一种基于多Agent的Web服务有效发现方法

An Efficient Approach to Web Services Discovery with Multi Agent

在系统地讨论Web服务与Agent概念的基础上,提出了将一个Agent描述成一个Web服务,并通过UDDI发现该服务而将Agent和Web服务集成在一起的实验方案。在该基础上,设计了一个基于多Agent和语义驱动的Web服务有效发现中间件平台,重点对其组件、功能和交互过程进行了全方位描述。最后,通过一个运行实例的Web服务智能发现过程,展示了该方法是可行和有效的。

This paper first introduces the integrating concept of agents and Web services in which an agent is viewed as an abstract notion that must be implemented by a concrete Web service. The above approach allows Agent services invoke Web services and vice versa by accessing UDDI business registry. Then, a multi Agent-based and semantics-driven Web services middleware platform using existing standards instead of proposing other standards is put forward, and its components, functions and interoperations are discussed. Finally, a running example is given. The preliminary experimental results indicate that the platform can help consumers retrieve proper Web services and the platform is quite feasible for solving problems with real world sizes.
