Enrichissement de requêtes et visualisation sémantique dans une coopération de systèmes d'information : méthodes et outils d'aide à la recherche d'information

Abstract : This thesis presents approaches and tools for information retrieval. Our work is part of a cooperation system based on ontologies called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). We treat the problem of information retrieval by providing an enrichment method called QUEXME (QUery EXpansion MEthod) of queries based on analysis of user behavior and using the concept importance notion with regards to query. We also discussed the problem of visualization in the OWSCIS system offering a architecture of service visualization. It is composed of three modules: the request, enrichment and results. The approaches proposed in this thesis have been prototyped and the testing of the QUEXME method was performed using the information base (ontology) developed in the Euro-Mediterranean Information System on know-how in the Water sector (EMWIS).
