使用nltk pos标记器标记单个单词会标记每个字母而不是单词 [英] Tagging a single word with the nltk pos tagger tags each letter instead of the word

问题描述

我正在尝试使用nltk pos标记器标记一个单词:

I'm try to tag a single word with the nltk pos tagger:

word = "going"
pos = nltk.pos_tag(word)
print pos

但是输出是这样的:

[('g', 'NN'), ('o', 'VBD'), ('i', 'PRP'), ('n', 'VBP'), ('g', 'JJ')]

它标记每个字母，而不只是一个单词.

It's tagging each letter rather than just the one word.

我该怎么做才能标记单词?

What can I do to make it tag the word?

推荐答案

nltk.tag.pos_tag accepts a list of tokens, separate and tags its elements. Therefore you need to put your words in an iterable like list:

>>> nltk.tag.pos_tag(['going'])
[('going', 'VBG')]
