Semantic Web services component automata based ontology

In view of the semantic questions of the WSDL in describing service component’s discovering, matching, choosing and so on. an automata based on Ontology is proposed to implement the semantic recognition serivce, which can finally meet the request of service component. Firstly Analysis of OWL-S and WSMO based on Ontology is made, then the semantic Web service component antomata is established. Finally, under the support of WSMO this theory is applied in the information system of Aba Prefecture. The practice indicates that the automata effectively resolved the service component flow modelling and decscription in the semantics recognition.
