【Abstract】 This paper aims at determining the relevance between text paragraphs by making use of Vector Space Model,and thereof realizing automatic analysis of text structure.We can find each sub theme which constitutes the theme of total text,and then realize automatic abstraction by taking such sub theme as the point of departure.In this sense,this paper will propose a new way to the study of automatic abstraction techniques.On the other hand,we can determine the various types of text structure,this paper provides some useful information for the other information processing techniques,including the technique of document retrieval.更多还原
