答案 2 :(得分：57)
标签集取决于用于训练标记器的语料库。
nltk.pos_tag()的默认标记使用Penn Treebank Tag Set。
在NLTK 2中，您可以按如下方式检查哪个标记器是默认标记器：
import nltk
nltk.tag._POS_TAGGER
>>> 'taggers/maxent_treebank_pos_tagger/english.pickle'
这意味着它是在Treebank语料库上训练的最大熵标记器。
nltk.tag._POS_TAGGER在NLTK 3中不再存在，但the documentation states表示现成的标记符仍然使用Penn Treebank标记集。

>>> tagdict.keys()
['PRP$', 'VBG', 'VBD', '``', 'VBN', ',', "''", 'VBP', 'WDT', ...

您可以在此处下载列表：ftp://ftp.cis.upenn.edu/pub/treebank/doc/tagguide.ps.gz。它包括令人困惑的词性，大写和其他惯例。此外，wikipedia有一个类似于此的有趣部分。部分：使用词性标签。
答案 7 :(得分：0)
只需逐字记录即可。
import nltk
nltk.download('tagsets')
nltk.help.upenn_tagset()
nltk.tag._POS_TAGGER不起作用。它将给出 AttributeError：模块'nltk.tag'没有属性'_POS_TAGGER'。 NLTK 3中不再提供该功能。
答案 8 :(得分：0)
在python中运行以下代码以获取有关所有pos标签的信息。
import nltk
nltk.help.upenn_tagset()
