Abstract:

Aimed at data integration in a larger extent,an ontologybased description mod
el of data query is put forward. By depicting informationproviding web service
s as data views with limited access pattern,the model enables them to answer da
ta queries as ordinary resource description framework (RDF) data sources do. The
matching algorithm of corresponding querydata sources is presented. Based on
the dynamic invocation technology of web services,a data integration system is
designed which combines such two kinds of data sources. And a prototype is imple
mented successfully through which the feasibility is validated. 

Key words: data integration, web services, semantic web, resource description framework
