OSIRIS - Un outil d'annotation et de recherche sémantique de ressources multimédia fondé sur les Graphes Conceptuels

OSIRIS is a technological platform dedicated to the development of Ontologybased System for Semantic Information Retrieval and Indexation of multimedia resources which are shared within communautary and open web Spaces. Based on the use of both heavyweight ontologies and thesaurii, OSIRIS allows the end-user (1) to describe the semantic content of its resources by using an intuitive model of annotation which is founded on the triple (Subject, Verb, Object), and (2) to formally represent these annotations by using Conceptual Graphs. Moreover, each resource can be described by adopting multiple points of view. These different points of view can also be defined by using multiple ontologies which can be related to connected (or not-connected) domains. Developed from the integration of Semantic Web technologies and Web 2.0 technologies, OSIRIS aims at facilitating the deployment of semantic, communautary and open web spaces. MOTS-CLÉS : ontologie, thésaurus, annotation, recherche d’information, graphes conceptuels, webs sémantiques communautaires, multimédia.
