Web-based Data Mining Intelligent Filtration Technology

This paper is supported by the National High Technology Research and Development Program of China (863 Program) under contract No. 2001AA142100 and the Research Fund of National Education Ministry under contract No. 20010699018 and servers as a predictive researching work tor Network Cooperative Security Technolege Research (863 Program).With rapid development of globable infomationizatione trend, network security, which is closely related to the security of the country, economic and social, becomes a matter of great importance in imformation era. Intelligent information filtering system, which is based on web data mining, is an indispensable part of hack monitoring system. Through research on intelligent information filtering system, the hack monitoring system will get supplemented and become a whole network monitoring system to achive great security.In the first part, data mining, especially web data mining is discussed, detailed in its application in information filtering. Applicatoin of mobile agent in network information filtering and information filtering model in network intrusion detection are analyzed. In the second part, design of web information filtering database is probed into and web computation and web information filtering are analyzed. In the end, design and realization of intelligent information filtering engine is fulfilled with related technology provided.Though deep research is done on intelligent information engine, yet much more work is to be done to achive more breakthroughs in this field.
