Embodiment Construction

[0076] The above content has fully disclosed the present invention, and the implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0077] In the example of the present invention, by subdividing and coloring the types of input and output places, the functional information (IOPE) of semantic Web services described by OWL-S is mapped to the expanded Petri model, as shown in the attached figure 1 shown.

[0078] The behavior of the execution process of the Semantic Web service (sub-service), corresponding to the transition in the Petri net, is represented by T s express. The sub-service is mapped to the extended Petri net model, represented by WS_P, as in formula (6)

[0079] WS_P=(IP,OP,P pre ,P effect , T s ) (6)

[0080] When the sub-service does not contain PE information, P pre =Ф and P effect =Ф, the sub-servi...

Abstract

The invention discloses a method for combining semantic Web services based on an expanded Petri network model. The method is characterized by including the following steps that (1), according to sub-services involved in the combining process of the semantic Web services, an original Petri network model is expanded, and the expanded Petri network model of the sub-services is formed; (2), through the expanded Petri network model of the sub-services, a formal description and a function mechanism of the expanded Petri network model of a semantic Web service combination result are achieved combined with formalization presentation of the semantic Web service combination result; (3), on the basis of the expanded Petri network model obtained according to the step 1 and the step 2, the semantic Web service combination is achieved. A Petri network is used as a basic model for expansion, moreover,the service combination method based on the expanded Petri network model is provided, and therefore dynamic combination of execution sequences of the sub-services is achieved.

Description

technical field [0001] The invention belongs to the technical field of semantic Web service composition. Aiming at the semantic Web service composition model and method, and processing the service request immediately initiated by the user, a semantic Web service composition method based on the extended Petri net model is proposed and realized, especially how to Process and represent the dynamic process of service composition and the complex relationship between sub-services. Background technique [0002] Semantic Web services combine Semantic Web and Web services, and use the rich semantic description and logical reasoning capabilities of Semantic Web, so that machines can "intelligently" understand Web services and user requests, and realize automatic discovery, combination, monitoring and invocation of services . However, due to the limited function of a single Semantic Web service, the existing single service cannot meet user requests. How to intelligently analyze user r...
