Abstract

Our objective is to automatically build a global ontology from several data sources, annotated with local ontologies and aiming to share their data in a specific application domain. The originality of our proposal lies in the use of a background knowledge, i.e. a reference ontology, as a mediation support for data integration. We represent ontologies using Description Logics and we combine syntactic-matching with logical-reasoning in order to build the shared global TBox from both the TBoxes of sources and that of the reference ontology.
