| 摘 要： | 针对Web服务环境的开放性、欺骗性和不确定性等特征,提出一种基于模糊理论的Web服务信任评估模型——WSTrustM。该模型采用模糊理论的方法对信任度进行度量并对信任评估因素进行组合权重分配,利用模糊集合理论的隶属度概念对实体之间的信任关系进行等级划分。仿真实验结果证明,该模型在Web服务信任评估方面更加准确,可以降低交互风险、保证交互的成功率。

| Abstract: | Aiming at these features of Web service environment such as open,deceptive and uncertain,a Web service trust evaluation model——WSTrustM based on the fuzzy theory is proposed.The model uses the fuzzy theory method to measure trust and combination of weight distribution of trust evaluation of factors,and uses membership degree of fuzzy sets theory to divide grade of entities trust relation.Simulation experimental result shows that the model on the evaluation of Web service trust is more accurate and more reliable,reduces the interaction risk and ensures the success rate of interaction. |
