Compatibility Verification of Web Service Composition Based on Pi-calculus

With the rapid development of web services, service computing is evolving into an important computing paradigm. One of the challenges in this evolution is how to ensure the correction of service composition. To verify the compatibility of composite service, we use pi-calculus to model the composite service process and present the related concepts and theorem of composition compatibility. Moreover, we propose an automate method to generate the process expression for increasing the verification efficiency.
