摘要
服务质量评估是基于QoS服务选择的前提和基础。然而,目前的Web服务发现方法在服务质量评估过程中没有充分考虑服务质量的动态变化,不能对服务的表现进行准确的预测。在分析现有相关研究的基础上,提出了一种基于服务质量预测的Web服务选择方法,并详细介绍了该服务选择方法的实现和服务质量预测模型的结构。
QoS evaluation plays a key role in QoS- based service selection. However, current QoS- based service selection methods haven＇ t taken the dynamic nature of QoS into consideration and lack mechanisms to provide dynamic service performance prediction effectually. In this paper, propose a Web service selection meehanisrn which is based on QoS prediction. The architecture of QoS-prediction based service selection framework and the QoS prediction model are discussed in this paper in detail.
