摘要
现有Web服务的可信评估机制大多忽视Web服务使用者及应用场景的差异性,其评估结果的准确性无法得到保证。提出了一种基于可信证据的Web服务可信评估机制,实现了可信证据的Web服务调用主动探测、服务容器自动反馈和用户反馈收集,同时提出了一种基于用户反馈的上下文敏感可信评估方法,全面考虑了Web服务质量属性的上下文相关性,进一步提高了Web服务可信评估的准确性。
The differences of users and use environments are mostly ignored in current trustworthiness evaluation of Web services, leading to few guarantees for the evaluation accuracy. This paper proposes a trustworthiness evalua- tion mechanism based on trustworthiness evidence. As for evidence collection, it introduces three mechanisms： invoking based on Web service, automatic feedback through container monitoring and collecting user feedbacks. In addition, it proposes a novel context-sensitive mechanism to evaluate trustworthiness based on user feedbacks, takes account of context related to the quality of service and further obviously improves the evaluation accuracy.
