问:Python 使用 NLTK 的拼写检查器

Q : Python Spell Checker using NLTK

所以我有这行代码使用 NLTK 库

def autospell(text):
        spells = [spell(w) for w in (nltk.word_tokenize(text))]
        return " ".join(spells) 
train_data['Phrase'][:200].apply(autospell) 

我收到此错误消息,告诉我名称拼写未定义,我不知道那是什么意思,因为我认为它来自 NLTK 库,还是我遗漏了什么地方?

查看 Spell Checker for Python,您可能应该使用 autocorrect 库。 示例代码:

from autocorrect import Speller

spell = Speller(lang='en')

def autospell(text):
        spells = [spell(w) for w in (nltk.word_tokenize(text))]
        return " ".join(spells) 
train_data['Phrase'][:200].apply(autospell)
