基于本体的XML数据源语义集成研究

Study of Ontology-based Semantic Integration of XML Data Sources

提议了一个基于本体的XML数据源语义集成方法,为每个参与集成的XML文档产生一个局部RDF本体,合并局部本体的结果产生一个全局本体.全局本体统一查询访问并在后台局部XML数据源之间建立语义关系,在全局本体上的查询通过从RDF查询到XML查询的转换被处理.

An approach of ontology-based semantic integration of XML data sources is provided, which generates a local RDF ontology for each of the participating XML documents. A global RDF ontology is the result of merging the local ontologies. The global ontology unifies the query access and establishes semantic connections among the underlying local XML data sources. The query on global ontology is processed using query translation from an RDF query to an XML query.
