Abstract: This paper proposes a QoS-aware model for Web service selection called WSSM-Q. A set of QoS categorization tModels is defined in the model to describe the QoS attributes of a Web sevice. QoS advertisements of service providers are represented by QoS quantification values. QoS requirements of service consumers are represented by constraint and preference values. Web services to meet the requirements of consumers are selected by four phases algorithm. Experimental results indicate the feasibility and efficiency of this model.

Key words: Web service, QoS, service description, service selection

摘要： 提出一种新的支持服务质量(QoS)的Web服务选择模型(WSSM-Q)。该模型定义了一组描述Web服务QoS指标的分类tModel，用QoS量化值描述服务提供者的QoS通告，用约束型需求和偏好型需求描述服务消费者的QoS需求，采用四阶段选择算法选择满足消费者需求的Web服务。实验结果表明该模型是可行的和有效的。
