随着互联网上发布的服务呈指数级增长，Web服务发现将变得越来越重要。为了发现服务，Web服务的非功能性（QoS）属性，如时间，成本，可靠性，起着重要的作用。虽然有很多研究工作的服务质量为基础的匹配，很少的工作考虑客户的利益作为一个非功能属性。事实上，这是一个重要因素。在本文中，我们，首先，提出了一种新的QoS模型，通过增加一个兴趣度属性。分析了兴趣度的计算方法。在此基础上，构造了一个基于QoS模型的匹配算法。最后进行了仿真实验。实验结果表明，在QoS模型中加入客户兴趣是有效的。
Web service discovery will become more and more important as the services published in Internet expand exponentially. To find a service, non-functional (QoS) properties of Web services, such as time, cost, reliability, play a significant role. Though there are many researches work on QoS based service matchmaking, few works consider client interests as a non-functional properties. In fact, it is an important factor. In this paper, we, firstly, propose a novel QoS model by adding an interest degree property. The computation of the interest degree is analyzed, too. Then, a matchmaking algorithm based on the proposed QoS model is constructed. Finally, a simulation experiments is done. It is shown from the experiments that adding client interests to QoS model is useful and benefic.
