推荐答案

Spacy的 POS标记比NLTK更好.更快更好.这是您想做的事的一个例子

Spacy's POS tagging would be a better than NLTK. It's faster and better. Here is an example of what you want to do

import spacy
nlp = spacy.load('en')
doc = nlp(u'Mark and John are sincere employees at Google.')
noun_adj_pairs = []
for i,token in enumerate(doc):
    if token.pos_ not in ('NOUN','PROPN'):
        continue
    for j in range(i+1,len(doc)):
        if doc[j].pos_ == 'ADJ':
            noun_adj_pairs.append((token,doc[j]))
            break
noun_adj_pairs

输出

[(Mark, sincere), (John, sincere)]
