Research On MultiAgents System Based On XML

With the development of Agent technology,the application Agent-based will be more and more widely used, especially at Internet.Then,two problems will be confronted when we program based on Agent at Internet.One is the communication between Agent knowledge degree,and the other is communication among different Agent systems.To these problems of Agent communication,the paper put forward the Communication Frame of Mutti-Agent based on KQML and XML(MACF-KQML&XML) at Internet,based on domestic and foreign research at present. We use KQML to resolve the problem of communication among Agents and use the method that XML parser pack KQML to resolve the problem of communication among different Agent systems .At the same time,the paper create the framework and program the function Module of communication frame.During Agent is communicating,it calculates and reasons the messages based on its knowledge base firstly,then take appropriate vocabulary set express. Secondly, the KQML module expresses these messages to languages of KQML format.Then,the XML module packs them to XML document,which can be passed among diferent Agent system.The Agent module mainly programs the function of Agent.The KQML module mainly takes charge the function of knowledge degree communication among Agents. And the XML module mainly packs the languages of KQML format, then transmits by XML document. The advantage can make Agent framework program and Agent communication program separated.It can reduce difficulty of Agent-system program and communicate in different platform,too.At last,the paper discusses the application of MACF-KQML&XML and analyses the condition and circumstance. Meanwhile, we program Mutil一Agent system by Java,and program the Agent of which to Applet little program.Then,we embed the Applet in web.Users can login the web and use the system.At the same time, we realize Agents communication by the method of MACF-KQML&XML. It solves the problems among different Agents and among different Agents under different platform.
