摘要
分析了现有Web服务发现的不足,在系统研究Web服务发现框架的基础上,将QoS模块引入,提出一个支持QoS约束的语义Web服务发现模型SWSDM-QoS。在该模型中,支持QoS的服务发布、查找和反馈,并在此基础上提出一个基于QoS约束的服务选择算法。已经基于Microsoft.NET平台实现了一个原型系统。
There is lack of clear description of QoS in the current web service described by OWL-S, which make it hard to get the optimal service. The QoS module to the web service discovery architecture is introduced, and a web service discovery architecture SWSDM- QoS that support QoS constraint is advanced. This model supports web service publish with QoS information, web service search with QoS-constrainted and feedback with QoS. And a web service selection algorithm based on QoS constraint is also provided. A prototype based on Microsoft. NET is implemented.
