如何建立一个单词表

所以现在我想制作爱沙尼亚语单词列表〜大约20m的小写唯一单词。要获取wordlist的输入,可以使用corpus of Estonian。语料库文件采用文本编码计划(TEI)格式。我尝试使用正则表达式来查找单词。

这就是我所做的:效率低下,mcv搞砸了,如果单词的hashset不能适应内存,它就会发生制动,它不知道输入编码 - 所以很可能像š这样的字母会产生问题,它不显示估计完成时间,一些控件有默认名称,有些没有,它不使用多任务(不确定是否应该),它使用一些奇怪的修复和许多锁定接口,使它看起来不会“冻结”。至少它很短,你几乎没有注意到没有评论。

好处是,它几乎可以读取没有很多错误的单词,来自.tei,.txt,.csv,smgl,xhtml或任何类似格式的输入。

现在你知道我想做什么,我是怎么做的(有什么问题),而我只想找到怎么做(用最少的手工劳动)。
