Abstract
With the development of information extraction technology in the field of natural language ,more and more scholars pay attention to the research of event recognition and extraction ,in which the trigger word recognition and extrac‐tion plays a decisive role .In view that in the present Chinese trigger word extraction results F value is not ideal ,this paper chooses Chinese event corpus ,CEC corpus ,as the training corpus and test corpus and proposes trigger word extraction method based on trigger word extended table combining with machine learning .The experiment result shows that extracting effect is more ideal by using this method ,in which the F value can reach 69 .7% .关键词
