Research on anti-interference algorithm for web service trust evaluation

To realize commercial application of web services, its trust and reputation model has been raised into the agenda. And also many researches have been done on web services trust evaluation model. However, in practice there exist a few interferences to influence web service trust evaluation. For example, service providers may improve his own QoS level on purpose or giving vicious evaluation for his competitors. Service providers also may provide fake services or colludes with each other to gain his high profit. Now there are few good methods to deal with it. We put forward two anti-interference algorithms to eliminate vicious evaluation and collusion. The simulation indicates that the algorithms work well on anti-interference for web service trust evaluation.
