Similarity estimation module for OWSCIS
2008
Semantic interoperability based on ontologies is nowadays becoming a great challenge. We propose an architecture for semantic-based cooperation called OWSCIS (Ontology and Web Service based Cooperation of Information Sources). It allows to map various information sources using ontologies and to answer users' queries over the cooperation. In this paper we focus on the similarity estimation service of the OWSCIS Architecture which allows to discover mappings between different ontologies. It relies on various mappings methods which are combined and refined to semi-automatically generate mappings between a local and a reference ontologies.
Ontology mapping specification in description logics for cooperative systems
2006
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 syst…
