python - 如何从句子中提取名词形容词对

Question

我想从这个句子中提取名词-形容词对。所以，基本上我想要这样的东西: (马克，真诚)(约翰，真诚)。

from nltk import word_tokenize, pos_tag, ne_chunk
sentence = "Mark and John are sincere employees at Google."
print ne_chunk(pos_tag(word_tokenize(sentence)))

Answer 1

Spacy 的 POS tagging会比 NLTK 更好。它更快更好。这是您要执行的操作的示例

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)]
