Proxy based framework for personalized Web service composition

Service-oriented computing and Web services are becoming the dominating computing model as internet and cloud computing become pervasive. More and more services with the same functionality are becoming available, and QoS (Quality of Service) is the main factor to differentiate them. The overall QoS of a business process must meet user´s requirement. Our study proposes a proxy-based framework to facilitate the dynamic integration of Web services into business process and fast detection of abnormalities. The major functions of our dynamic proxy-based framework include service collection, composition, selection and adaptation. Our study concerns both functionality and QoS characteristics of Web services to identify the optimal business process solutions.
