| 摘 要： | 该文首先介绍了Web Service的相关技术以及基于语义的Web服务发现机制,并在此基础上提出了用欧几里德距离来计算同类服务中服务质量(Qos)与用户要求的服务质量的相似性,从而选择与用户要求最接近的服务,这样可以避免同时多个请求者都选择服务质量最好的那个服务.减少了发生负载问题的几率及解决负载问题的调度次数.

| Abstract: | In this paper,it first introduces the technology of the Web Service and the mechanism of Semantic Web Service selection.After that it provides that we compute the similarity of Qos which is provided by Web Service provider and required by client based on the computation of Euclidean distance.We select the proximate Web Service.From this we can prevent all the client from selecting the Web Service provider which its Qos is the best and reduce probability of load problem and the dispatch frequency.Meanwhile in this paper it brings market rule to Web Service.The Web Service provider can understand the requirement of client and improve the Web Service and the competitive ability so as to satisfying the need of client better. |
