| 摘 要： | 本文针对应急预案自动主题抽取的需求,采用词汇语义相关度计算的方法,构建了一个基于词汇链算法且符合人的主观感受的主题抽取模型.模型根据应急预案文本的特点,运用了自然语言处理技术,改进了原始的词汇链生成算法,提出了一种多因素词语权重算法.通过与人工抽取主题词的实验结果相比较,该主题提取模型在查全率和查准率上都取得了较好的效果.

| Abstract: | The paper aimed at the requirement of the automatic extraction of subject from the emergency plans,took up with the measures of lexical semantic relatedness,and has constructed a subject extraction model based on the lexical chain algorithm which accords with human's subjective feeling.According to the characteristics of the emergence plans text and the needs of the project,the model used a number of natural language processing methods,improved the original chain generating algorithm,and brought forward a w... |
