英文摘要	In this paper, the method ofextract event from newspaper is proposed. First, the candidate sentences are select by using trigger word. Then, statistic models in three levels are consisted of extract model, which is sentences level, news level and topic level is used to extract event from candidate sentences and the probability of extracted events is calculated by three levels model.
