摘　　要：对等网络已经成为用户共享服务的平台,如何结合用户评价进行服务选择已经成为其中的难点和关键问题。文中针对在开发、动态的网络环境中对服务评价可信度的问题,本文提出了一种基于评价的信任度更新算法,并给出了相关策略。在服务选择的过程中同时考虑服务的信任度和社交度,从而提高查找的准确率,并结合搜索行为聚类算法,降低群体欺骗的可能性。P2P network has becomea platform for services and resources sharing, how to select the resource within user evaluation has become a critical hot issue in an open dynamic environment.Aiming at the problem of resource evaluation trust degree, this paper proposes a new method for evaluation updating algorithm.In the process of resource selecting, this method improve the success rate of resource discovery within resource＇s trust degree.By the clustering algorithm of discovery behavior, this method reduce the likelihood of mass deception.
