Trustworthy service selection and composition - reducing the entropy of service-oriented Web

Current e-service selection relies upon service registries to make recommendations. It is almost impossible to capture and make use of valuable personal service evaluations, e-service composition on the other hand employs intelligent planning for composition plan generation, which fails to scale in a large open environment such as the Web. In this paper, we consider trust evaluation and propagation as the fundamental driving force for service selection and composition, and proposed a framework that will facilitate the growth and evolution of a service-oriented network into a self-organised trustworthy virtual collaboration environment. Viewing a service-oriented network (Grid or Web) as an ecosystem, this framework is based on personalised service recommendation, social network analysis and emergent intelligence.
