QoS-Aware Service Selection under Consumer´s Reputation

Analogous to the best buy information in physical merchandise, community-based reputation reflected QoS regarding specific service via feedback about customerspsila satisfaction degree. However, dishonest consumers are not responsible for their feedback information due to commercial benefits. In this paper,a trusted service selection model based on consumer reputation derived by community feedback information is proposed. It can effectively analyze the attribute weighting with fuzzy entropy method and rationally prioritizes the ranking order of service alternatives. Moreover, a satisfaction-based index of service consumer is established to perform the discrimination of fuzzy ranking of service alternatives. Finally, an example of QoS-aware web services selection is illustrated to demonstrate the proposed approach. Experimental results also demonstrate that the consistent ranking can easily be obtained by employing the proposed approach.
