| 摘 要： | 本文通过基于词频统计的内容分析法,将从文本中抽取的高频词与关键词进行匹配对比;根据抽样实验的结果分析了二者的相关度,并以此为基础论证了文献主题自动标引的可行性;结果证明当高频词取到第3位时便能与人工标引的关键词达到一半以上的匹配,在取到7位时便能在85%的程度上替代人工标引.

| Abstract: | This paper compares keyword with high-frequency that be collected from the text through the content analytic approach based on the frequency of the word.The paper has analysed relativity of the two based on the result of the experiment,and discussed the feasibility of the automatic index of the theme of documents.It has be proved that the match degree can be up to over half of the match with the keyword of the artificial index when the high-frequency word chooses to the third,and the artificial index can be... |
