The invention discloses a matching method of semantic WEB service and a system thereof. Based on similarity between request and candidate service, the matching method and the system synthetically consider functional and non-functional factors, and introduce a phasing filtering mechanism.

The invention discloses a semantic Web service verification method based on a dynamic description logic and model detection. Based on a model verification technology in a semantic Web environment, the dynamic description logic is introduced and action actuation of the dynamic description logic is used as a state changing reason in a Web service model, so that a conventional model detecting technology is applied to Web service verification under a semantic Web service verification environment. On the aspect of a system model, the semantic Web service is abstracted as a state transition system in model detection; meanwhile, an action theory is introduced for abstracting preconditions and implementation results of atomic service as atomic action of an action theory and taking the action implementation as a state changing reason in the atomic service. On the basis, a model generated by the action implementation is inspected to whether meet temporal specification or not. The semantic Web service verification method can be used for compensating the defect that the limitation of the state changing reason in the Web service is not considered in the conventional verification method, and the Web service verification method is enriched under the semantic Web environment.
