摘要：Recently, more and more enterprises are embracing SOA paradigm to integrate and implement interoperable, robust and platform-independent distributed applications. Therefore, service discovery and composition become two main tasks which have gained great momentum. In order to improve the efficiency of service discovery and composition, a method is proposed in this paper. Firstly, some concepts and operations are defined. Then a composition algorithm is introduced in detail after definition. In addition, a QoS-aware evaluation method based on maximizing deviation calculation is proposed to resolve the problem of service selection. An instance and some simulation experiments are illustrated at last. The result shows it is an efficient and effective method for service discovery and composition.
