中文摘要：
在开放的Web服务环境中，由于无法保证用户使用服务后给出的反馈等级是真实可靠的，导致服务的信誉度评估结果与实际值存在较大偏差，进而服务选择失败率较高．为了克服上述问题，提出了一种用于wleb服务选择的信誉度评估方法．该方法的主要思想是，通过反馈核查、校正和检测这3个信誉度评估模块对服务的信誉度进行评估．仿真结果表明，所提出的方法不仅有效提高了信誉度评估的客观性，还显著减小了服务选择的偏离度．
英文摘要：
In an open Web service environment, it is difficult to guarantee the authenticity of the feedback ratings reported by users after they have already consumed some services, which leads to large deviation between evaluation results and actual values of service reputation. Therefore, there are much more failures in service selection. To address the above problem, this paper proposes a reputation evaluation approach for Web service selection. The main idea of the proposed approach is evaluating the reputation by three reputation evaluation model including feedback checking, feedback adjustment, and feedback detection. Simulation results demonstrate the proposed approach not only improves the objectivity of reputation evaluation effectively, but also reduces the deviation of service selection significantly.
