摘要： 由于传统的基于关键字和简单分类的Web服务发现机制较少考虑服务质量(QoS)，因此不能很好地满足用户的需求。针对该问题，提出一种基于QoS的Web服务发现模型，通过引入QoS代理机制以支持基于QoS的Web服务发布与发现。在此基础上，根据不同用户的QoS需求，提出一种基于QoS的Web服务发现算法。实验结果表明，该算法具有较高的准确率。

Abstract: The traditional Web service discovery mechanism that is based on keywords and simple classification can not satisfy users’ requirements due to the lack of Quality of Service(QoS). Aiming at this problem, a QoS-based Web service discovery model is proposed, in order to support QoS-based Web services publish and discovery, the QoS broker mechanism is introduced into the traditional Web service discovery model. On the basis of these, according to the characteristics of QoS requirements of different users, a QoS-based Web service discovery algorithm is proposed. Experimental results show that the algorithm has higher accuracy.

Key words: Web service, service discovery, Quality of Service(QoS)
