The Research And Implementation For The Trusted Web Service Selection Platform

It has become a major way to satisfy the given request in the SOC environment by service composition building software applications. The choice of service is an important part of the service composition, and the result of the choice has important influence on the credibility of the composite service. The existed methods lacks of synthetically considering service behavior in the process of service selection, thus it reduces the credibility of a composite service. And there aren’t publicly available Web service selection platforms in the business community and academia at present.In view of this, the paper is based on introducing the knowledge related to the Web services and existed services selection method, firstly, oriented a composite service static process, it designs a process structure similarity measure method based on synthetically considering of process structure and the identify semantic. Secondly, oriented the dynamic behavior of the composited service, it designs the service behavior similarity measure method based on defining the behavior edit distance, and then puts forward a highly reliable service selection method, which synthetically considers the static structure and dynamic behavior characteristics of service process model.Further, the paper is based on the trusted Web service selection method, and designs and implements a trusted Web service selection platform using the C#.Net technology in the environment of Visual Studio2010. First of all. the platform realizes the editing function of the Web service model, which is used to establish the Petri net model for demand service and available service. Secondly, the platform has realized the similarity measure of static structure and dynamic behavior of the process model, which is used to implement the trusted Web service selection. Finally, the tourism travel service shows the feasibility of the proposed method and effectiveness of the developed platform.
