The description logic concept is used to annotate service IO and the description logic assertion is employed to describe service PE(preconditions, effects). TBox subsumption checking is used to measure the subsumption relationship between IO descriptions of service request and advertising; ABox consistency checking is used for checking the logical implication between PE descriptions of service request and advertising. Based upon the logical implication, four kinds of PE matching degrees are proposed to measure and compare the pros and cons of the results of matchmaking. They are the exact, perfect, side-effect and common match. Experiments show that the method has a higher precision rate under the same recall rate compared with the existing method.展开更多

With this method, semantic service description can be achieved by semantic annotation of the elements in a Web service description language(WSDL) document with concepts of geographic ontology, and then a common under-standing about service semantics between customers and providers of Web services is built. Based on the decomposition and formalization of customer requirements, the discovery, composition and execution of GI Web services are explained in detail, and then a chaining of GI Web services is built and used to achieve the customer's requirement. Finally, an example based on Web ontology language for service (OWL-S) is provided for testing the feasibility of this method.展开更多
