可信Web服务的选取及优化是基于Web服务的软件系统是否成功的关键因素之一,因此本文针对Web服务的可信性度量问题,提出可信Web服务的偏好本体度量模型,利用一个独立的第三方——可信度量中心TMC来评测Web服务的可信度,采用面向偏好的领域本体刻画度量指标及其权重,借鉴模糊描述逻辑设计了模型算法完成Web服务可信度的推算,并开发了可信Web服务智能推荐系统以验证该方法的可行性和有效性.
The selection and optimization of Trusted Web Services is one of the key factors in the success of Web Services-based software systems. Therefore, in this paper, aiming at the problem of the credibility of Web Services, this paper proposes a preferred ontology measurement model of Trusted Web Services, Third party - Trusted Metric Center (TMC) to evaluate the credibility of Web Services, uses the domain-oriented ontology to delineate the metrics and their weights, draws on fuzzy description logic to design a model algorithm to calculate the credibility of Web Services, and develops Trusted Web Services Intelligent recommendation system to verify the feasibility and effectiveness of this method.
