Automatic Web Service Semantics Tagging Method

This paper analyses the similarity between XML schema and DAML and develops a kind of common middle data model which can bridge both of them so that they can be matched by the way of mapping XML schema and DAML to the common data model.By doing so,this method can facilitate adding semantics to Web service automatically,which has been proved by experiments.The result shows that the method is worth being further studied and has a wide application foreground because it is necessary for adding semantics and efficiently to Web service precisely to store a mass of ontologies during the research work of Web service composition based on ontologies.
