NLTK的所有pos标签是什么？
如何find一个包含所有可能的自然语言工具包（nltk）使用的pos标签的列表？
这本书有一个笔记如何find标签集的帮助，例如：
nltk.help.upenn_tagset() 其他人可能是相似的。 （注意：也许你首先必须从下载帮手的Models部分下载tagsets ）
标签集取决于用来训练标注器的语料库。 nltk.pos_tag()的默认标记器使用宾州树库标记集 。
在NLTK 2中，您可以按照以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，但文档指出现成的标记器仍然使用Penn Treebank标记集。
为了节省一些时间，下面是我从一个小语料库中提取的列表。 我不知道它是否完整，但它应该有大部分（如果不是全部）来自upenn_tagset的帮助定义…
