英语文档之关键词统计

英语文档之关键词统计

1、操作目的

在阅读英语文档之前，一般需要有一定的英文基础。但是，在很多时候，我们不能知道自己的单词储备是否可以有效地完成阅读。这时，我们需要补充单词。自然而然地可以想到，我们应该补充高频单词用于提高阅读体验。高频，使用直接的统计方法就可以得到高频单词的分布，进而提升阅读体验。

2、操作方法

首先要找到软件，在百度上查了一下，replace pioneer可以实现该功能。其中的pattern counter支持在txt文件中查找单词并给出统计。当然，如果有实力的话也可以自己编程。在实际使用过程中查找一个几十M的文件需要几分钟。

自定义输入的正则表达式：[a-zA-Z]{4,14}

3、操作结果

以ug585为对象操作得到以下结论，取前面的数据：

Number    4_word([a-zA-Z]{4,14})

这里是出现次数超过一百次的单词。有时间就可以多记，没时间少记。这里面大部分单词是基础单词，一扫而过就行。感觉记住超过1000的即可基本阅读。
