在哪里可以找到NLTK中ClassifierBasedPOSTagger的POS标记的所有标记定义? [英] Where can I find all the tag definitions of POS tagging for ClassifierBasedPOSTagger in NLTK?

问题描述

我使用以下代码来训练ClassifierBasedPOSTagger进行POS标记:

I used the following code to train a ClassifierBasedPOSTagger for POS tagging:

from nltk.classify import MaxentClassifier
from nltk.tag.sequential import ClassifierBasedPOSTagger

me_tagger = ClassifierBasedPOSTagger(train=train_sents, classifier_builder=lambda train_feats: MaxentClassifier.train(train_feats, max_iter=15))
print(me_tagger.tag('My new watch is awesome...'.split()))

其中会打印出以下标签:

Which prints out the following tags:

[('My', 'PP$'), ('new', 'JJ'), ('watch', 'NN'), ('is', 'BEZ'), ('awesome...', 'AT')]

在哪里可以找到该分类器的标记标签定义?我熟悉这些令牌，但是我无法解释BEZ和AT.

Where can I find the token tag definitions for this classifier? I am familiar with these tokens though, but I am unable to construe BEZ and AT.

推荐答案

您可以检查-布朗语料库标记集.
