Abstract：A method for integrating distributed heterogeneous data is proposed. The data query processing is implemented by issuing and registering data services actively in an unit for all network nodes, called data service cell (DS-Cell). Then the data services are retrieved by an intelligent matcher. By effectively interfusing the techniques of semantic web, web ontology language (OWL), and description logic, the proposed method can work with data formal semantics and ontology based reasoning. A prototype of data integration system is designed based on the proposed method, and the experimental tests on the core component of the system are conducted. The experimental results show that the proposed system works effectively and reliably with favorable flexibility, scalability and performance.
