Research On Model For Personalized Information Retrieval Based On Multi-Agent Of Digital Library

With the population of Internet,more and more users search information with digital Library in recent years。It gets more and more difficult for users to find the information they need fast and accurately, though the digital Library are already well developed。At present,Developed countries in research and development on aspect and attained amazing achievement,however research on the aspect in our country is on the beginning stage。The article will intelligent agent and Multi-Agent technology, agent-oriented software engineering methodology design principle, multi-agent communication and collaboration between the mechanism and application of technologies such as digital libraries。The article consists of four parts。(1)Part one, Based on the design of the structure of the Multi-Agent system。Description of the Agent,and the basic structure of the Multi-Agent model structure level,described Agent fuctions of the various components and services strategy in detail the structure of the Multi-Agent levels。(2)Part two, construction an personalized system model of information searching,and takes the software structure for example to prove the feasibility of this model。At last, An Multi-Agent based personalized active information services for digital library was proposed and from the model of the work processes and key fuctions of the two modules in the model was discussed。(3)Part three,from the model of the work processes and key functions of two modules in the model were discussed。The research on cooperation and negotiation mechanism of Multi-Agent model in this article。Through the cooperation and negotiation mechanism of Multi-Agent on,the more efficient model to achieve the objective of services for users。(4)Part Four, Through the application of the current domestic Multi-Agent technology precedent for the application of case-studies unit, said a digital library of personalized information services Multi-Agent technology to be further improved in。Through smart Agent technology will be applied to digital library information retrieval system, combined with the characteristics and advantages of Agent, proposed a Multi-Agent-based personalized information retrieval model, Main goal of this article is that applying intelligent Agent to digital library information service system in order to raise its personality service level, Implementation user-oriented interest in the information search。...
