Enhancing Service Discovery via Multi-Ontology Management and Annotation

Ontology, which adds semantic information to services, is an effective tool to automatize service discovery and composition. Though service discovery systems have been developed extensively, most possible scenario would still be that all the services adhere to a single ontology. However, even in a same domain, different domain experts or users can conceptualize the same real world entities in different views which will lead to multiple domain ontologies. Therefore how to manage multi-ontology and then how to use them to annotate service are the key technologies in service discovery system. In this paper based on ISO SC32 19763-3: MFI-3 (Metamodel Framework for Interoperability: Metamodel for Ontology Registration) we discuss in detail the mechanism of multi-ontology management and annotation to enhance the service discovery. Finally a prototype of Ontology Management Platform (OMP) is realized to serves annotation.
