OOML-Based Ontologies and Its Services for Information Retrieval in UDMGrid

摘要

In order to effectively integrate and share the enormous dispersed resources of various digital museums, University Digital Museum Grid (UDMGrid) has been developed to provide one-stop information services about kinds of digital specimens in the form of grid services. To eliminate the heterogeneity between the information resources, shared concepts for these digital museums are indispensable. This paper studies OOML-based ontologies and its services for information retrieval in UDMGrid, including the object oriented ontology construction and ontology mapping, in which a novel inheritance mechanism is proposed to eliminate logic confusion. On the basis of OOML-based ontologies, ontology services are developed to assist the information retrieval by transforming global concepts to local concepts.
