Using Assumptions in Service Composition Context

Service composition aims to provide an efficient and accurate model of a service, based on which the global service oriented architecture (SOA) can be realized, allowing value added services to be generated on the fly. Unlike a traditional software module, which runs within a predictable domain, Web Services are autonomous software agents running in a heterogeneous execution environment. Because of distributed responsibilities, ownership and control, it is often not feasible to acquire all information needed for the service composition. Thus, there is no guarantee that the service execution has the anticipated effects. Full automation of this process poses challenges to reliable service composition by raising questions such as how to deal with incomplete knowledge during the dynamic service composition, and how to ensure consistent service execution result without human intervention.
