Abstract: B3y studying some traditional text representation models, this paper considered the event as a basic semantic unit for narrative texts, and presented a new event based text representation method (Event Network) , which combines the characteristics of the graph structure. This method uses events and the relationship between events to represent the text, and can retain the structure information and semantic information of the text to a greater extent. The experimental results show that automatic summary based on the method has better performance.
