摘　　要：引入QoS本体,提出了一种基于QoS本体的语义Web服务选择算法.该算法通过构造Web服务的QoS本体模型以支持异构QoS参数的语义描述和度量,并将QoS语义匹配和数值匹配相结合,从而更准确地为用户选择满足其个性化需求的Web服务.仿真实验表明,基于QoS本体的语义Web服务选择算法能够充分利用QoS语义和数值信息,为用户选择更合适的服务,实现用户对Web服务的个性化需求.Because the current web service selection mechanism was lack of the support of semantic quality of service,the QoS ontology is introduced.Therefore,a new semantic web service selection algorithm based on QoS ontology is proposed in the paper.First,the QoS ontology model is constructed to support the semantic description and measurement of heterogeneous QoS parameters.Then,the semantic QoS matching is combined with its numerical matching to select the satisfactory web services for service requesters.The experiment shows that,the semantic web service selection algorithm based on QoS ontology can adequately utilize semantic and numeric QoS information to select more satisfactory web services for users,it satisfies the users＇ personalized requirements.
