将fried改为fri而不是fry?

我记不起英语中以ied过去时结尾的任何单词，而这些名词的名词形式都以i结尾.

I can't recall any words ending with ied past tense in English that have a nominative form ending with i.

这是一个错误吗?

推荐答案

Porter Stemmer返回的词干不一定是动词的基本形式，也不一定是有效词.如果您正在寻找它，那么您需要寻找一个lemmatizer.

A stem as returned by Porter Stemmer is not necessarily the base form of a verb, or a valid word at all. If you're looking for that, you need to look for a lemmatizer instead.
