Research on Heterogeneous Data Sharing Based on Ontology
The traditional method of heterogeneous data sharing can not describe the formal semantics of data and finds it difficult to solve the semantic heterogeneity in the heterogeneous information sharing.Based on the XML-based heterogeneous data integration technology,the heterogeneous data sharing method is proposed based on ontology by introducing metadata and ontology.By metadatas specifying the distributed,heterogeneous data and by describing semantic information of data source,having ontology as a common semantic model,semantic match is established through ontology mapping between heterogeneous data sources and semantic difference institutions are shielded,so that semantic heterogeneity problem of the heterogeneous data sources can be effectively solved.Experiments show that the method can solve the problem of semantic heterogeneity of heterogeneous data.
