救急~如何从 wordlist中选取关键词

我是刚接触语料库的小菜鸟,求各位大神指点:
如何从wordlist中选取需要的关键词进行具体的研究呢?听说是和所研究的主题(如:钓鱼岛)相关的一些特殊词汇,但是完全不明白啊~~~
求指点~~~~小女子先行拜谢了~
 
Keywords are obtained by comparing a word list from your text files and a more general reference word list.
 
Probably not. You'll need a more general reference list from large corpora. For example, the word "the" in your corpus would be significantly more frequent than its occurrences in the Academic Word List, but it won't be very interesting...
