World-altering Semantic Web Services Discovery and Composition Techniques - A Survey

摘要

Semantic Web services evolved from traditional computational services by semantic descriptions. Recently, there have been many research efforts in the field of semantic Web services, which reveals enormous potential for Service-Oriented Architecture to be promoted to an improved architecture. However, world-altering services have been largely disregarded because of the limited facilities in current description languages to express required conditions. Enterprise Application Integration systems need world-altering services because most of the business services need preconditions to be held prior to their service execution. Moreover, they generate effects, both of which must be contemplated in the service environment. To exploit the semantic Web services in reality, efficient discovery and composition approaches need to be developed to complement the service environment requirements. This paper intends to overview selective methods for discovery and composition of world-altering semantic Web services.
