摘要
随着网络发布的Web服务数量急剧增加,面对数量庞大的服务群,如何从海量的Web服务中快速、准确、高效发现满足用户需求的服务已成为亟待解决的问题。针对传统的服务发现准确性不高,发现方法效率低下的现状,本文提出了一个基于服务交互图的操作组群发现的方法。利用聚类技术,从服务行为相似的层面对服务进行聚类预处理,从而大大缩小服务检索范围,提高服务匹配的时间。并在服务匹配过程中,基于服务交互图的操作组群挖掘,从而可以提高查找的精确度。最后,利用仿真实验对所提出的方法进行验证.
Now,with the increasing of Web services,how to quickly,accurately and efficiently find services which satisfy the user requirements from a large mount of Web services has become a big challenge.For the fact that the accuracy is not high and low efficiency of the way,this article introduced the service of the operation of the group discovered.Firstly,from a similar level of services,the utilization of service clustering potentially enables service match-maker to significantly reduce the overhead,deploy the discovery of candidate services quickly.Secondly,in the services matching process,based on the service of the group of operations,we can increase accuracy.Finally,some simulation results are demonstrated to show the effectiveness of the proposed method.
