Evaluation Mechanism for Web Service Based on Semantics and Reputation

In open network, unfamiliar web services are unavailable due to lack of effective mechanism to evaluation their performances for users. In order to help the user recognizing unknown web services, semantics understanding and reputation based evaluation mechanism is introduced into web service research. Semantics understanding based evaluation is according to the user´s requirements semantics and the semantics of candidate web service´s capacities. Reputation ranking method is proposed to build up a neutral and whole belief about a web service. Web service reputation is composed by two facets: time limitation and ranking delay. Finally, the experiment shows that our approach is feasible and effective.
