推荐答案

您可以使用NLTK中的SentiWordNet接口检查英语单词的情感内容.来自 NLTK 的使用.

You can use SentiWordNet Interface in NLTK to check for the emotional content of an English word. Usage from NLTK.

>>> from nltk.corpus import sentiwordnet as swn

>>> list(swn.senti_synsets('breakdown'))
[SentiSynset('dislocation.n.02'),
 SentiSynset('breakdown.n.02'),
 SentiSynset('breakdown.n.03'),
 SentiSynset('breakdown.n.04')]

>>> breakdown = swn.senti_synset('breakdown.n.03')
>>> print(breakdown)
<breakdown.n.03: PosScore=0.0 NegScore=0.25>
>>> breakdown.pos_score()
0.0

0.25
