Ontology Integration and Application of Relational Databases

Hongzhe Liu

Abstract

Ontology is used more and more for the integration of heterogeneous information sources.In general,there are three different directions for ontology integration: single ontology approach,multi ontology approach and hybrid ontology approach.In the paper,an integration framework based on hybrid ontology approach is proposed.The approach supports two types of queries: queries posed on global ontology and those posed on local data sources.How the two types of queries are implemented is discussed in details.In addition,the implementation of the framework in distributed museums proves efficient.
