Web 2.0 helped bring about the development of social communities, Web services and a host of applications. Web service compositions traditionally utilize the functional and quality-of-service parameters of candidate services to decide which services to include in the composition. However, users of services often form an opinion of a service. User-driven composition techniques will form compositions that likely behave as stated in practice, and which are better received by the users. This paper develops a preliminary framework for integrating social trust in Web service compositions and experimentally validates the utility of the trust framework.
