Using semantics to improve schema and data integration

Mokrane Bouzeghoub

Most of the work done on schema integration and data integration is based on equivalence assertions established by the user or the designer and used within merge/match algorithms. These assertions mainly concern equivalent of terms in schema integration and closeness of values in data integration. This presentation shows how both integrations have evolved from a syntactic approach to a more semantic approach, using particularly linguistic knowledge and ontologies. We show how in both cases integration assertions can be automatically discovered using this knowledge. Clique no link abaixo para buscar o texto completo deste trabalho na Web: Buscar na Web
