Research On Semantic Condition Expression For OWL-S Service Search And Processing Mechanism

Semantic Web service is the product combining semantic Web withWeb service, by giving the Web service semantic information to realizeautomatic discovery, invocation and combination of services. Thesemantic Web service search is an important content in the field of thesemantic Web service research, it plays a vital role in the life cycle of thesemantic Web service. Semantic expression method of Web searchcriteria as an important research content in semantic Web servicesearch, it has an the vital significance to research. Under the frameworkof OWL-S description language, this paper studies semantic expressionterms oriented OWL-S service search and its processing mechanism.Meanwhile it develops the corresponding software system which helpsusers to describe the semantic Web search terms of service moreaccurately.In this paper, the primary content involves:First, by researching original Semantic Web Service search conditionexpression, and on this basis, combining the feature of OWL-Sdescription model, this paper puts forward the Semantic Web Servicesearch condition expression for OWL-S (SCE-OWL)，gives it’s grammarspecification and operational semantic, illustrates the use of theexpression with examples.Second, it researches the processing mechanism of the Semantic WebService condition expression for OWL-S, illustrates the principle andprocess of the handling mechanism works, puts forward the method ofexpression validity check and the processing method of semanticcondition expression based on the Jena reasoning machine, and gives thealgorithm of processing semantic condition expression.Third, according to processing mechanism of semantic conditionexpression under the framework of OWL-S, it designs and implementsthe semantic Web service processing software, which includes somefunction modules such as the constructing and editing of semantic condition expression、the correctness of the semantic conditionexpression、the reasoning and transform of the expression、the generationof Web services resource search operation and so on.
