Nowadays, with the intemet emergent events taking place frequently, the interaction between intemet public opin- ion and emergent events increases the difficulty of public opinion analysis and pre- warning, and the current public opinion pre- warning system can＇t meet the need. This paper introduced web mining technology into intemet public opinion pre- wanting for e- mergent events, and constructed the public opinion pre- warning system model based on web mining. The mode] included opinion eoUeeting layer, opinion mining layer, opinion analyzing layer, judging and pre - warning layer, integrating all the important func- tions of intemet public opinion pre- warning system for emergent events, and realizing the automation, intelligentization and real- time for the onlleetion, analysis, processing and crisis pre- warning of intemet public opinion on emergent events.
