Abstract

In composite services, the atomic service reputation is becoming important when many similar functional services could be provided for selecting under the heterogeneous and loose- coupled circumstance . However, existing reputation measurement methods pay little attention on user credibility which has a great influence o n accuracy. In this paper, we define user credibility as the ability of honest users to provide rational feedback s, and propose a novel service reputation management model based on service invocation information and user feedback. This method consists of three parts: malicious feedbacks distinguishing, user credibility evaluating and service reputation predicting. Firstly, a clustering algorithm is conceived to filter out malicious feedbacks. Then a feedback deviation based algorithm is proposed to evaluate the user credibility considering service QoS similarity. Finally, an algorithm on the basis of user credibility and honest feedback s is applied to predict service reputation . Experiment proves that our model can effectively detect malicious feedbacks and precisely measure service reputation with low error.
