推荐答案

尽管WordNet是查找同义词的好资源，但必须注意其局限性，这是NLTK库中python API的示例:

Although WordNet is a good resource to start for finding synonym, one must note its limitations, here's an example with python API in NLTK library:

首先，单词具有多种含义(即感觉):

Firstly, words have multiple meanings (i.e. senses):

>>> from nltk.corpus import wordnet as wn
>>> wn.synsets('nice')
[Synset('nice.n.01'), Synset('nice.a.01'), Synset('decent.s.01'), Synset('nice.s.03'), Synset('dainty.s.04'), Synset('courteous.s.01')]

要访问单词的正确含义，您需要在给定上下文的情况下知道单词的正确含义.

And to access the correct sense of a word, you will need to know the correct sense of a word given a context.

>>> wn.synset('nice.a.01').definition()
u'pleasant or pleasing or agreeable in nature or appearance'

您可以尝试使用Word Sense消歧软件，但它们并不完美(请参阅

You can try Word Sense Disambiguation software but they are not perfect (see Anyone know of some good Word Sense Disambiguation software?). Even if you know the sense of the word, the entries of wordnet are limited. You cannot expect much:

>>> wn.synset('nice.a.01').lemma_names()
[u'nice']
>>> wn.synset('nice.a.01').similar_tos()
[Synset('good.s.06'), Synset('pleasant.s.02')]
>>> [i.lemma_names() for i in wn.synset('nice.a.01').similar_tos()]
[[u'good'], [u'pleasant']]
