摘　　要：为了解决Web服务中的节点评价存在节点的计算性能和网络连接等方面的物理差异、节点评价标准的主观兴趣差异及信任评价考虑因素的全面性差异的问题,提出了一种基于声明机制的信任评价模型。该模型通过建立声明机制的方法,考虑了节点物理差异和主观差异,对信任评价标准进行了细化。仿真实验分析表明,新模型精化了信任算法的粒度,提高了信任评价的准确度,体现了节点的个性化特性,具有很好的可扩展性。The paper proposes a new trust model based on declaration mechanism to solve the evaluation differentia problems in peers, trust evaluation in Web service, including the aspects of the physical differentia of peers＇ capabilities in connection and computation, the subjective differentia of peers＇ preferences in trust evaluation, and the comprehensiveness differentia on trust evaluation factors. The trust model takes the physical differentia and subjective differentia among peers into consideration, and sets the evaluation criterion of trust in detail. The experimental results show that the proposed trust model can thin the granularity of the trust evaluation criterion and improve the accuracy of trust evaluation. Further-more, the model also embodies the personal characteristic of peers and better scalability.
