Abstract:
Mapping between ontologies is the major bottleneck in semantic integration. In this paper, we present MCMA, a mediator-centric mapping architecture that facilitates the integration between ontologies of interrelated companies. In MCMA, different ontologies are mapped through some middle concepts and the Mapping Service acts as a bridge to connect them. As a mediator, the provider of Mapping Service is interested in a specific area and offers some common ontologies for participators to reuse. On the assumption that each individual ontology may reuse or make reference to common definitions, some mapping relations can be defined conveniently. Based on these basic mapping relations, the Mapping Service infers more middle-concept oriented mapping relations and organizes them in a layered manner. We present the idea of combining heuristics or machine-learning techniques with common ontology approach in the mapping discovery.
