摘要
对Web服务的信誉度、信誉关系属性和信任类型进行了形式化的定义,并据此来评估Web服务的信誉行为,考虑到Web服务信誉度的不确定性,在引入信誉量化概念的基础上,对现有的UDDI规范进行扩展,提出了Web服务信誉度评估模型,并深入研究了Web服务的信誉度评估方法及模型的实现方案,与其它的Web服务信誉度模型相比,该模型通过使用客户反馈、主动监视的机制以及采用第三方权威机构评价Web服务的信誉度,从而保证了信誉度的公平性和有效性。
Considering the unceltainty ofweb service reputation, reputation, reputation relation attributes and reputaton types for evaluating reputation action are defined, and the concept of quantification is introduced, then a reputation evaluation model of web service is put forward by extending actual UDDI criterion, the means of evaluating reputation of web service and the scheme of realizing the model seriously are studied. Comparing to the other reputation models, the model utilized the third-party authoritative institution fully, and used the mechanism of consumer feedbacking and active monitoring for evaluating and adjusting reputation value of web service in the UDDI, therefore, the impartiality and validity of reputation information are ensured.
