Research On Internet Oriented Information Filter Technology

WWW has became the biggest net with the richest infonnation.People share the information it provides and feel convenient,but at the same time,people are puzzled by the "information hungry" and "information rubbish" it brings .How to help people to obtain information they really want has became the urgent problem in the net arear.Nowadays,99% web site organize their information to web paper by HTML which is a semi structure format,and provides no semantic,and data organized by it can not be understand by computer,so computer can not analyze those data-in order to help people to find the information they want,some filter systems based on keywords appears.And those systems have became a indispensable part of the filter techniche.On the base of researching those systems,we provide a arithmetic based on QA.AS the Semantic Web put fonvard,it becomes possible that the net can be presented with semantic,and the semantic web provides a way to search information on semantic level. We bring forward a semantic filter model based on Semantic Web-SEMFIT.Taking the innovation design system as application background,we describe two application scene hi the system with QA-based arithmetic and Semantic Web based filter model respectively.
