A Semantic analysis of moving objects, using as a case study maritime voyages from eighteenth and nineteenth centuries
2014
International audience; In this paper, we present a spatial model designed to extract knowledge from the tracks of moving objects. The model uses a perdurantism approach, implemented using Semantic Web technologies. In order to show the capabilities of the model, we employ it to handle a large dataset composed of historic maritime records. By using Semantic Web tools, we are able to implement rules and identify user defined patterns. Although there are limitations due to currently available tools, our results are promising.
Continuum : un modèle spatio-temporel et sémantique pour la découverte de phénomènes dynamiques au sein d’environnements géospatiaux
2015
There is a need for decision-makers to be provided with both an overview of existing knowledge, and information which is as complete and up-to-date as possible on changes in certain features of the biosphere. Another objective is to bring together all the many attempts which have been made over the years at various levels (international, Community, national and regional) to obtain more information on the environment and the way it is changing. As a result, remote sensing tools monitor large amount of land cover informations enabling study of dynamic processes. However the size of the dataset require new tools to identify pattern and extract knowledge. We propose a model to discover knowledg…
Using Semantic Web Technologies to Follow the Evolution of Entities in Time and Space
2013
International audience; In this paper we present the "continuum model". Our work follows a "perdurantism" approach and is designed to handle dynamic phenomena extending the 4D-fluent with the use of semantic web technologies. In our approach we represent dynamic entities as constituted by timeslices each with semantic, geometric, temporal and identity components. Our model is able to link the diverse representations of an entity and allows the inference of qualitative information from quantitative one. The inference results are later added to the ontology in order to improve knowledge about the phenomenon. The model has been implemented using OWL and SWRL. Our preliminary results are promis…
un modèle sémantique spatio-temporel pour capturer la dynamique des environnements
2014
National audience; Les Systèmes d'Information Géographique se sont peu à peu imposés comme des outils performants pour organiser, représenter, analyser et visualiser des données géographiques. Toutefois, l'intégration d'une dimension temporelle dans les SIG reste un défi de la recherche en sciences de l'information géographique. Dès lors, le développement de modèles spatio-temporels adaptés à l'étude de phénomènes géographiques réels devient un enjeu majeur dans la conception de systèmes d'informations dédiés à l'évolution d'entités spatiales. Dans ces travaux, nous proposons un nouveau modèle spatio-temporel basé sur une ontologie intégrant les connaissances des experts sur les données géo…
