摘要
在Web服务协作环境中选择可信赖的Web服务是分布式软件需要解决的一个关键问题,为此,提出了一种基于协作频度聚类的Web服务信任评估方法.该方法借鉴社会学信任模型,通过Web服务节点间的协作频度对Web服务进行聚类,提出个体信任度、群体信任度和综合信任度的概念,给出了一个Web服务信任度评估模型.还设计了一种基于全局信任管理和本地信任管理的Web服务信任度评估框架.通过构建Web服务库,对评估模型进行了模拟实验,证明了所提出的Web服务信任评估方法的可行性和有效性.
Choosing reliable Web Services is a key issue for distributed software in the Web Services collaborative environment.In order to handle this problem,this paper proposes a Web Service trust evaluation approach based on collaborative frequency clustering.The approach is based on the method of sociological trust model and clusters Web Services according to the collaborative frequency among the Web Service nodes.The concepts of single trust degree,group trust degree and comprehensive trust degree are proposed and a trust evaluation model for Web Service is given.An evaluation framework of Web Service trust based on global and local trust management is designed.By building Web Services depository,the evaluation model is used to simulate the Web Services.Experimental results show the Web Service evaluation method is feasible and valid.
