摘要: 服务的描述语言，元数据的存储方式以及服务的匹配算法是影响服务发现效率和质量的3个主要问题。该文从这3个问题出发，提出了基于Chord的带有QoS的语义Web服务发现系统。将服务质量(QoS)信息加入到OWL-S中来描述服务，并称之为OWL-QoS；采用基于Chord的分布式方式存储元数据；通过基于OWL-QoS的服务匹配算法来查询服务。实验表明，这种方法有效地提高了服务发现的查询效率与查准率。Abstract: Service description language, metadata storage and service matching algorithm are three critical factors influencing the efficiency and quality of service discovery. This paper presents a prototype system of Chord-based semantic service discovery with QoS(Quality of Service). The information of QoS is put into OWL-S (Web ontology language for services) to describe services, and Chord-based distributed storage is adopted, and OWL-QoS based matching algorithm is used to discovery services. Experiment results show that the approach presented in this paper can improve the efficiency and accuracy of service discovery commendably.
