Appropriate global ontology construction
Cheikh Niang, Béatrice Bouchou, Moussa Lô, Yacine Sam · 2011
Data integration involves combining data residing in different sources and providing users with a unified view of these data through what is called a "global schema". We address here the problem of automatic construction of this global schema in the semantic Web context, where data sources are annotated with ontologies. We aim in other words to automatically build a common vocabulary (ontology) that will serve as a shared conceptual level for several heterogeneous data sources needing to share their data in a specific application domain. We propose a solution based on the use of a domain reference ontology (or "background knowledge") as a mediation support.
