Abstract

Current Web service discovery methods are based on centralized approaches where Web services are described with service interface functions but not process-related information. It cannot guarantee compatibility of Web service composition, nor can it makes Web services easy to complete a deadlock-free and bounded process transaction. Furthermore, centralized approaches to service discovery suffer from problems such as high operational and maintenance cost, single point of failure, and scalability. Therefore, we propose a structured peer-to-peer framework for Web service discovery in which Web services are located based on service functionality and process behavior. It guarantees semantic compatibility of Web service composition, and achieves the automated composition at the level of executable processes.
