Semantically enriched informed environment for multi-agent simulation : application to simulation in 3D virtual environment
2014
This thesis focuses on multi-agent simulation applied to the simulation of individuals in virtual 3D buildings. To do this, our work suggests to capitalize on the experience gained in the field of semantic web ontologies and inference engines to facilitate the design and development of intelligent behavior for agents operating in virtual worlds. The goal is to provide to agents a generic approach to managing their representation of the world and reason about this representation. For this, the central problem is based on the definition of a decidable ontology modeling all of the knowledge contained in the virtual 3D environment to enrich semantically the environment of a multi-agent simulati…
Implementing a Semantic Catalogue of Geospatial Data.
2014
International audience; Complex spatial analysis requires the combination of heterogeneous datasets. However the identification of a dataset of interest is not a trivial task. Users need to review metadata records in order to select the most suitable datasets. We propose the implementation of a system for metadata management based on semantic web technologies. Our implementation helps the user with the selection task. In this paper, we present a CSW that uses a triplestore as its metadata repository. We implement a translator between Filter Encoding and SPARQL/GeoSPARQL in order to comply to basic OGC standards. Our results are promising however, this is a novel field with room for improvem…
