Le developpement rapide du Web semantique est lie a la specification de plus en plus d'ontologies. Celles-ci permettent de modeliser des connaissances agreees par des communautes de personnes concernant des domaines ou des tâches specifiques. Le meme domaine decrit par deux communautes distinctes sera modelise de facon differente. Les systemes cooperatifs visent a rendre les informations provenant de differentes sources disponibles au-dela de leurs divergences. Pour cela, ils doivent aligner, fusionner ou integrer ces ontologies. La decouverte de mappings est un point cle dans la resolution efficace des heterogeneites entre ontologies. Nous developpons une architecture qui connecte des systemes d'information via des ontologies, avec comme objectif la resolution de requetes complexes. Le but de notre article est de decrire les grandes lignes de cette architecture, apres avoir presente la methodologie utilisee pour mettre en correspondance les diverses ontologies rencontrees. The rapid development of the semantic Web is associated with the specification of various ontologies which formally represent agreements of communities of people on specific domains or tasks. The same knowledge formalized by different people leads to heterogeneous representations. Cooperative systems, which aim to make knowledge from various sources available in spite of their heterogeneities, need to align, merge or integrate the ontologies used to model the information sources. Furthermore, the resolution of differences among ontologies is necessary to process queries or use web services in distributed heterogeneous environments. Mapping discovery is a key issue to allow efficient resolution of heterogeneity. We develop an architecture for mapping different systems associated with ontologies. In this paper we present the key components and the underlying concepts of a framework and approach for comparing and matching different ontologies.
