【摘要】 本文描述了一个基于修辞结构理论的文摘系统的实现方法,首先介绍了修辞结构理论的一些概念和思想,然后描述了该理论在自动文摘的实现方法。修辞结构理论的分析是把文摘候选句和它们之间的修辞关系保留下来,提取出文摘句。最后用基于模板的自然语言生成方法,连同候选句之间的修辞关系生成一个准确、流利的文摘。更多还原

【Abstract】 In this paper, we present an automatic text summarization method based on natural language understanding by using RST (Rhetorical Structure Theory). The first part gives a general introduction to the Rhetorical Structure Theory. RST is an analytic framework designed to account for text structure at the clause level. The system extracts the rhetorical structure of text and the compound of the rhetorical relations between sentences, and then cuts out less important parts from the extracted structure. Finally it uses the natural language generation method based on model to produce an exact and fluent abstract.更多还原
