Research of Active Information Service System Based on Intelligent Agent

The current active information service system focuses too much on the study of personalized modeling, and there is less research on artificial participation, automatic information analysis and automatic information update. According to the requirement of active information service to topical web, the article integrate agent technology, information filtering technology, crawling technology on Heritrix and the technology of web information extraction on HtmlParser ,based on which a model that describes Active Information Service System based on Intelligent Agent is presented. The model embeds the intelligent agent technology, on one hand, it could accomplish four active functions, they are active information collection, active webpage parsing, active information filtering, active information publishing, on the other hand, it has intelligence to a certain degree and has some learning abilities in parsing module. The characteristic of the model is its flexibility and adaptive capability.
