基于事件的文本表示方法研究

Research on Event-based Method for Text Representation

在传统文本表示模型的研究基础上,针对叙事类文本,考虑以事件作为基本语义单元,并结合图结构表示的特点,提出了一种基于事件的文本表示方法——事件网络。该方法利用事件和事件间的关系来表示文本,能够较大程度地保留文本的结构信息及语义信息。实验结果表明,基于该方法的自动摘要取得了较好的效果。

By 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.
