Abstract: Aiming at the problem that QoS evaluation is impossible or unreliable when involved criterions are beyond service domain, this paper presents a reliable QoS evaluation model based on Web service community. This model defines the assistant domain Ontology besides the domain Ontology, and makes it possible to correctly evaluate the QoS in different domain by using criterion trees and criterion forest weighted by Analytic Hierarchy Process(AHP). It imports Web service community to manage services on overall control that improves reliability of the evaluation.

Key words: assistant domain Ontology, criterion tree, assistant criterion forest, Analytic Hierarchy Process(AHP), Web service community

摘要： 针对涉及本领域之外QoS评价的不可计算和不可信问题，提出基于Web服务社区的可信QoS评价模型。该模型在本领域外定义辅助领域本体，并在两者中使用层次分析法构造评价树和评价森林，使本领域外的QoS可以被正确评价。引入Web服务社区概念，通过主Web服务进行宏观总体控制，提高评价结果的可信度。
