Abstract: In this paper, we present a new approach to merge OWL ontologies by semantic enrichment of initial ontologies. This work is situated in the general context of stored information heterogeneity in a decisional system such as data, metadata and knowledge, for combination and reconciliation these forms of information by mediation. To add a semantic dimension to the merger, our approach based on semantic enrichment of initial ontologies, this is achieved by enriching initial ontologies by a set of metadata that annotate their concepts with synonyms and homonyms for each concept, via the use of WordNet, or semantic enrichment of an expert, then it generates a thesaurus for each local ontology to build the global thesaurus. Our method focuses on computing semantic similarity between concepts of ontologies, and based on a weighted combination of computing similarity methods, we use syntactic, lexical, structural and semantic techniques, for generating the correspondence matrix; from this latter we generate the merged ontology.

Keywords: merging ontologies; taxonomy; similarity measures; semantics; metadata; mapping; OWL ontologies; semantic enrichment; semantic similarity; ontology concepts.
