A Web Service Composition Modeling and Evaluation Method Used Petri Net.

The emergence of Web services opens a new way of Web application design and development. It has led to more interest into Web service composition, which is an active area of research. The formidable problem of efficient and effective composition of existing Web services is the subject of much current attention. The study of modeling is one of the most important parts and a key layer of Web service composition. Therefore, there is a need for modeling techniques and tools for reliable Web services composition. In this paper, we propose a method used an Advanced Object-Oriented Petri Net (AOOPN) to model and evaluation the process of Web services composition. This method is expressive enough to capture the semantics of complex Web services combinations. [ABSTRACT FROM AUTHOR]
