摘要
在语义Web服务中,OWL-S虽然包括一些如质量保证等的有关服务质量参数的描述,但仍缺少一个较为完善的Web服务QoS模型描述,此外,语义Web服务质量的研究主要考虑服务质量的静态因素,而服务的QoS信息动态变化的情况较多,本文实现了对服务质量QoS的语义描述扩展,并在对语义Web服务QoS描述模型研究的基础上,充分考虑服务的QoS信息,提出了基于QoS约束的语义Web服务匹配算法。
In the Semantic Web services,though some description of service quality parameters are included in OWL-S,such as quality assurance etc,but a better description of Web service QoS model is still lacking.On the other hand,the static factor of services quality is considered in researching on semantic Web service quality,but the dynamic changes of service QoS information is more.The semantic description of the quality of service QoS extensions has been realized in this paper,and also the semantic Web service matching algorithm based on QoS constraints has been proposed,which was base on the study of the semantic Web service QoS description model and has fully considered the service QoS information.
