustainable ways to produce this huge amount of food and resources is becoming increasingly critical. Innovation, both in technologies and in uses/ practices, is strongly encouraged in Europe as a solution to these challenges. As this process remains very complex to manage, analysing it in real conditions seems crucial, especially to improve it. Then, in this paper, we will present and analyse an experimental Public-Private Partnerships Action launched at the European level. This one-year action aimed to gather together all the players involved at the European level for crop protection and to boost concrete innovation in ICT (Information and communication technology) to reduce the use of pesticides, especially around three types of technologies using ICT and robotics. For small and medium-sized enterprises, the particular area of agricultural machinery, solutions have to be found to offset the necessary confidentiality of private stakeholders’ interests, and also to give them some reassurance, or at least advantages, on the results of such partnerships.

A new Spatial OLAP approach for the analysis of volunteered geographic information
Computers Environment and Urban Systems 48, 2014
abs doi web bib

Volunteered Geographic Information (VGI) has great potential for enhancing analysts’ capabilities, assuming that VGI data quality issues, such as credibility and precision, are properly addressed. In this paper, we study the integration of VGI in Spatial OLAP (SOLAP) systems, which allow the integration and analysis of large volumes of good quality data. Using a real-world scenario, we highlight some similarities and differences among these two types of systems. We define a conceptual quality-oriented framework for warehousing and OLAPing VGI data. In particular, to address precision and credibility problems related to VGI data, we propose two new ETL operators: aggregation based on the VGI credibility and a filter based on the historical precision. We also define a new spatio-multidimensional model that provides decision makers with a global description of the quality of the aggregated data. To validate our proposal, we extend the classical relational SOLAP architecture using a standard VGI system.

Special section on "Spatial data warehouses and SOLAP"
Geoinformatica 18 (2), 2014
abs doi web bib

Data Warehouses (DW) and OnLine Analytical Processing (OLAP) tools are used in Business Intelligence (BI) applications in order to support decision-making processes. DWs are a specific type of database used to integrate, accumulate and analyze data from various sources. OLAP tools provide means to query and to analyze the warehoused information and produce online statistical summaries (indicators) at different levels of details. These indicators are computed using aggregate functions (e.g. Sum, Avg, Min, Max, etc.). Users can explore DWs by performing OLAP operations (e.g., Roll-up, Drill-down, etc.). Data mining algorithms can also be used in DWs, aiming towards improving data analysis; these techniques help to discern automatically the correlations and causal links between data. The increasing availability of geo-referenced data has made necessary the need to enrich OLAP with spatial analysis tools.

A new sensor-based Spatial OLAP architecture centered on an agricultural farm energy-use diagnosis
International Journal of Decision Support System Technology 5 (4), 2014
abs web bib

Agricultural energy consumption is an important environmental and social issue. Several diagnosis tools have been proposed to define indicators for analyzing the large-scale energy consumption of agricultural farm activities (year, farm, production activity, etc.). In Bimonte, Boulil, Chanet and Pradel (2012), the authors define (i) new appropriate indicators to analyze agricultural farm energy-use performance on a detailed scale and (ii) show how Spatial Data Warehouse (SDW) and Spatial OnLine Analytical Processing (SOLAP) GeoBusiness Intelligence (GeoBI) technologies can be used to represent, store, and analyze these indicators by simultaneously producing graphical and cartographic reports. These GeoBI technologies allow for the analysis of huge volumes of georeferenced data by providing aggregated numerical values visualized by means of interactive tabular, graphical, and cartographic displays. However, existing data collection systems based on sensors are not well adapted for agricultural data. In this paper, the authors show the global architecture of our GeoBI solution and highlight the data collection process based on agricultural ad hoc sensor networks, the associated transformation and cleaning operations performed by means of Spatial Extract Transform Load (ETL) tools, and a new implementation of the system using a web-services-based loosely coupled SOLAP architecture to provide interoperability and reusability of the complex multi-tier GeoBI architecture. Moreover, the authors detail how the energy-use diagnosis tool proposed in Bimonte, Boulil, Chanet and Pradel (2012) theoretically fits with the sensor data and the SOLAP approach.

Analyse des indicateurs énergétiques des entreprises agricoles : une approche spatial OLAP

abs doi web bib

Spatial data warehouses and Spatial OLAP systems are business solutions that can be used for environmental applications. Indeed, in order to better assess the impacts of human activities on the environment, many spatio-temporal data should be collected in order to calculate indicators at different levels of aggregation. Spatial OLAP tools are well adapted to analyze these indicators in a multi-dimensional way for identifying and implementing policies to improve practices in order to minimize impacts. In this study, we focus on farms energy consumption in order to identify the tasks and work environments that consume the most energy. We show how SOLAP tools can be used for the spatio-multidimensional analysis of these indicators, and the research issues related to agricultural data warehousing and analysis process.

OLAPing Field Data: A theoretical and implementation framework
Fundamenta Informaticae 131, 2014

Integration of spatial data into multidimensional models leads to the concept of Spatial OLAP (SOLAP). Usually, SOLAP models exploit discrete spatial data. Few works integrate continuous field data into dimensions and measures. In this paper, we provide a formal multidimensional model that supports measures and dimension as continuous field data, independently of their implementation. We provide also a proposal for a logical model allowing aggregation of field measures in a feasible ROLAP architecture.

A generic geovisualization model for spatial OLAP and its implementation in a standards-based architecture
Ingénierie des Systèmes d'Information, 2014
abs doi web bib

Spatial Data Warehouse (SDW) and Spatial On-Line Analytical Processing (SOLAP) systems are technologies intended to support geographic business intelligence. SOLAP clients provide a cartographic representation of facts on maps, and perform SOLAP operations through simple user interactions with the maps. Services are unassociated, loosely coupled units of functionality that are self-contained. A Service Oriented Architecture (SOA) is an architectural design pattern where each tier is defined by means of a set of web services. (Un)luckly, there is currently no standard approach to implement SOA solution for visualizing the results of SOLAP queries. Existing SOLAP clients are not flexible and provide closed ad-hoc implementation policies for the visualization of SOLAP queries, which is an important obstacle to interoperability. In this paper we propose a data model for the cartographic visualization of SOLAP queries. Based on this model, we present a new SOA architecture for SOLAP systems where the SOLAP client is totally based on standard data representations (e.g. XMLA, SLD, etc.), and cartographic visualization web services (XMLA, WMS, etc.).

A generic Spatial OLAP model for evaluating natural hazards in a volunteered geographic information context

Spatial data warehouses (SDW) and spatial OLAP (SOLAP) systems are well-known business intelligence technologies that aim to support a multidimensional and online analysis for a large volume of geo-referenced datasets. SOLAP systems are already used in the context of natural hazards for analyzing sensor data and experts’ measurements. Recently, new data gathering tools coined as volunteered geographic information systems (VGI) have been adopted especially by non-expert users. Hence, (spatial) application development is facing a new challenge, which is the integration of expert-oriented data with citizen-provided data. In this paper, we propose a new generic spatio-multidimensional model based on the question/answer risk evaluation model that allows the integration of VGI data with classical SDW and SOLAP systems for the online analysis of natural hazards monitored by volunteers.

Spatial OLAP integrity constraints: From UML-Based specification to automatic implementation: Application to energetic data in agriculture
Journal of Decision Systems 23 (4), 2014
abs doi web bib

Spatial OLAP systems are Business Intelligence technologies allowing efficient and interactive analysis of large spatial data cubes. In this type of systems the correctness of analysis depends on: The warehoused data quality, how aggregations are performed and how data cubes are explored. In this paper we study quality control techniques (based on integrity constraints) related to exploration of spatial data cubes. We extend our UML framework previously proposed with a UML profile allowing the conceptual design of several classes of exploration integrity constraints. We also propose a tool for their automatic implementation. We validate our proposal in the context of a real case study concerning the analysis of energetic farm energetic indicators.

Multidimensional modeling and analysis of large and complex watercourse data: An OLAP-based solution
Ecological Informatics 24, 2014
abs doi web bib

This paper presents the application of Data Warehouse (DW) and On-Line Analytical Processing (OLAP) technologies to the field of water quality assessment. The European Water Framework Directive (DCE, 2000) underlined the necessity of having operational tools to help in the interpretation of the complex and abundant information regarding running waters and their functioning. Several studies have exemplified the interest in DWs for integrating large volumes of data and in OLAP tools for data exploration and analysis. Based on free software tools, we propose an extensible relational OLAP system for the analysis of physicochemical and hydrobiological watercourse data. This system includes: (i) two data cubes; (ii) an Extract, Transform and Load (ETL) tool for data integration; and (iii) tools for OLAP exploration. Many examples of OLAP analysis (thematic, temporal, spatiotemporal, and multiscale) are provided. We have extended an existing framework with complex aggregate functions that are used to define complex analysis indicators. Additional analysis dimensions are also introduced to allow their calculation and also for purposes of rendering information. Finally, we propose two strategies to address the problem of summarizing heterogeneous measurement units by: (i) transforming source data at the ETL tier, and (ii) introducing an additional analysis dimension at the OLAP server tier.

Spatial Data Warehouses (SDW) and Spatial OLAP (SOLAP) are well-known Business Intelligence (BI) technologies that aim to support multidimensional and online analysis of huge volumes of data with spatial reference. Spatial vagueness is one of the most neglected imperfections of spatial data. Although several works propose new adhoc models for handling spatial vagueness, their implementation in Spatial Database Management Systems (DBMS) and SDW is still in an embryonic state. In this paper, we present a new design method for SOLAP datacubes that allows handling vague spatial data analysis issues. This method relies on a risk management method applied to the potential risks of data misinterpretation and decision-makers’ tolerance levels to those risks. We also present a tool implementing our method and a validation of the method is done based on the designed datacubes schemas testing.

Cost models for selecting materialized views in public clouds
International Journal of Data Warehousing and Mining 4 (1), 2014
abs web bib

Data warehouse performance is usually achieved through physical data structures such as indexes or materialized views. In this context, cost models can help select a relevant set of such performance optimization structures. Nevertheless, selection becomes more complex in the cloud. The criterion to optimize is indeed at least two-dimensional, with monetary cost balancing overall query response time. This paper introduces new cost models that fit into the pay-as-you-go paradigm of cloud computing. Based on these cost models, an optimization problem is defined to discover, among candidate views, those to be materialized to minimize both the overall cost of using and maintaining the database in a public cloud and the total response time of a given query workload. We experimentally show that maintaining materialized views is always advantageous, both in terms of performance and cost.

Domain-Specific Modeling for a Crop Model Factory
International Journal of Agricultural and Environmental Information Systems IJAEIS 4 (2), 2013
abs doi web bib

In the context of crop model design for industrial purposes, this paper proposes a domain-specific modeling approach to provide a crop model factory for the modelers in agronomy. The authors’ approach proposes to separate the concerns of representing the simulation process (process-based dynamics) and the plant data structure. They propose a refined and stabilized metamodel for the dynamics based on past preliminary work. This paper also explains how the Model-View-Controller design pattern can be applied to DSML environments to produce a more specialist-friendly interface. In addition, the authors propose a metamodeling usage of the Model-View-Controller offering the potential to develop a DSML for DSMLs design.

Guaranteeing the quality of multidimensional analysis in data warehouses of simulation results: application to pesticide transfer data produced by the MACRO Model
Ecological Informatics 16, 2013
abs web bib

Currently, the vital impact of environmental pollution on economic, social and health dimensions has been recognized. The need for theoretical and implementation frameworks for the acquisition, modeling and analysis of environmental data as well as tools to conceive and validate scenarios is becoming increasingly important. For these reasons, different environmental simulation models have been developed. Researchers and stakeholders need efficient tools to store, display, compare and analyze data that are produced by simulation models. One common way to manage simulation results is to use text files; however, text files make it difficult to explore the data. Spreadsheet tools (e.g., OpenOffice, MS Excel) can help to display and analyze model results, but they are not suitable for very large volumes of information. Recently, some studies have shown the feasibility of using Data Warehouse (DW) and On-Line Analytical Processing (OLAP) technologies to store model results and to facilitate model visualization, analysis and comparisons. These technologies allow model users to easily produce graphical reports and charts. In this paper, we address the analysis of pesticide transfer simulation results by warehousing and OLAPing data, for which the data results from the MACRO simulation model. This model simulates hydrological transfers of pesticides at the plot scale. We demonstrate how the simulation results can be managed using DW technologies. We also demonstrate how the use of integrity constraints can improve OLAP analysis. These constraints are used to maintain the quality of the warehoused data as well as to maintain the aggregations and queries, which will lead to better analysis, conclusions and decisions.

In this paper we present a semi-automatic method for designing and generating spatial data cubes in order to visualize and analyze the results of simulation models. In our approach users choose their fact of analysis, then the system derives automatically a set of possible measures, dimensions of analysis, and generates the corresponding spatial data cubes. The analysis and visualization of the spatial data cubes are carried out using appropriate SOLAP tools. We also present the SimOLAP system, developed to validate our approach.

Representations of topological relations between simple regions in description logics: from formalization to consistency checking
International Journal of Agricultural and Environmental Information Systems IJAEIS 4 (2), 2013
abs doi web bib

This paper proposes an operational approach to (1) formalize, in Description Logics (DL), the topological relations between simple regions and (2) automatically check whether a set of relations is consistent. The solution allows for the use of traditional DL reasoners (Pellet, Fact++, etc.) to check the consistency of relations and detect the sources of error. The solution does not require any specific extension of the DL or reasoner. The authors demonstrate how to apply this approach with Protégé and Fact++. Different spatial relations in agricultural and environmental applications are also provided to illustrate the possible uses of our method.

EIS Pesticides: An environmental information system to characterize agricultural activities and calculate agro-environmental indicators at embedded watershed scales
Agricultural Systems 122, 2013
abs doi web bib

The French 'Ecophyto 2018' program calls for a 50% reduction in pesticide use. Local authorities are required to design cost-effective measures to minimize the impact of farmers’ pesticides on water resources. A successful implementation of these new measures can only be achieved through a better understanding of the interactions between water, land use and the environment. One way of doing this is to calculate pesticide pressure and agro-environmental indicators (AEIs). However, this approach requires an effective information system that can process both the characteristics of the river basin and the agricultural activities using at least two embedded scales: the scale of the small agricultural catchment for action by farmers and the scale of a larger watershed for public decision making. To this end, an environmental information system (EIS Pesticide) for pesticide issues was created using spatial data warehouse technology. This system allowed qualifying agricultural activities along with river basin characteristics. Specific spatial objects were designed to characterize practices at the relevant scales. The axes of analysis allowed providing results at different levels of integration, for different dimensions e.g. time, sprayed surface area, or pesticide type. The system was tested using datasets collected in the Charente watershed and its sub-basins and calculated pesticide pressure indicators on demand for each aggregation level defined.

Spatial Data Warehouses (SDW) and Spatial OLAP (SOLAP) systems allow the storage and multidimensional analysis of huge volumes of geographic data. Existing SOLAP models do not take into account connectivity of spatial objects and consequently they do not natively integrate networks.

We implemented our UML profile using UML meta-model elements and OCL (Object Constraint Language) constraints with a Computer-Aided Software Engineering tool (MagicDraw). The implementation of the conceptual model in a database is presented using Oracle. / Les entrepôts de données spatiales (EDS) et les outils OLAP spatial (SOLAP) permettent le stockage et l'analyse multidimensionnelle d’une grande quantité de données géographiques.

The Water Framework Directive requires new tools for a better water quality monitoring
E-WAter, 2012
abs web bib

Our goal is to demonstrate the need to design a new type of environmentally friendly intrumentation to face the challenges of the Water Framework Directive. Rivers are spatially and timely structured ecological systems exhibiting hot spots and hot moments that contribute to their overall health status. However, current programs for monitoring water quality (grab samples and laboratory analysis) are based on sampling strategy that do not take into account the spatial and temporal heterogeneity of a water body. To reflect their actual dynamics, a paradigm shift is essential. This requires the development of new monitoring strategies and therefore new instrumentation. This new instrumentation must be able to measure at time scales appropriate to phenomena monitored and at a cost low enough to allow a sufficiently dense deployment in water bodies. We propose to enhance developing wireless networks of autonomous micro-sensors associated with mathematical processing of the collected data. The distinctive feature of this kind of smart sensor comes from the complete monitoring network expected, associating surface- and ground- waters chemistry, electronics and energy harvesting with smart data processing aiming to represent dynamic of basic ecological functions.

Entity-Relationship (ER) and Object-Oriented (OO) formalisms are often used to model environmental information of databases or computer programs. The majority of the environmental information are georeferenced. However, for 20 years, researchers have proposed different methods to adapt ER and OO to model spatial data. Spatial information is complex, and the goal is to simplify its representation in conceptual models. The goal of this paper is to propose a classification and a list of work in the area of ER and OO formalisms for spatial information. Numerous bibliographical references on the subject are also provided. The article targets mainly researchers working in the area of environment domain hoping to find a bibliographical entry to the subject.

Using OCL to model constraints in data warehouses
International Journal of Technology Diffusion 2 (3), 2011
abs doi web bib

Recent research works propose to use the Object-Oriented (OO) approach such as UML to model data warehouses. First, the present paper overviews these recent OO techniques. They aim to describe the facts and the different analysis dimensions of the data. Second, we will propose a tutorial of the Object Constraint Language (OCL) and we will show how this language can be used to specify constraints in OO-based models of data warehouse. Up to now, OCL has been only applied to describe constraints in software applications and transactional databases. So, we demonstrate in this paper how to use OCL to represent the different types of data warehouse constraints. Our paper is addressed to researchers working in the fields of business intelligence and decision support systems, who wish to learn about the major possibilities that OCL offer in the context of data warehouse, and to find citations that will allow them to learn about this formalism in greater detail.

Les nouvelles technologies de l’informatique embarquées sur les machines ou installées en parcelles (voire dans les airs avec les drones) connectent directement les champs avec les agriculteurs. Un objectif central est l’acquisition régulière et automatisée de données pour le suivi et l’aide à la décision en agriculture. Liée à des systèmes d’aide à la décision, une acquisition massive d’informations permet de suivre au mieux les cultures et faire des choix en matière de raisonnement des intrants (pesticides, irrigation, etc.), en accord avec le précepte de «la bonne dose au bon moment et au bon endroit». La collecte historisée des données permet aussi une analyse énergétique détaillée par type d’activités. Les données de certains capteurs tels que celles des stations météo peuvent être diffusées sur le Web afin de partager l’information auprès de différents acteurs. Au-delà des données de capteurs, les sites Web collaboratifs facilitent l’échange de bonnes pratiques en agriculture. De nombreuses données sont également saisies pour alimenter des outils de contrôle des activités agricoles.

Use of Sensor Data Warehouse for Soil Moisture Analysis
Automated enterprise systems for maximizing business performance (p. 43-57), IGI Global, 2015
abs doi web bib

More and more data are collected via sensors. Wireless networks can be implemented to facilitate the collection of sensors data and to reduce the cost of their acquisition. In this chapter, we present a general architecture combining Wireless Sensor Network (WSN) and Spatial Data Warehouse (SDW) technologies. This innovative solution is used to collect automatically sensor’s information and to facilitate the analysis of these data. The WSN used in this application has been deployed by Irstea and tested during several years in vineyards in South of France. The novel contribution presented in this chapter is related to the use of a SDW to manage data produced by geo-referenced sensor nodes. SDW is one of the most appropriate modern technologies for analyzing large data sets at different temporal and spatial scales. This type of databases is a specific category of information system used to integrate, accumulate and analyze information from various sources. These data are usually organized according to a multidimensional schema to facilitate the calculation of indicators. In this chapter, we introduce the development of a SDW storing the data collected by this WSN. The implemented data warehouse can allow users to aggregate and explore interactively data pro-duced by sensors. With this system, it is possible to visualize on a map the results of these aggregations.

Suite à l’atelier « Systèmes d’Information pour l’Environnement » de la conférence INFORSID 2014, les contributions les plus emblématiques des innovations en matière de SIE ont été sélectionnées et complétées par leurs auteurs. Dans le domaine de l’environnement, les informations caractérisant l’état du système ou son évolution sont souvent de nature diverse et nécessitent des moyens humains et/ou techniques importants pour les collecter, les analyser, les restituer. La diversité de ces informations et le suivi temporel du système étudié sur de longues périodes demandent une approche méthodologique rigoureuse relevant de celles des sciences expérimentales. Les articles du présent ouvrage abordent les verrous essentiels, du point de vue Système d’Information, qui ont été débattus dans l’atelier. Ceux-ci portent sur l’intégration de données diverses hétérogènes, l’expression de la connaissance, l’accessibilité des données et traitements via des architectures distribuées prenant en compte l’interopérabilité syntaxique et sémantique, l’interaction et la collaboration de divers types d’usagers, l’analyse historisée et/ou multicritères à des fins de gestion ou de décision. Ils traitent, au-delà de ces verrous, d’une riche palette de thématiques : l’aide à la gestion des ressources halieutiques, l’aide à la construction de connaissances en agronomie, l’aide à la gestion de données paléoenvironnementales, la mutualisation et l’accès aux ressources satellitales, l’aide à l’évaluation du risque de désertification et à l’évaluation de la qualité des ressources en eau. Le premier article « SICP : Système d’Information Collaboratif pour l’environnement et la gestion durable des Pêches en Mauritanie » de E. Beibou, J. Guitton et J. Barde relate la construction d’un système d’information virtuel dédié à la gestion halieutique. Celui-ci est conçu autour de la notion d’intégration de ressources hétérogènes, de calculs à la volée d’indicateurs appropriés, de leurs restitutions via une interface graphique tout en abordant l’apport de la collaboration entre divers acteurs scientifiques et gestionnaires. Le deuxième article « Construction d’une ontologie par transformation de systèmes d’organisation des connaissances et évaluation de la confiance » de F. Amarger, J.-P. Chanet, O. Haemmerlé, N. Hernandez et C. Roussey présente une méthode originale de création d’une base de connaissances (ontologie) à partir de transformations de plusieurs sources de connaissances. Ces sources sont issues des systèmes d’organisation des connaissances en l’occurrence Agrovoc, TaxRef et NCBI. La méthode s’appuie sur un module défini à l’aide de patrons de conception ontologiques et les sources étant pondérées par un score de confiance. Le troisième article « PALEOPYR : un système d’information pour la gestion et l’exploitation de données paléoenvironnementales sur le massif nord-pyrénéen » de É. Lerigoleur, F. Mazier, L. Jégou, M. Perret et D. Galop présente la conception du système d’information PALEOPYR. Ce dernier a pour objectif la reconstruction des dynamiques spatio-temporelles de la végétation pyrénéenne à partir de la capitalisation des données paléoenvironnementales produites au cours de 30 ans de recherche dans cette région. Le quatrième article « Mutualiser des données spatiales et des traitements en environnement » de J.-C Desconnets et M. Kazmierski s'attache à montrer en quoi les infrastructures de données spatiales (IDS) constituent des solutions de référence pour permettre aux utilisateurs de traiter des problèmes environnementaux de manière pluridisciplinaire à partir de données et de traitement divers et répartis. Au travers d’une vision abstraite, les auteurs décrivent les principaux éléments d’une IDS. L’approche préconisée est illustrée via la mise en ½uvre de l'IDS du projet Equipex GEOSUD. Le cinquième article « SIEL : système intégré pour la modélisation et l’évaluation du risque de désertification » de M. Loireau, M. Sghaier, B. Guerrero, F. Chouikhi, M. Fétoui, D. G. Leibovici, S. Debard, J.-C. Desconnets et N. Ben Khatra présente une réflexion menée sur la caractérisation et la spatialisation des pratiques et des ressources naturelles en interaction sur un espace donné dans une région sahélienne, dans le cadre de recherches relatives à la lutte contre la désertification. Il décrit une chaîne de traitements thématiques pour modéliser des unités de paysages ruraux et les causes et intensité du risque de désertification afférents, ainsi que la plateforme logicielle géomatique qui la met en ½uvre.

Storage of simulation result data: A database perspective
Automated enterprise systems for maximizing business performance ; (p. 58-70), IGI Global, 2015
abs web bib

DBMS is a traditional technology for the storage of business application data. In this chapter, we show that this technology can be of interest in scientific fields. We present a survey of the emergence of the concept of simulation result database. Scientific simulation models become more complex, use more data and produce more outputs. Stochastic models can also be simulated. In this case, numerous simulations are run in order to discover a general trend in results. The replications of simulation increase again the amount of produced data, which makes exploration and analysis difficult. It is also often useful to compare the results obtained in using different model versions, scenarios or assumptions (for example different weather forecasts). In this chapter, we provide several examples of projects of simulation result databases. We show that the database technology can help to manage the large volumes of simulation outputs. We also illustrate this type of projects on environmental databases storing pesticide transfer simulation results. We conclude in highlighting some trends and future works.

Special issue on agro-environmental decision support systems
Ecological Informatics vol.30 (p. 327-396), Elsevier, 2015
abs web bib

More and more agricultural and environmental data are now available. These data are produced by numerous methods: Terrestrial sensors, remote sensing systems, simulation models, Internet of things, etc. Agricultural and environmental Information Systems (IS) and Decision Support Systems (DSS) are two complementary approaches to use these data – their joint use allows managing information and making decisions based on their analysis in numerous applications for agriculture and environment. In the second edition of this special issue, we publish the latest advances in the field of informatics applied to agriculture and environment, focusing on the information and decision system technologies. The published papers range from the formal systems modelling to their development and experiments for decision-making. Several of these contributions show the combination of theoretical and practical methods issued from multidisciplinary research works. Different applications are presented in the fields of land use and pasture modelling, analyse of climate change impacts on agriculture, GM maize crop management, biotechnology and agriculture, fishery management. The communication and the interaction with users are two key points for the IS and DSS usability. The paper “An authoring tool for decision support systems in context questions of ecological knowledge” presents a new system to query more easily information and decision systems for biotechnology and agriculture. This method is based on a natural language interface in which the interactions between the user and the DSS reference the previous questions and answers. The system provides the capability to elide certain parts of the questions. The proposal is based on ontologies created semi-automatically by information integration. The architecture has been tested with information coming from the CEREALAB database and the Web (e.g., PubMed). The paper “Inference reasoning on fishers' knowledge using Bayesian causal maps” deals with a theoretical formalism for knowledge representation. The authors show how to use a new formalism called Bayesian causal map to model shellfish dredger activities and derive a decision systems allowing scenarios testing for fisheries management. Bayesian causal maps combine the advantages of cognitive maps and Bayesian networks. The resulting method is easy to use for expressing knowledge and for eliciting uncertain information. In the paper “Bayesian calibration of the Pasture Simulation model (PaSim) to simulate European grasslands under water stress”, the authors present a framework to interpret the model performance obtained with Bayesian calibration, in taking into account the case of a complex model for grassland. This model called PaSim is defined under certain climate conditions (precipitation reduction). The authors show an application for grasslands in Europe. In many places, urban zones tend to replace rural areas and it is important to be able to estimate the evolution of this tendency. In the paper “Supporting planning activities with the assessment and the prediction of urban sprawl using spatio-temporal analysis”, the authors analyse the spatio-temporal evolution of land and soil data. The authors introduce a model to measure variations occurred in land use, determine soil consumption and assess future trends. This model is applied to an Italian region. The managing of the coexistence between GM and non-GM maize crops is an important issue for numerous stakeholders. In the paper “Design of a decision support tool for managing coexistence between genetically modified and conventional maize at farm and regional levels”, the authors develop a model that can be used to inform the decision-maker on adventitious presence of GM grains in non-GM agricultural areas. Information are also provided about the uncertainty of the assessment and about the variability of adventitious presence. The implemented Web-based decision-support tool can compute the expected adventitious presence and its probability distribution in non-GM maize fields, according to distance and date. In “An open platform to assess vulnerabilities to climate change: An application to agricultural systems”, the authors introduce a new software platform for quantitative assessments support of vulnerability to climate change in agriculture. This software tool allows processing model-based inference related to agro-ecological system vulnerability to a variety of climate scenarios. A case study is introduced in the Massif Central region in France. The platform is used to characterize climate, soils and human management and to assess the vulnerability to climate change of grassland productivity at a fine geographical scale. In conclusion, this special issue describes some applications of information/decision systems and shows how these types of systems can help to manage the future challenges in the environmental and agricultural field. The world will have to face many challenges such as agricultural adaptation to climate change, land use evolution, coexistence of various agricultural systems, environmental constraints, etc. and information/decision systems will offer technical means to address these challenges.

This software tool allows processing model-based inference related to agro-ecological system vulnerability to a variety of climate scenarios. A case study is introduced in the Massif Central region in France. The platform is used to characterize climate, soils and human management and to assess the vulnerability to climate change of grassland productivity at a fine geographical scale. In conclusion, this special issue describes some applications of information/decision systems and shows how these types of systems can help to manage the future challenges in the environmental and agricultural field. The world will have to face many challenges such as agricultural adaptation to climate change, land use evolution, coexistence of various agricultural systems, environmental constraints, etc. and information/decision systems will offer technical means to address these challenges.}, }

Special issue on Information and Decision Support Systems for Agriculture and Environment
Ecological Informatics , Elsevier, 2015

Tasks such as monitoring and managing the ecological status of rivers, sharing environmental information, and helping farmers in their decision making are challenges for which information and decision support systems (DSS) represent effective solutions. New theoretical and technical challenges emerge from the integration of several scientific domains such as agronomy, ecology, mathematics, information technology and computer science. The objective of this special issue is to show how the latest advances in research in information and decision support systems can be applied to environmental and/or agricultural systems. This special issue has been organized in conjunction with the international workshop on Agricultural and Environmental Information and Decision Support Systems (AEIDSS 2013) held by the International Conference on “Computational Science and its Applications” (ICCSA 2013), June 24–27, 2013 (Ho Chi Minh City-Vietnam). The authors of the papers presented at this workshop have been invited to submit an extended version of their manuscript to this special issue, but the special issue call for papers was also open to external contributions. Twenty papers have been submitted to this special issue, and ten have been accepted for publication after revisions; each submission has been evaluated by three reviewers. The papers in this special issue address various current topics in informatics, such as data interoperability, linked open data, management of very large datasets, analysis of spatial and temporal information, and advanced formal methods for developing DSS. Here, we describe the main contributions found in the articles. The paper “Semantic Annotation of the CEREALAB database by the AGROVOC Linked Dataset” addresses linked open data. As indicated by the authors, the number of open data government initiatives is increasing worldwide, and new research is needed to help resource providers to publish and link their datasets. The authors have developed an experimental methodology to publish, link and enrich open data by performing automatic semantic annotation of schema elements. This approach is applied to the CEREALAB database, a public relational database designed for storing genotypic and phenotypic data on plant breeding. The authors of the paper entitled “A Knowledge Discovery Process for Spatiotemporal Data: Application to River Water Quality Monitoring” combine different methods to extract knowledge from water-quality data collected along rivers. The results can then be used to determine spatial indicators to assist experts in their interpretation of land use impacts on water quality. The paper “User Centered Ontology for Sri Lankan Farmers” proposes an ontological approach to provide context-specific information and knowledge to farmers based on their own context. As stated by the authors, a knowledge repository of agricultural information is proposed to respond to user queries, considering the context in which information is needed by farmers at different stages of the farming life cycle. The approach has been tested among farmers in Sri Lanka. The article “Evaluation of Urban Sprawl from space using open source technologies” presents a case study of analyzing urban sprawl using satellite data. The authors mention that these data are related to a coastal zone with the presence of sand and rocks, characterized by a fragmented ecosystem and small towns with an increasing rate of urbanization and soil consumption. Support vector machine algorithms are applied for satellite image classification, and open-source software is used. The paper “An Infrastructure-oriented Approach for supporting Biodiversity Research” presents D4Science, a data infrastructure that facilitates accessing and reusing biodiversity data. According to the authors, D4Science is an integrated and flexible environment based on existing databases and information systems. The authors highlight that the infrastructure facilitates the discovery, selection, access and processing of data. The paper “Model-Driven Engineering Applied to Crop Modelling” presents a framework to formalize mechanistic models of plant growth. This approach is based on a new domain-specific language dedicated to crop modeling and is used to facilitate the development of software applications for decision support systems. This framework allows modelers to generate software code automatically. The contribution entitled “Decision Support for Agri-Food Chains: A Reverse Engineering Argumentation-Based Approach” defines an objectives-driven decision support system defined for the end products of an agri-food chain. A reverse engineering technique and a logic-based formalization is proposed in the paper. The article “Increasing dependence on foreign water resources? An assessment of trends in global virtual water flows using a self-organizing time map” highlights that self-organizing time maps can be used to model, visualize and analyze virtual water fluxes. The virtual water is analyzed through the food trade in different countries. The final two papers show how data warehouse technology can be adapted, used and applied for environmental and ecological applications. The first of these papers proposes a method for the enrichment of phenotypic and genotypic data warehouse analysis, using question-answering systems. The main goal is to facilitate the decision making process in cereal breeding programs. The authors of the last paper propose to use hierarchical agglomerative clustering with the Gower similarity index to generate analysis dimensions in a data warehouse. The data set used is related to birds along the Loire River in France. As shown in these short des]criptions of the papers, this special issue presents new research advances in techniques related to information and DSS technologies, such as ontology-based systems, data warehouses, data mining and model-driven engineering. The application examples provided by the authors clearly show the role of these new technologies in the fields of agriculture, environment and ecology and their potential for the next few years

Parameterisation of individual working dynamics
Empirical Agent-Based Modelling – Challenges and Solutions. Volume 1, The Characterisation and Parameterisation of Empirical Agent-Based Models (p. 133-169), Springer, New York, USA, 2014
abs doi web bib

During the PRIMA European project, we conceived a conceptual model dedicated to the study of the evolution of the European Rural Areas in terms of demography and occupation of their populations. This is a hybrid agent-microsimulation model considering inhabitants as the basic elements composing in households. On the other hand, municipalities are the basic spatial element and the providers for employment and housings. This chapter presents the main objects and their relationships are identified as a first generic way to parameterize the dynamics of such a conceptual model for an implementation of a European region. This chapter explains how dynamics can be parameterised from data for an implementation for a French region. It focusses on the dynamics of work statuses and professions which can be derived from the European Labour Force Survey (LFS). The individual is considered from her entering on the labour market until the moment she decides to retire. Meanwhile, she can be fired, searching for a job when she is unemployed or already employed but also deciding becoming inactive for a while. Jobs are defined by a profession and an activity sector. The job offer is located at the municipality level and can correspond to the searched profession of an individual having a municipality of residence. The French implementation is described starting from the employment survey in France, which is the French declination of the LFS.

CMF: A Crop Model Factory to improve scientific models development process
Progressions and Innovations in Model-Driven Software Engineering (p. 181-195), IGI Global, Pennsylvania, USA, 2013
abs web bib

This chapter shows how Model Driven Engineering (MDE) can contribute to the production of Crop models. The ITK firm works in agronomy, it designs digital models and Decision Support Systems for croppers. Common model development at ITK relies on a dual implementation. The first one being in Matlab® is usually proposed by agronomists but for industrial purposes software engineers translate this model in Java. This leads to double implementation, maintenance and heavy production costs. To deal with this efficiency problem, we have used a MDE approach to produce a Crop Model Factory (CMF). For this factory we propose a DSML (Domain Specific Modeling Language) formalized by a metamodel. In this chapter we present this DSML, the concrete syntax retained for the factory and its implementation in a tool enabling automatic code generation. The resulting Crop Model Factory (CMF) prototype is the fruit of an interdisciplinary collaboration and we also present feedback on this working experience.

Special issue on environmental and agricultural data processing for water and territory management
International Journal of Agricultural and Environmental Information Systems IJAEIS 2 (2), IGI Global, Hershey, USA, 2011
abs web bib

Nowadays, new information and communication technologies make it possible to collect considerable amounts of geo-referenced data. These data are generated by remote sensing systems or other computer applications. In order to take benefits of these valuable data, some new solutions propose to integrate them into Information Systems and Decision Support Systems. These systems represent increasingly effective and performing tools to tackle issues concerning the processing of environmental data related to water and territory. Indeed, they allow taking into account characteristics of these complex data and phenomena (such as semantics, spatial components, etc.) and of environmental problems (social theories, simulation models, participative issues, etc.).

These data are generated by remote sensing systems or other computer applications. In order to take benefits of these valuable data, some new solutions propose to integrate them into Information Systems and Decision Support Systems. These systems represent increasingly effective and performing tools to tackle issues concerning the processing of environmental data related to water and territory. Indeed, they allow taking into account characteristics of these complex data and phenomena (such as semantics, spatial components, etc.) and of environmental problems (social theories, simulation models, participative issues, etc.).

SKOS est un schéma RDF utilisé pour stocker et publier sur le web de données liées des thésaurus ou des taxonomies. Lors du développement d’un thésaurus, il est utile de détecter automatiquement les concepts qui violent les contraintes d’intégrité. Cet article présente le cas d’usage d’un développement manuel d’un thésaurus monolingue. Ce thésaurus porte sur l’usage des cultures en France. Dans cet article, nous avons spécifié diverses contraintes d’intégrité. Pour vérifier ces contraintes un ensemble de requêtes SPARQL a été défini. Ces requêtes permettent à la fois de vérifier des contraintes d’intégrité propres à tous les thésaurus stockés au format SKOS, mais aussi des contraintes propres à notre thésaurus.

Le but est de proposer un processus d’annotation automatique qui permet de générer des annotations complexes accessibles via un sparql endpoint. Nous partons d’annotations manuelles des portions de textes, ces annotations permettent d’identifier les entités sémantiques à repérer dans le texte. Nous nous appuyons, dans la mesure du possible, sur des schémas de données et des ontologies disponibles.

More and more data sets are published on the linked open data. Reusing these data is a challenging task as for a given domain, several data sets built for specific usage may exist. In this article we present an approach for existing knowledge bases fusion by taking into account incompatibilities that may appear in their representations. Equivalence mappings established by an alignment tool are considered in order to generate a subset of compatible candidates. The approach has been evaluated by domain experts on datasets dealing with agriculture.

We propose a method for building a knowledge base addressing specific issues such as covering end-users’ needs. After designing an ontology module representing the knowledge needed, we enrich and populate it automatically with knowledge extracted from existing sources such as thesauri or classifications. The originality of our proposition is to propose ontological object candidates from existing sources according to their relatedness to the ontological module and to their trust score. This paper describes the trust measures we propose which are obtained by analysing the consensus found in existing sources. We consider that knowledge is more reliable if it has been extracted from several sources. Our measures has been evaluated on a real case study with experts from the agriculture domain.

Il permet aux décideurs d’explorer et de visualiser les entrepôts de données spatiales en utilisant des tables multidimensionnelles « pivot table » et d’affichage cartographique des faits sur des cartes interactives. Dans cet article, nous présentons un prototype pour la visualisation cartographique des requêtes SOLAP. Ce prototype se base sur une architecture orientée services (SOA).

The design of Spatial OLAP (SOLAP) applications consists of (i) Spatial Data Warehouse (SDW) model design and (ii) SOLAP visualization definition because a specific set of understandable and readable cartographic visualizations corresponds to a particular type of SOLAP query. Unfortunately few works investigate geovisualization issues in SOLAP systems and propose new methodologies to visualize spatio-temporal data, and no works investigate tools for readable SOLAP cartographic displays. Moreover, some works propose adhoc methodologies for DWs and SDWs exclusively based on data and user analysis requirements. Therefore, we present in this paper (i) a new geovisualization methodology for SOLAP queries that yields readable maps and (ii) a new prototyping design methodology for SOLAP applications that accounts for geovisualization requirements.

A data cube design and construction methodology based on OLAP queries

Business Intelligence systems provide an effective solution for multidimensional online computing and analysis from large volumes of data. In the decision making process, analyzed data are typically stored in a set of cubes often heterogeneous. Most of the time, the structure of these cubes is unknown by decision makers. Our goal is to enable decision makers to express their need via a query in natural language. In this paper, we deal with the problem of data cube design and construction according to a user query where the expressed need is dispersed on more than one cube. We propose a cubes design and construction approach based on fusion of cubes containing a part of the user's need. We validate our approach via a tool, called "Design-Cubes-Query", that implements our approach and we show its use through a case study.

Enrichissement de schéma multidimensionnel en constellation grâce à la classification ascendante hiérarchique

Les hiérarchies sont des structures cruciales dans un entrepôt de données puisqu’elles permettent l’agrégation de mesures dans le but de proposer une vue analytique plus ou moins globale sur les données entreposées, selon le niveau hiérarchique auquel on se place. Cependant, peu de travaux s’intéressent à la construction de hiérarchies, via un algorithme de fouille de données, prenant en compte le contexte multidimensionnel de la dimension concernée.

Experiments on the use of knowledge management tools for agriculture
12th European IFSA Symposium, 12/07/2016-15/07/2016, Newport, GBR (p. 8), 2016
abs web bib

Agriculture must be both sustainable and economically viable. Sustainable agriculture requires new knowledge and expertise. However, knowledge management is not sufficient in current sustainable agriculture. To overcome this, we have made the assumption that the knowledge management practices used in industry can be transferred in agriculture. In this paper, we propose to apply to agriculture, the methodological tools developed by the French knowledge management group. These tools are based on theoretical approaches for the transformation of explicit and tacit knowledge within an organization. These tools are generic and suitable for any knowledge. We have tested the tool CFK for knowledge criticality in order to identify the knowledge to make explicit within a farm. This knowledge is critical because they are valuable, rare, complex and difficult to formalize. They must therefore be managed. We have determined the criticality of knowledge in a farm for organic agriculture field crops, in prairies and on various flora grain legumes. In the French research project TATABOX related to the agro-ecological transition study in a land between Tarn and Aveyron in France, we also have experimented another methodological tool (TRACO) for characterizing the most appropriate knowledge transfer tools to use between an agricultural cooperative and farmers. Among 16 knowledge transfer methods proposed, TRACO allow highlighting supervised self-education but also traditional teaching courses, communities of practices and workshops. Our conclusion is that the proposed knowledge management tools seem relevant to manage knowledge in agriculture, but they still require training and adaptation to agricultural fields.

Henceforth, new generations of Wireless Sensor Networks (WSN), as part of the Internet Of Things (IoT), have to be able to adapt their behaviour to collect, from the study phenomenon (or feature of interest), quality data for long period of time. In this article, we propose a new formalisation for the design and the implementation of context-aware systems. To illustrate this whole proposition, an environmental use case, the study of flood events in a watershed, relying on a WSN for the data collection, is presented.

Spatial OLAP systems aim to interactively analyze huge volumes of geo-referenced data. They allow decision-makers to on-line explore and visualize warehoused spatial using pivot tables, graphical displays and interactive maps. On the other hand, it has been recently shown that chorem maps represent an excellent geovisualization technique to summarize spatial phenomena. Therefore, in this paper we introduce a framework being capable to merge the interactive analysis capability of SOLAP systems and the potentiality of a chorem-based visual notation in terms of visual summary. We also propose a general architecture based on standards to automatically extract and visualize chorems from SDWs according to our framework

Data Warehouse (DW) and OLAP systems are effective solutions for the online analysis of large volumes of data structured as cubes. Usually organizations and enterprises require several cubes for their activities. In this context, we define a new kind of queries: “Top-k Cubes queries”. Top-K cubes queries allow searching the most relevant k-cubes among a collection of cubes. Then, in this paper we propose a first framework for Top-K cubes queries where queries are expressed in natural language to meet the easiness need of unskilled IT decision-makers.

Mixed driven refinement design of multidimensional models based on agglomerative hierarchical clustering

Data warehouses (DW) and OLAP systems are business intelligence technologies allowing the on-line analysis of huge volume of data according to users’ needs. The success of DW projects essentially depends on the design phase where functional requirements meet data sources (mixed design methodology). However, when dealing with complex applications existing design methodologies seem inefficient since decision-makers define functional requirements that cannot be deduced from data sources (data driven approach) and/or they have not sufficient application domain knowledge (user driven approach). Therefore, in this paper we propose a new mixed refinement design methodology where the classical data-driven approach is enhanced with data mining to create new dimensions hierarchies. A tool implementing our approach is also presented to validate our theoretical proposal.

Une nouvelle approche mixte d’enrichissement de dimensions dans un schéma multidimensionnel en constellation : application à la biodiversité des oiseaux
11èmes journées francophones sur les Entrepôts de Données et l'Analyse en ligne, 02/04/2015-03/04/2015, Bruxelles, BEL (p. 65-80), RNTI, 2015
abs web bib

Les entrepôts de données (DW) et les systèmes OLAP sont des technologies d’analyse en ligne pour de grands volumes de données, basés sur les besoins des utilisateurs. Leur succès dépend essentiellement de la phase de conception où les exigences fonctionnelles sont confrontées aux sources de données (méthodologie de conception mixte). Cependant, les méthodes de conception existantes semblent parfois inefficaces, lorsque les décideurs définissent des exigences fonctionnelles qui ne peuvent être déduites à partir des sources de données (approche centrée sur les données), ou lorsque le décideur n’a pas intégré tous ces besoins durant la phase de conception (approche centrée sur l’utilisateur). Cet article propose une nouvelle méthodologie mixte d’enrichissement de schémas en constellation, où l’approche classique de conception est améliorée grâce à la fouille de données dans le but de créer de nouvelles hiérarchies au sein d’une dimension.

Leur succès dépend essentiellement de la phase de conception où les exigences fonctionnelles sont confrontées aux sources de données (méthodologie de conception mixte). Cependant, les méthodes de conception existantes semblent parfois inefficaces, lorsque les décideurs définissent des exigences fonctionnelles qui ne peuvent être déduites à partir des sources de données (approche centrée sur les données), ou lorsque le décideur n’a pas intégré tous ces besoins durant la phase de conception (approche centrée sur l’utilisateur). Cet article propose une nouvelle méthodologie mixte d’enrichissement de schémas en constellation, où l’approche classique de conception est améliorée grâce à la fouille de données dans le but de créer de nouvelles hiérarchies au sein d’une dimension.

SKOS Sources Transformations for Ontology Engineering: Agronomical taxonomy use case

Sources like thesauri or taxonomies are already used as input in ontology development process. Some of them are also published on the LOD using the SKOS format. Reusing this type of sources to build an ontology is not an easy task. The ontology developer has to face different syntax and different modelling goals. We propose in this paper a new methodology to transform several non-ontological sources into a single ontology. We take into account: the redundancy of the knowledge extracted from sources in order to discover the consensual knowledge and Ontology Design Patterns (ODPs) to guide the transformation process. We have evaluated our methodology by creating an ontology on wheat taxonomy from three sources: Agrovoc thesaurus, TaxRef taxonomy, NCBI taxonomy.

From Volunteered Geographic Information to Volunteered Geographic OLAP: A VGI data quality-based approach

Volunteered Geographic Information (VGI) represents a valuable source of information. At the same time this data presents new data quality issues such as credibility. In this paper, we investigate the integration of VGI in Spatial OLAP (SOLAP) systems, which allow analyzing huge volume of geographic datasets. By means of a real case study, we highlight the similarities and differences of these two kinds of systems. We propose a methodology to handle VGI data quality issues during the warehousing and OLAPing phases. In particular, we define a new aggregation ETL operator based on the VGI credibility. We also present a spatio-multidimensional model that provides decision-makers with a general description of the correctness of the SOLAP aggregations.

Usually, DW design is a complex, and time and resources consuming task. Then, DWexperts are necessary during design and implementation phases.

Agricultural energy consumption is an important economic, environmental and social issue. The French national project EDEN aims at the analysis of energies consummations for two main activities: Agricultural productions and dairy activities using OLAP systems. In this paper, we focus on energetic assessment of dairy activities. We present a multidimensional model allowing for monitoring of energies used for dairy activities. The developed model is complex but in counterpart it allows for analysis of inputs, outputs and their relations of the dairy farm system. In this way decision-makers can understand and correlate energetic trends overall the global production process.

In the history of the WSN, unexpected routing behaviors is always a main issue of the large scale WSN deployments. Considering the high cost of building a real deployment, network simulators are often used in this domain. However, the original problem is still not solved although the era of IoT has been coming. A new concept of LLN is emerging. We realize that, no matter how wonderful the results from the simulation scenarios and thorough testing, the problems, such as bad performance or even severe system failures due to suboptimal routing path, would still happen in the real-world system. Our context-aware tool-set can help to build the simulation topology which is more close to the real network through mapping a serial routing metrics defined by IEFT ROLL working group and the link situation of the actual network. We believe our suggestion of bridging virtual and physical worlds reflected on our proposed tool-set could conduct more precise routing-targeted simulations. Moreover, by close-loop method, the knowledge and analyzed simulation results can lead us to improve the routing topology of the deployed LLN.

Spatial Data Warehouses (SDW) and Spatial OLAP (SOLAP) systems are well-known Business Intelligence technologies that aim to support multidimensional and online analysis of huge volumes of datasets with spatial reference. Spatial vagueness is one of the most neglected imperfections of spatial data. Although several works propose new ad-hoc models for handling spatial vagueness in information systems, the implementation of those models in Spatial DBMS and SDW is still in an embryonic state. Thus, in this paper, we present a new design method for SOLAP datacubes that allows handling vague spatial data analysis issues. This method relies on a risk management method applied to the potential risks of data misinterpretation and decision-makers’ tolerance levels to those risks. We also present a system implementing our method

Les approches disponibles pour concevoir un entrepôt de données, y compris celles adoptant les pratiques agiles, sont basées sur l’hypothèse que les données sources sont connues et disponibles à l’avance. Cette hypothèse n’est pas toujours vraie dans certains contextes. Pour pallier ces limites, nous proposons ProtOLAP, une méthodologie assistée par un outil de prototypage rapide.

Data Warehouses (DWs) are large repositories of data aimed at supporting the decision-making process by enabling flexible and interactive analyses via OLAP systems. Rapid prototyping of DWs is necessary when OLAP applications are complex. Some work about the integration of Data Mining and OLAP systems has been done to enhance OLAP operators with mined indicators, and/or to define the DW schema. However, to best of our knowledge, prototyping methods for DWs do not support this kind of integration. Then, in this paper we present a new prototyping methodology for DWs, extending [3], where DM methods are used to define the DW schema. We validate our approach on a real data set concerning bird biodiversity

Wireless sensor networks (WSN) are one of the important technologies of the 21st century. Most researchers and technical analysts believe that, in the near future, these micro-sensors will be integrated throughout anywhere of our life. In recent years, IoT and WoT gradually became a very popular and hot topic especially in the area of WSN. However, with the development of IoT, the devices that can provide information can be heterogeneous which generate different issues. In this thesis, we considered the Semantic Web associated to Ontology as a possible solution to solve some of these problems. Technologies of the Semantic Web, such as RDF language, are, for example, used to support the publication of structured data on the Web and their interoperability in the Linked (Open) Data. Besides, the 6LoWPAN (IPv6 over Low power Wireless Personal Area Networks) protocol has allowed the use of IPv6 protocol stack in the field of WSN. The use of this protocol should enable, in theory, to have all the nodes of a WSN individually "visible" from the Internet. So, relying on research works currently performed in the context of the WoT as well as the 6LoWPAN protocol, it should be possible to integrate WSN dedicated to environment and agriculture in the IoT.

An integrated survey in plant disease detection for precision agriculture using image processing and wireless multimedia sensor network
2014
abs web bib

Plant diseases detection is essential and critical operation and can affect crop yield. Pesticides play an important role in pest control but their role is under criticism due to perceived excessive use and potentially harmful to the environment and persons. This paper intends to focus on the survey of plant disease detection using image processing and Wireless Sensor Network/Wireless Multimedia Sensor Network (WSN/WMSN) techniques in precision agriculture (PA) field. The machine vision based approach uses size, shape, texture, color and location based features to detect disease affected leaf or plant. As the development of Internet of Things (IoT) technology, the scalar sensing data and multimedia video/audio data would improve the detections and provide efficient long-term prediction in the PA application. This survey will also present a study about the current existing issues and promote an emulation based architecture that is able to combine these different emerging technologies practically.

To participate to the Linked Data for agriculture, we wanted to use AGROVOC that is a multilingual thesaurus maintained by FAO with more than 40,000 terms. We present here a state of the art about techniques to transform a domain ontology from thesaurus. For this we will study ten methodologies along three major axes: the extraction of classes, the extraction of the hierarchy and the relation extraction. We were able to identify some complex aspects from methodologies such as the complexity of disambiguation or validation that led a return to manual techniques. / Afin de participer au web de données pour l'agriculture, nous avons voulu utiliser AGROVOC qui est un thésaurus multilingue maintenu par la FAO comportant plus de 40.000 termes.

Spatial Data Warehouses (SDW) and Spatial Online Analytical Processing (OLAP) systems are Business Intelligence technologies allowing efficient and interactive analysis of huge volume of geo-referenced data. Some efforts have been done to integrate complex spatial data such as field, generalized spatial data, etc., in such systems, at conceptual and physical levels. However, existing works do not support spatial networks (i.e. road networks), which define topological connections between spatial data. Thus, mandatory analysis capabilities offered by spatial networks cannot be introduced in the decision-making process powered by SOLAP systems. In this paper, motivated by relevance of using standards for the conceptual design of Data Warehouses and Geographic Information Systems, we propose a UML profile for data warehouses integrating spatial networks. We define our conceptual model in the Computer-Aided Software Engineering tool MagicDraw, and we propose a relational implementation in Oracle Spatial

ProtOLAP: Rapid OLAP prototyping with on-demand data supply
International workshop on Data warehousing and OLAP, 28/10/2013-28/10/2013, San Francisco, USA (p. 61-66), 2013
abs web bib

The approaches to data warehouse design are based on the assumption that source data are known in advance and available. While this assumption is true in common project situations, in some peculiar contexts it is not. This is the case of the French national project for analysis of energetic agricultural farms, that is the case study of this paper. Here, the above-mentioned methods can hardly be applied because source data can only be identified and collected once user requirements indicate a need. Besides, the users involved in this project found it very hard to express their analysis needs in abstract terms, i.e., without visualizing sample results of queries, which in turn would require availability of source data. To solve this deadlock we propose ProtOLAP, a tool-assisted fast prototyping methodology that enables quick and reliable test and validation of data warehouse schemata in situations where data supply is collected on users’ demand and users’ ICT skills are minimal.

While this assumption is true in common project situations, in some peculiar contexts it is not. This is the case of the French national project for analysis of energetic agricultural farms, that is the case study of this paper. Here, the above-mentioned methods can hardly be applied because source data can only be identified and collected once user requirements indicate a need. Besides, the users involved in this project found it very hard to express their analysis needs in abstract terms, i.e., without visualizing sample results of queries, which in turn would require availability of source data. To solve this deadlock we propose ProtOLAP, a tool-assisted fast prototyping methodology that enables quick and reliable test and validation of data warehouse schemata in situations where data supply is collected on users’ demand and users’ ICT skills are minimal. To this end, users manually feed sample realistic data into a prototype created by designers, then they access and explore these sample data using pivot tables to validate the prototype.}, }

To help decision makers, Spatial Data Mining and Spatial OLAP systems have been developed for exploring and synthesizing huge volume of geo-referenced heterogeneous data. These systems rely on closed, well-integrated and structured (according to an analysis goals model, the so-called spatio-multidimensional model) huge data sets. On the other hand, new geographic technologies such as geospatial positioning, web mapping and wikis gave birth to Collaborative Web-based maps systems that allow experts and amateurs (volunteers) to create and share thematic oriented geographic information, leading to the concept of Volunteered geographic information (VGI). While VGI systems are gaining momentum, they suffer from drawbacks such as weak data credibility and quality ; and they do not provide techniques to efficient handle analysis of historical data. As a result, there is a urgent need for investigating the integration of VGI into SOLAP : the work described in this paper attempts to fulfill this need.

Design of complex spatio-multidimensional models with the ICSOLAP UML Profile: An implementation in MagicDraw

Spatial Data Warehouse and SOLAP systems allow analyzing huge volume of georeferenced data. SOLAP applications are usually complex needing advanced static and dynamic modelling properties. In particular, SOLAP applications require: multi-granular measures and complex aggregations based on aggregate functions depending on dimensions, hierarchies and levels. In this demo paper, motivated by the lack of conceptual spatio-multidimensional models based on standard languages and supporting such complex modelling requirements, we present a new UML profile for complex spatial data cubes. We implement our profile in the commercial CASE tool called MagicDraw. Using a real environmental case study, we show the theoretical and technical effectiveness of our proposal.

SANBA Tool: Knowledge Capitalisation and Lessons Learned on Dams and their Safety

Much is known about dam design, construction and failure and degradation modes, though the information is scattered and sometimes lacks clarity. Consequently, it is interesting to develop tools that allow gathering, capitalizing and making explicit current and future information. These tools can be learning or documentation support systems. In this article, we present the prototype tool called SANBA, composed of a knowledge base, SANBA-dom, specifically developed for dam design, construction and failure and degradation modes (domain knowledge), coupled with a case base, SANBA-cas, which gives a detailed description of incidents and accidents that have occurred on structures (diagnoses, consequences and corrective actions). The method relies on 4 main stages: determining study granularity, field identification and structuring, implementing a computer tool and instantiation. Validations were carried out after the identification and instantiation stages. Two different technologies were used for the 2 components of the SANBA tool: the SANBA-cas component was implemented using Symfony (framework PHP open-source) and the SANBA-dom was implemented using a Wiki technology. Web technologies make formalized knowledge more accessible and simplify its capture. These bases are currently being filled and validated at Irstea Aix-en-Provence. Later, they will be accessible to external users for consulting and writing tasks as a function of the rights conferred to each type of user.

Wireless multimedia sensor network for plant disease detections

To minimize pesticide use it is necessary to detect at the early stage the present of plant disease and perform local treatment instead of global systematic treatment. To achieve this goal, one of the techniques may be used is image processing through the deployment of WMSN in the cultivated field. However, transmitting massive image data wirelessly will increase significantly network traffic and particularly energy consumption. In this paper, we propose a plant disease detection approach which is designed to run on the resource-constrained WMSN nodes. Through the analysis of plant images acquired by the node, this new approach is able to make a preliminary local decision on the health condition of the plant and determine the necessity of sending back images to the control centre for further inspection, thus improving the efficiency of the monitoring network. The complete method includes image segmentation based on both color and shape, and uses 2D histogram as the feature for classification. Experiments on the plant images with nutrient deficiency symptoms show the classification accuracy of the new method reaches 87.5%.

Les données utiles au calcul d’indicateurs de performances énergétiques des exploitations agricoles à différentes échelles nécessitent une collecte plus fine et un stockage plus important d’informations auxquels seules les avancées technologiques peuvent répondre. Un travail de recensement des solutions technologiques existantes montre que de plus en plus de solutions sont aujourd’hui disponibles, notamment sur les nouveaux agroéquipements, pour fournir un grand nombre de données utiles au calcul de ces indicateurs. Un important travail reste cependant à réaliser pour proposer aux agriculteurs des solutions bas-coûts, faciles à mettre en ½uvre et totalement adaptées à leurs besoins pour faciliter la mesure, la collecte et le stockage des informations de façon automatique et raisonnée. En matière de systèmes d’informations, la technologie des entrepôts de données spatiales fait émerger de nouvelles solutions pour le recueil et l’utilisation décisionnelle des données. Ces technologies permettent d’établir, sur des données collectées et archivées, toutes sortes d’indicateurs résultant d’opérations agrégées en fonction de différents critères (périodes de temps, types de machines ou d’outils, types de travaux, etc.), ainsi que des découvertes de relations causales et de classification de données. Les récentes avancées technologiques (capteurs embarqués, localisation GPS, communication et réseaux sans fil) et le déploiement de systèmes d’acquisition et d’information dans les entreprises agricoles permettent d’envisager aujourd’hui d’accéder en continu à des données de qualité, en quantité suffisante et à une échelle plus fine de gestion. L’intégration de ces solutions technologiques dans l’exploitation agricole contribuera à améliorer les connaissances sur l’évaluation des dépenses énergétiques et le pilotage énergétique par une gestion raisonnée des informations collectées à une échelle plus fine de temps (jour, semaine, mois, année civile, année culturale, cycle de production, etc.), d’espace (parcelle/bâtiment, etc.) et de production (culture/lot d’animaux, chantier, tâche, outil, opérateur, etc.).

Spatial OLAP systems allow multidimensional analysis of huge volume of spatial data. Spatial vagueness is one of the most transparent and current imperfections of spatial data. Although several works propose new ad-hoc models for handling spatial vagueness in Spatial DBMS, the implementation of those models in conventional systems and Spatial Data Warehouses (SDW) is still in an embryonic state. Thus, to help reduce that uncertainty and its consequences in SOLAP analysis, we present a new approach for designing spatial data cubes based on users tolerance to the risk of misusing datacubes.

However, this field knows a very fast progress and new technologies are involved. One of the hottest trends of the future WSN is the I/WoT ‘Internet/Web of Things’. For the wireless medium access and radio transmission (MAC and PHY), I/WoT has chosen the IEEE 802.15.4 standard. Some researchers have proposed simulation models to analyze this standard in different simulation environment. In this paper we propose a new WPAN model for the NS-3 simulator. This model implements most of the IEEE 802.15.4 standard feature and modes of operations. Furthermore, a 6LoWPAN Model is used to incorporate the IEEE 802.15.4 into the IPv6 architecture by interfacing the IPv6 model of NS-3 with our new IEEE 802.15.4 standard model. Thus, we believe that this WPAN work can be seen as a foundation for future I/WoT simulation on NS-3.

Le problème du stockage et du requêtage de gros volumes de grilles spatialisées est un verrou à traiter. Dans cet article, nous proposons une méthode pour optimiser les requêtes visant à agréger des grilles matricielles stockées dans des bases de données. Dans notre approche, nous proposons d’estimer le résultat réel plutôt que calculer le résultat exact. Ceci permet de gagner en temps d’exécution. Un avantage de notre méthode est qu’elle ne nécessite pas de re-implémenter une partie du système de gestion de base de données. Notre approche se base sur une nouvelle structure de données et sur un modèle spécifique de requêtes SQL. Nous appliquons ici nos travaux aux entrepôts de données relationnels.

Probabilistic simulation for probabilistic data-aware business processes

There is a wide range of new applications that stress the need for business process models that are able to handle imprecise data. This paper studies the underlying modelling and analysis issues. It uses as formal model to describe process behaviours a labelled transitions system in which transitions are guarded by conditions deﬁned over a probabilistic database and presents an approach for testing probabilistic simulation preorder in this context. A complexity analysis reveals that the problem is in 2-exptime, and is exptime-hard, w.r.t. expression complexity while it matches probabilistic query evaluation w.r.t. data-complexity.

La performance des entrepôts de données est classiquement assurée grâce à des structures comme les index ou les vues matérialisées. Dans ce contexte, des modèles de coût permettent de sélectionner un ensemble pertinent de ce type de structures. Toutefois, cette sélection devient plus complexe dans les nuages informatiques, car en plus des temps de réponse, il faut simultanément optimiser le coût monétaire. Nous proposons dans cet article de nouveaux modèles de coût intégrant le paiement à la demande en vigueur dans les nuages. Sur la base de ces modèles, nous définissons un problème d’optimisation consistant à sélectionner, parmi des vues candidates, celles à matérialiser pour minimiser le coût d’interrogation et de maintenance, ainsi que le temps de réponse pour une charge de requêtes donnée. Dans un premier temps, nous optimisons les deux critères séparément : le temps est optimisé sous contrainte de coût et vice versa. Notre proposition est ensuite validée de manière expérimentale.

In ontology design, an Ontology Design Pattern (ODP) is a modeling solution to a recurrent ontology design problems. As opposed to ODP, antipatterns are bad modeling practices. This paper deals with detection of antipattern for debugging purpose of huge ontologies. We focus on the detection of the Onlyness Is Loneliness (OIL) antipattern. We propose an antipattern detection method based on ontology transformations and SPARQL queries. This approach does not need reasoner to detect antipattern. Our method detects candidates of OIL antipattern. These candidates localize class definitions where OIL occurrences can appear. This enables to draw ontology developer's attention to avoid errors during ontology development process. We conduct some experiments to detect OIL antipattern in an OWL ontology corpus obtained from the Watson ontology search engine.

This paper focuses on the routing protocol for driving safety that vehicle collects state message from roadside sensors in VANET-WSN. Routing Protocol for Low Power and Lossy Networks (RPL), a tree-based routing protocol, adapts naturally to our routing requirement. But RPL is designed for static wireless sensor network, so we need to modify RPL to fit in with high dynamic topology of VANET-WSN. For the first time, we utilize Geographical Information (GI) as the metric for RPL (GI-RPL), which lets RPL in a timely fashion. We also propose some strategies for tuning RPL in VANET-WSN. To demonstrate the performance of GI-RPL, we set up a simulation by using Cooja and compare with another modified RPL. The result of simulation shows that GI-RPL has high Package Delivery Ratio (PDR), reasonable overhead and low delay.

Innovation in agricultural machinery: Analysis of two examples for the reduction of pesticides
CIOSTA XXXV , 03/07/2013-05/07/2013, Billund, DNK (p. 8), 2013
abs web bib

One of the main challenges for today's agricultural engineering and science in Europe is to boost concrete and successful innovation to produce more and, at the same time, in a more sustainable way. ICT and new intelligent systems such as robotics have a great potential to meet these challenges, as recognized by European and national agenda and policies. However, the innovation process is a complex process which often fails to reach the market, regardless of the potential of the technology used. A lot of studies and initiatives were made, in agriculture and other areas, to have a better understanding of this innovation process and to improve its working. These range from studying the spread of innovation and include the use of new technologies or systems to improve it, the involvement of end users in the innovation process, the acceptance of technologies and many more. These studies highlighted that success or failure of an innovation isn’t often due to technical or scientific problems but „generally involves ethical; social, management, organizational and institutional problems.”ii However, taking into account this complexity still remains difficult to study and manage. In this paper, a specific Public-Private Partnerships Action of the ICT AGRI Era-net is presented in the crop protection area. This one-year action aimed to gather together the potential players involved in the innovation process at the European level for crop protection and to boost two concrete innovation using ICT and robotics to reduce the use of pesticides. A collective work on „smart adjustments tools for sprayers‟ and on “combined robotic solutions‟ were made in order to develop innovation which would offer to farmers more intelligent machinery for crop protection. During this work, links with other similar European actions and networks such as ENDURE were made. The main interest of the study is the method used, based on value chain, but improved to encompass the whole complexity of the innovation process by integrating technological/scientific elements as well as sociological, economic or organizational aspects. The main conclusions of this study confirmed that a complex approach combining technological and social aspects is essential to understand and manage the innovation process. Some specificities of ICT innovation in agriculture, especially in this for crop protection, were highlighted at several levels (economical, social and technological). This first experiment on this methodology also pointed out new directions of research on innovation.

A lot of studies and initiatives were made, in agriculture and other areas, to have a better understanding of this innovation process and to improve its working. These range from studying the spread of innovation and include the use of new technologies or systems to improve it, the involvement of end users in the innovation process, the acceptance of technologies and many more. These studies highlighted that success or failure of an innovation isn’t often due to technical or scientific problems but „generally involves ethical; social, management, organizational and institutional problems.”ii However, taking into account this complexity still remains difficult to study and manage. In this paper, a specific Public-Private Partnerships Action of the ICT AGRI Era-net is presented in the crop protection area. This one-year action aimed to gather together the potential players involved in the innovation process at the European level for crop protection and to boost two concrete innovation using ICT and robotics to reduce the use of pesticides. A collective work on „smart adjustments tools for sprayers‟ and on “combined robotic solutions‟ were made in order to develop innovation which would offer to farmers more intelligent machinery for crop protection. During this work, links with other similar European actions and networks such as ENDURE were made. The main interest of the study is the method used, based on value chain, but improved to encompass the whole complexity of the innovation process by integrating technological/scientific elements as well as sociological, economic or organizational aspects. The main conclusions of this study confirmed that a complex approach combining technological and social aspects is essential to understand and manage the innovation process. Some specificities of ICT innovation in agriculture, especially in this for crop protection, were highlighted at several levels (economical, social and technological). This first experiment on this methodology also pointed out new directions of research on innovation.}, }

One of the main challenges for today's agriculture is to increase drastically the production while at the same time being more sustainable. Innovation is seen in Europe as the key solution and ICT have a great potential to boost innovation in agriculture. As the complexity of the innovation process still remains difficult to manage, an experimental Public-Private Partnerships Action of the ICT AGRI Era-net was launched and is presented in this paper. This one-year action aimed to gather together all the players involved at the European level for crop protection and to boost concrete innovation in ICT to reduce the use of pesticides, especially around a unified platform of information and services. The main conclusions of this study, especially on the method tested, are presented in this paper and some recommandations are made for next innovation management actions.

Integrating continuous spatial data into SOLAP systems is a new research challenge. Moreover, representation of field data at different scales or resolutions is often mandatory for an effective analysis. Thus, in this paper, we propose a logical model to integrate spatial dimensions representing incomplete field data at different resolutions in a classical SOLAP architecture.

This paper presents the progress made in the prototyping of a Crop Model Factory. This method is intended to be used by agronomists to design scientific models and to produce the corresponding Java code to be used in a web-based decision support system. A subpart of a legacy vine model is used throughout the paper to illustrate the advances of the prototyping phase. Note that the version of the prototype presented in our previous papers was very basic. The new software version described here includes numerous fully functional components (e.g., new graphical user interface, model serialization) and provides Java code generation. The present paper focuses only on these new elements.

Extension of the Semantic Sensor Network Ontology for Wireless Sensor Networks: The Stimulus-WSNnode-Communication Pattern

Wireless Sensor Networks (WSN) are designed to collect large amounts of heterogeneous data to monitor environmental phenomenon. Our aim is to adapt WSN nodes communication to their context, in order to optimize the lifetime of the network. Our description of context and WSN characteristics are based on ontologies. Based upon a critical analysis of existing ontologies which formalize the WSN domain, we determine that the Semantic Sensor Network (SSN) ontology is the most suitable to represent the WSN issues. However, as the communication data policy is not characterized either by SSN or by other ontologies, we propose to enrich the SSN ontology with a new pattern describing communication. In this paper, we will ﬁrst integrate the different concepts related to WSN in the SSN ontology and then we will use the resulting ontology, called Wireless Semantic Sensor Network ontology, in an agri-environmental scenario to illustrate the interest of our approach.

Definition and analysis of new agricultural farm energetic indicators using spatial OLAP
International Conference on Geographical Analysis, Urban Modeling, Spatial Statistics, 18/05/2012-20/05/2012, Salvador de Bahia, BRA (p. 14), 2012
abs web bib

Agricultural energy consumption is an important environmental and social issue. Several diagnoses have been proposed to define indicators for analyzing energy consumption at large scale of agricultural farm activities (year, farm, family of production, etc.). However, to define ad-hoc environmental energetic policies to better monitor and control energy consumption, new indicators at a most detailed scale are needed. Moreover, by defining detailed scale indicators, large quantities of geo-referenced data need to be collected to feed these energetic diagnoses. This huge volume of data represents another important limitation of systems that implement these diagnoses because they are usually based on classical data storage systems (such as spreadsheet tools and Database Management Systems). These systems do not allow for interactive analysis at different granularities/scales of huge volumes of data and do not provide any cartographic representation. By contrast, Spatial OLAP (SOLAP) and spatial data warehouse (SDW) systems allow for the analysis of huge volumes of geo-referenced data by providing aggregated numerical values visualized by means of interactive tabular, graphical and cartographic displays. Thus, in this paper, we (i) propose new appropriate indicators to analyze agricultural farm energy performance at a detailed scale and (ii) show how SDW and SOLAP technologies can be used to represent, store and analyze these indicators by simultaneously producing expressive reports.

New conceptual modeling requirements for stream data warehouses

Spatial data warehouses (SDW) and Spatial OLAP (SOLAP) systems allow the storage and multidimensional analysis of huge volumes of geographic data. Existing SOLAP models do not take into account connectivity of spatial objects and consequently they do not natively integrate networks. In this paper, we propose a UML (Unified Modeling Language) profile for SDW integrating spatial networks. We implemented our UML profile using UML meta-model elements and OCL (Object Constraint Language) constraints with a Computer-Aided Software Engineering tool (MagicDraw). The implementation of the conceptual model in a database is presented using Oracle. / Les entrepôts de données spatiales (EDS) et les outils OLAP spatial (SOLAP) permettent le stockage et l'analyse multidimensionnelle d’une grande quantité de données géographiques. Les modèles existants SOLAP ne tiennent pas compte de la connectivité des objets spatiaux et par conséquent ils n’intègrent pas les données de type réseaux, comme les réseaux routiers et leurs méthodes d'analyse. Dans cet article, nous proposons un profil UML (Unified Modeling Language) pour les entrepôts de données intégrant des réseaux spatiaux. Nous mettons en oeuvre notre profil UML en se basant sur le méta-modèle d’UML et des contraintes OCL (Object Constraint Language) avec un atelier de génie logiciel (MagicDraw).

Spatial Data warehouses and Spatial OLAP systems are Business Intelligence technologies allowing efficient and interactive analysis of large geo-referenced datasets. In such a kind of systems the goodness of analysis depends on: The warehoused data quality, how aggregations are performed, and how warehoused data are explored. In this paper, we propose a framework based on a UML profile and OCL-defined integrity constraints to grant quality in the whole SOLAP system. We also propose an automatic implementation in a classical ROLAP architecture to validate our proposal.

Les entrepôts de données spatiales et les systèmes Spatial OLAP sont des technologies d’aide à la décision permettant l’analyse en ligne des gros jeux de données géo-référencées. Dans un tel type de systèmes, la qualité de l’analyse dépend : de la qualité des données entreposées, de comment les agrégations sont effectuées, et de comment les données entreposées sont explorées. Dans cet article, nous proposons une méthode pour garantir la qualité de ces trois facteurs, fondée sur un profil UML et sur des contraintes d’intégrité définies avec Spatial OCL.

Classification de documents combinant la structure et le contenu

Developing the text processing applications has revolutionized the world of documents. The author constructs the document as structured document in which the textual content is organized around tags. However, the traditional document classification typically classifies the documents considering the text and ignoring its structural elements. In this paper, we propose a representation method which makes use of structural elements to create the vector of tag and word weighted by an extension of TF-IDF and TF-IEF formula. This representation is constructed from an aggregated tree of XML document. Several experimentations have been made using SVMlight as classifier on Reuters and INEX collections. / La démocratisation et l’évolution des logiciels de traitements de texte ont révolutionné le monde du document. Les auteurs construisent des documents dits structurés c'est-à-dire dont le contenu textuel s’organise autours de balises. Toutefois, la classification traditionnelle de documents n’utilise que le contenu textuel des documents et ignore les informations de structure. Dans ce papier, nous proposons une nouvelle représentation des documents structurés basée sur un vecteur pondéré associant un mot et une balise. Les poids sont calculés en adaptant les formules TF-IDF et TF-IEF. Cette représentation est construite à partir d’une représentation synthétique du document appelé arbre résumé. Pour évaluer notre approche, nous avons mené plusieurs expérimentations avec un système de classification basé sur le classifieur SVMlight. Nous présentons les résultats de nos expérimentations menées sur les corpus REUTERS et INEX.

The routing protocol for low power and lossy network (RPL) was designed in the ROLL working group at IETF since the year of 2008. Until the latest version of draft 19 released, this protocol algorithms and its four application scenario, such as home automation, industrial control, urban environment and building automation, have been nearly grounded. However, it is still very difficult to find effective approaches to simulate and evaluate RPL’s behavior and other extensions of its application. In this paper, first we provide a brief presentation of the RPL protocol including two case studies ContikiRPL and TinyRPL, and an initial simulation experiment results obtained from the RPL capable COOJA simulator and its developed module. Second we then focus on the utilization of this protocol in the precision agriculture area and propose our dedicated instances hybrid network architecture to meet the specific requirement of this application. As a conclusion, we summarized our ongoing work and future solutions of the current technology issues.

The wireless sensor network (WSN) is one of the most important technologies of the 21st century. Most researchers and technical analysts believe that in the near future, these micro-sensors will be integrated throughout anywhere of our life. In recent years, the IoT (Internet of Things) and WoT (Web of Things) technologies also have great forwarding. Especially, the IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) protocol has allowed the use of IPv6 protocol stack in the field of WSN, thanks to its encapsulation and compression mechanisms in IPv6 packet header. Moreover, the RPL (IPv6 routing protocol for low-power and lossy network) provides such a powerful routing function that can be applied for a variety of application scenario. These two key standards of IoT and WoT technologies for WSN can be used in an IPv6 stack, and they will successfully achieve the connection between Internet and micro-sensors. Thus, due to the availability of IPv6 address (128-bit), all the communicating objects, such as smart device, sensor, actuator and etc., can be connected to the Internet. That is the greatest advantage brought by the IoT. Although the advancement of these techniques is extremely fast, several issues caused by resource constraints of micro-sensor (limited processing power, bandwidth and lossy connection link, and energy), such as QoS, energy efficient, robustness and lifetime of WSN, and the most important, the special requirement brought by agricultural applications, are still very challenging and waiting to be solved.

Outil SANBA : capitalisation des connaissances et retour d'expérience sur les barrages et leur sécurité

Knowledge related to dam design, construction and failure and degradation modes are numerous, scattered and not explicit for some of them. Consequently, it is interesting to develop tools that allow gathering, capitalizing and making explicit current and future knowledge. These tools can constitute learning or documentation support systems. We present, in this article, the prototype tool SANBA composed of a knowledge basis, SANBA-dom, more particularly centered on the dam design, construction and failure and degradation modes (domain knowledge) coupled with a case basis, SANBA-cas, that describes in a detailed way incidents and accidents that occurred on works (diagnosis, consequences and corrective actions). The method relies on 4 main stages: determination of the study granularity, identification and structuring of fields, implementation of a computer tool and instantiation. Validations are carried out after the identification and instantiation stages. Two different technologies were used for the 2 components of SANBA tool: SANBA-cas component is implemented using Symfony (framework PHP open-source) and SANBA-dom using a Wiki technology. The use of Web technologies allows making more accessible the formalized knowledge and simplifying their capture. These bases are currently on filling and validation, at Irstea Aix-en-Provence. They will be later accessible to an external public for consulting and writing tasks in function of the rights conferred to each type of user. / Les connaissances sur la conception-réalisation et les modes de rupture et dégradation des barrages sont nombreuses, dispersées et non explicites pour certaines. Il est donc intéressant de développer des outils permettant de rassembler, capitaliser et expliciter les connaissances actuelles et futures et de constituer des supports de formation ou de documentation. Nous présentons, dans cet article, l'outil prototype SANBA composé d'une base de connaissances, SANBA-dom, axée plus particulièrement sur leur conception et réalisation et sur leurs modes de rupture et de dégradation (connaissances du domaine) couplée à une base de cas, SANBA-cas, décrivant de manière détaillée des incidents et accidents s'étant produits sur des ouvrages (diagnostic, conséquences et actions correctives). La démarche repose sur 4 grandes étapes : détermination de la granularité de travail, identification et structuration des champs, implémentation d’un outil informatique, instanciation. Des validations sont réalisées après l’étape d’identification des champs et d’instanciation. Deux technologies différentes ont été utilisées pour chacune des composantes de l'outil SANBA : la composante SANBA-cas utilise une implémentation sous Symfony (framework PHP open-source) et la composante SANBA-dom une technologie Wiki. L’utilisation de technologies Web permet de rendre facilement accessibles les connaissances formalisées et de simplifier leur saisie. Ces bases sont en cours de remplissage et de validation, actuellement en interne au sein d’Irstea Aix-en-Provence, puis seront ensuite accessibles à un public extérieur à des fins de lecture et d’écriture selon les droits conférés à chaque type d’utilisateur.

The purpose of our work is to analyze different harvesting solutions in different situations in order to provide players of the sugarcane sector viable solutions in the context of Réunion island. Two sugarcane harvesters, with different technologies have been instrumented in order to trace the various phases of work and better understand the operating conditions of machines in collective management. The embedded sensors could discriminate and localize the various stages of the harvest operations. The data collected were stored in a data logger on the machine and could be downloaded via a GPRS connection to a server. Data were daily recorded on the machine throughout the harvesting campaign (5 months). Once the data acquired, their processing with the R software and their linkage with other data (i.e. economic) collected during the harvest campaign give us different information that are integrated in a GIS. With the developed tools, we can produce references at different spatiotemporal scales: Parcels, production areas, daily, annually.

Cost models for view materialization in the cloud
DANAC, 30/03/2012-30/03/2012, Berlin, DEU (p. 8), 2012
abs web bib

In classical databases, query performance is casually achieved through physical data structures such as caches, indexes and materialized views. In this context, many cost models help select a "best set" of such data structures. However, this selection task becomes more complex in the cloud. The criterion to optimize is indeed at least two-dimensional, with the monetary cost of using the cloud balancing query response time. Thus, we define in this paper new cost models that fit into the pay-as-you-go paradigm of cloud computing. These cost models help achieve a multi-criteria optimization of the view materialization vs. CPU power consumption problem, under budget constraints. Finally, we present experimental results that provide a first validation of our contribution and show that cloud view materialization is always desirable.

Ontology antipatterns are structures that reflect ontology modelling problems, they lead to inconsistencies, bad reasoning performance or bad formalisation of domain knowledge. Antipatterns normally appear in ontologies developed by those who are not experts in ontology engineering. Based on our experience in ontology design, we have created a catalogue of such antipatterns in the past, and in this paper we describe how we can use SPARQL-DL to detect them. We conduct some experiments to detect them in a large OWL ontology corpus obtained from the Watson ontology search portal. Our results show that each antipattern needs a specialised detection method.

Ontology antipatterns are structures that reflect ontology modelling problems because they lead to inconsistencies, bad reasoning performance or bad formalisation of domain knowledge. We propose four methods for the detection of antipatterns using SPARQL queries. Based on our experience in ontology design, we focus our study on four antipatterns described in the litterature.These antipatterns widely appear in ontologies developed by those who are not experts in ontology engineering. We conduct some experiments to detect them in a large OWL ontology corpus obtained from the Watson ontology search portal. Our results show that none of the detection methods works well on the four antipatterns, and that hence each antipattern needs a specialised detection method.

We propose four methods for the detection of antipatterns using SPARQL queries. Based on our experience in ontology design, we focus our study on four antipatterns described in the litterature.These antipatterns widely appear in ontologies developed by those who are not experts in ontology engineering. We conduct some experiments to detect them in a large OWL ontology corpus obtained from the Watson ontology search portal. Our results show that none of the detection methods works well on the four antipatterns, and that hence each antipattern needs a specialised detection method.}, }

A knowledge server for sustainable agriculture: Main computing features
8th International Conference on Web Information Systems and Technologies , 18/04/2012-21/04/2012, Porto , PRT (p. 6), 2012
abs web bib

Agriculture must evolve into a more environmentally-friendly approach, while remaining economically viable and socially interesting, which is necessary so that the process can be pursued in the long term, i.e that the process is sustainable (Brundtland 1987). Sustainable agriculture has a systemic logic and therefore requires a strong knowledge base. In this study, we propose a knowledge management computing tool. In the first part of our article, we discuss the potential actors of the tool and their possible implications. The second part deals with its contents. In the third part, the main computing features of the tool are shown.

MDE in action: First steps towards a crop model factory

In an industrial context of web-based decision support system for croppers, agronomists in our firm design crop models using a scientific programming language. Then in a second step this model is transposed in Java by computer engineers. Due to keeping both codes in evolution, this double implementation causes losses in cost production. To avoid such costs, this paper proposes to apply model driven engineering techniques to identify a metamodel for the domain of mechanistic modelling in agronomy. We started by a reverse engineering of three existing model implementations. The resulting metamodel is the basis for the definition of a mechanistic model factory dedicated to agronomists. This visual tool will offer automatic model linking and data conversion features: they rely on the definition of metadata associated with the inputs/outputs of the different models and on the use of adapters. These automation possibilities should grant easy design capabilities and optimal model reuse in the future. The designed models are linked to the metamodel proposed thus permitting the generation of a ready-to-use Java implementation of the mechanistic model.

In the coming years, the agricultural sector will face many challenges : increase production to cope with the population growth, increase the quality to meet consumer demand, preserve natural resources and biodiversity, and be economically viable for all players. This requires many changes, some of which will be made possible or facilitated by the digital revolution : Internet of Things, Big Data, artificial intelligence... The decision process will be able to mobilize a lot of data from multiple sources and to apprehend in its global agricultural context. My research is part of the development of digital agriculture. The research presented in this thesis is focused on the acquisition of agri-environmental data from wireless sensor networks. Their main objectives were to ensure proper operation of the networks and reliability allowing to have relevant data for decision making. Contextualization of the network operation and data enables adaptation to various stresses to the system : environmental, energy, quality... The context-aware approach has naturally directed research towards ontologies and integration of knowledge in systems for better management of information and data in the service of sustainable agriculture. / Dans les prochaines années, les filières agricoles devront relever de nombreux défis : accroitre la production pour faire face à la croissance de la population, augmenter la qualité pour répondre à la demande des consommateurs, préserver les ressources naturelles et la biodiversité, et être économiquement viable pour l’ensemble des acteurs. Cela nécessite de nombreuses mutations dont certaines seront rendues possibles ou facilitées par la révolution numérique : Internet des Objets, Big Data, intelligence artificielle... Les processus de décision devront pouvoir mobiliser de nombreuses données issues de multiples sources et permettant d'appréhender dans sa globalité le contexte agricole. Mes recherches s’inscrivent dans ce développement de l’agriculture numérique. Les travaux de recherche présentés dans ce mémoire se sont focalisés sur l’acquisition de données agri-environnementales par des réseaux de capteurs sans fil. Leurs principaux objectifs étaient d’assurer un bon fonctionnement des réseaux et une fiabilité permettant d’avoir des données pertinentes en vue de la prise de décision. La contextualisation du fonctionnement des réseaux et des données permet une adaptation aux différentes contraintes subies par le système : environnementales, énergétiques, qualité... La modélisation de contexte a tout naturellement orienté les recherches vers les ontologies et l’intégration de connaissances dans les systèmes pour une meilleure gestion de l’information et des données au service d’une agriculture durable.

Entreposage et analyse en ligne des données spatiales : application aux données agro-environnementales
2015
abs web bib

Il a été estimé qu'environ 80% des données stockées dans les bases de données transactionnelles intègrent l'information géographique[12]. Les entrepôts de données spatiales (EDSs) et le Spatial OLAP (SOLAP) permettent d'analyser d'énormes volumes de données géoréférencées [1] [11]. Le SOLAP a été appliqué avec succès dans plusieurs domaines tels que le marketing, la santé [2], l'urbanisme, etc. Le succès des technologies SOLAP est principalement basé sur les capacités de ces systèmes à analyser de grandes bases de données de manière interactive, et de les présenter via des interfaces d'analyse visuelle simples et utilisables [2]. Dans ce mémoire, via une étude approfondie des travaux portants sur l'analyse SOLAP des données agro-environnementales (Chapitre 2), nous décrivons les principales questions de recherche liées à l'analyse multidimensionnelle des données agro-environnementales, en soulignant les questions théoriques et d’implémentation. Pour remédier à ces problèmes, nous avons proposé un nouveau cadre pour l'intégration et l’analyse des données agro-environnementales dans les systèmes SOLAP. En particulier, notre cadre proposition prend en charge la modélisation conceptuelle des données spatio-multidimensionnelles vectorielles (Chapitre 3) et continues (Chapitre 4), et la gestion des problèmes de qualité liés à la précision spatiale des données (Chapitre 5) et la cohérence logique. Deuxièmement, nous proposons une architecture SOLAP générique pour faire face à certains problèmes d’implémentation (intégration, entreposage, analyse et géovisualisation). Enfin, pour prendre en compte les compétences des décideurs agro-environnementales, et la complexité de ces applications, nous avons proposé une méthodologie de prototypage rapide basée sur notre modèle conceptuel.

Etude et analyse de l'opportunité d'utiliser des tracteurs électriques en viticulture
2016
abs web bib

Etude et analyse de l’opportunité d’utiliser des tracteurs électriques dans le contexte viticole Champenois étant donné déjà la présence du tracteur électrique T4E de la société Kremer Energie sur les exploitations des sites de Bouzy et Hauvillers de la société MHCS. Cette étude a été conduite en partenariat avec l’Agence de Clermont-Ferrand de la société SEGULA ENGINNEERING & CONSULTING pour son expertise en architecture des véhicules électriques et l’équipe de VetaAgro Sup membre de l’UMR METAFORT de Clermont-Ferrand pour ses compétences liées à la partie économique. L’usage du tracteur électrique a été évalué avec différents acteurs intervenant dans le développement et l’usage de ces technologies, notamment des conducteurs et des responsables. Des mesures spécifiques ont été mise en ½uvre sur le site de Bouzy avec l’utilisation de deux tracteurs enjambeurs et de leur équipement de pulvérisation pour obtenir et vérifier certaines caractéristiques techniques de chacun des tracteurs utilisés. Des mesures lors de parcours effectués au milieu des vignes ont permis une évaluation de la consommation énergétique et une approche des autonomies énergétiques. Des mesures d’effort de traction ont été effectuées sur sol dur et sur chemin de terre dans les vignes et ont été complétées par des mesures de bruits et de vibrations. Les données obtenues ont permis ensuite d’être utilisées pour compléter l’analyse technico-économique effectuée.

Etude de faisabilité de la mesure du rendement d'une récolte de maïs grain en épis sur un corn-picker Bourgoin
2016
abs web bib

La mesure des rendements du maïs semence récolté en épis avec un corn-picker n’est à l’heure actuelle possible que globalement à postériori soit par pesée avec un équipement disponible à la parcelle ou soit avec la pesée de la benne réceptrice pour chaque récolte de variété différente. Sur un corn-picker les quantités récoltées pourraient, soit être globalement obtenues pour chaque parcelle récoltée à l’aide d’une pesée embarquée ou soit mesurées en temps réel lors de la récolte de façon similaire au principe adopté sur une moissonneuse batteuse. Compte tenu de ces différents éléments et observations recueillis, dans un premier temps cette étude a été réalisée pour tenter d’approcher les différentes solutions envisageables à partir d’un état de l’art des solutions existantes pour d’autres applications du secteur agricole mais également dans d’autres secteurs d’activités et qui pourraient être aussi utilisées pour mesurer le rendement des récoltes de maïs grain en épis sur un corn-picker. Ces éléments ont été complétés avec les observations recueillies sur deux types de corn-pickers en conditions réelles de travail sur plusieurs chantiers de récolte complétés de diverses informations recueillies auprès des utilisateurs ou des intervenants de la filière au cours de la campagne de récolte 2015.

The objective of this study is to improve the software OASIS, tool for water withdrawal. The use of a tool is based on its usefulness and its ease of use. It must therefore be built with these two milestones in perspective. To better understand these two points, a survey was conducted in several departments to understand needs of the state services as well as the digital environment of the Oasis software with other tools "police water" of the Ministry of ecology and the tools of the agencies of the water, BRGM and Onema. / L’objectif de cette étude est d’améliorer le logiciel OASIS, outil police de l'eau pour l’instruction technique et juridique de prélèvement des eaux, en cours de développement.

Rapport sur les technologies SOLAP récentes
2012
abs web bib

L’objectif de cette étude réalisée pour la société Agaetis est de faire un point sur les récentes technologies SOLAP. Il s’agissait après avoir résumé les principes du SOLAP, de faire le tour des principaux outils proposés actuellement : repérer les prototypes de recherche et surtout tester les solutions opérationnelles. Nous avons aussi donné les tendances du domaine que l’on voit apparaître dans les derniers sujets de recherche, tout en donnant notre analyse sur les limites actuelles de la technologie SOLAP. Nous présenterons sous la forme de reviews, le résultat de nos tests de 11 solutions SOLAP (ou presque SOLAP).

Rapport technique Projet DISP'eau du 1er mars 2010 au 31 mai 2011
2011
abs web bib

L'objectif principal du projet DISP'eau est l'élaboration, dans le cadre de la viticulture, d'un outil d'aide à la décision (OAD) relatif à la gestion de la ressource en eau. Cet outil doit notamment intégrer des scénarios où intervient l'irrigation pour les cas où celle-ci est autorisée. Pour ce faire, cet outil utilise des modèles qu'il faut alimenter avec différents types de données. Une partie de celles-ci sont fournies par une plate-forme de collecte automatique des données développée par le Cemagref. Le rapport technique suivant présente les travaux réalisés jusqu'à aujourd'hui au niveau de cette plate-forme.
