A On-Demand Mapping Method on Query Request in Relational Database Semantic Query

Abstract:

Relational database semantic query namely RDF access to relational database is an important issue in semantic Web research. To realize the query is to build mapping relation between relational database schema and ontology. However, there is natural isomerism between them. The isomerism can be eliminated by transforming relational database schema into similar ontology and then building mapping between conversion ontology and input ontology. This paper realized an ondemanding mapping method when users request query, avoided building all concepts and attributes mapping between conversion ontology and input ontology and improved mapping efficiency.
