摘要 大量研究成果已经表明,事件在很多文本中是客观存在的。从语义的角度理解,诸多文本是由事件组成的,事件是文本表示的最小语义单位。给出了基于事件的文本表示模型,在此模型的基础上,从文本类型相似度计算和文本内容相似度计算两个层面论述了文本相似度计算的方法。 A large amount of research results have shown that the events exist in many texts. From the angle of semantics,texts are composed of events ,and events are the basic semantic units for text representation. This paper presents the event-based text representation model ,and then discusses the method of text similarity computing from the two sides of text type similarity and text content similarity.
