摘要
在大量相似服务共存竞争环境下,为了实现面向服务质量的Web服务选择,分析了Web服务质量综合、模糊、动态和可配置特征,指出了当前服务描述和查找标准在服务质量信息描述和应用方面的不足。提出了Web服务的服务质量语义描述模型;设计了基于综合模糊评价系统的柔性可配置Web服务的服务质量需求语义描述模型;提出了改进的服务描述、查找和集成过程,利用基于合同网的交互协议规范的服务提供方、中介服务和服务用户3方协作,实现了面向服务质量的交互式Web服务选择。
Coexistence and competitions exist among a fair amount of services,in order to implement Web service selection oriented to Quality of Service （QoS） ,a QoS semantic description model for Web service was defined after analyzing synthetic, fuzzy,dynamic and configurable characteristics of Web service quality and pointing out shortcomings of current service description and search standard in service quality information description and application. A flexible and configurable QoS requirement semantic description model was designed based on the fuzzy synthetic evaluation system. Subsequently,improved service universal description,discovery and integration process with QoS considerations were proposed. QoS oriented interactive Web service selection was realized through the contract--net --based collaboration of service consumer,service provider and service broker.
