Abstract: For the purpose of using the constraintrules between verbs and their arguments in the event extraction, an approach of Chinese event IE based on verb argument structure was proposed around the model variant, which was formed by introducing the verb argument structure into an event model. First pre-treating and syntactic analysis of text were made to get its grammatical structure. hhen the structure was compared with the properties of verb argument structure to find out the disposal argument of each verb. Finally the features of the corresponding events were determined by the semantic properties of argument and the event extraction was completed. Experimental results show that this method can improve the extraction system performance, increase the efficiency of extraction.
