A Hybrid Approach for Web Service Selection
Web service selection which is specified to evaluate and select the best candidate from discovered Web services became one of the most significant topics in recent research on Service Oriented Architecture (SOA). In this paper, the authors propose a hybrid approach to solve Web service selection problem. First, they apply Analytical Hierarchy Process (AHP) to evaluate the weights of criteria instead of collect the weights directly from service consumer. In the next tread, they use VIKOR (VIa?ekriterijumsko KOmpromisno Rangiranje) to identify and rank the appropriate candidate services. Finally, in order to demonstrate the proposed method they have afforded an example using four criteria of QoS and five alternative services.
