| 摘 要： | 针对多个服务提供方提供相似Web服务的状况,在功能属性服务发现研究的基础上,尝试基于QoS的按需服务发现过程研究,其核心是先聚类后排序.首先利用FCM聚类思想将用户QoS需求信息和Web服务资源的QoS信息进行合并聚类,再通过相似度计算确定同一分类内聚类对象的次序,最后以一个算例说明了该过程可以根据用户的QoS需求发现服务.

| Abstract: | According to the functionality-similar web services,a service-on-demand discovery process based on QoS was proposed while functional attribute service was discussed.The core of which was clustering followed by sequencing.The QoS information of Web Service resource was FCM clustered with the user′s QoS requirement information firstly.Then,similarity computation can form a same classification clustering sequence.Lastly,it is illustrated that service-on-demand can be discovered efficiently and effectively by a numerical example. |
