nltk-同义词|反义词示范

前提是需要下载nltk数据集！

import nltk
nltk.download()

代码如下:

from nltk.corpus import wordnet as wn

l=[]
for synset in wn.synsets('function'):
   print(synset.lemma_names())
   for i in synset.lemmas():
       l.append(i.name())
print('\n\n*******function同义词集合如下：')
print(l)

print('\n\n-----------------*******good同义词、反义词集合如下：')
synonyms =[]
antonyms = []
for syn in wn.synsets("good"):
    for l in syn.lemmas():
        synonyms.append(l.name())
        if l.antonyms():
            antonyms.append(l.antonyms()[0].name())

print(set(synonyms))
print(set(antonyms))

输出结果：

['function', 'mathematical_function', 'single-valued_function', 'map', 'mapping']
['function', 'purpose', 'role', 'use']
['function', 'office', 'part', 'role']
['function']
['function']
['affair', 'occasion', 'social_occasion', 'function', 'social_function']
['routine', 'subroutine', 'subprogram', 'procedure', 'function']
['function', 'work', 'operate', 'go', 'run']
['serve', 'function']
['officiate', 'function']


*******function同义词集合如下：
['function', 'mathematical_function', 'single-valued_function', 'map', 'mapping', 'function', 'purpose', 'role', 'use', 'function', 'office', 'part', 'role', 'function', 'function', 'affair', 'occasion', 'social_occasion', 'function', 'social_function', 'routine', 'subroutine', 'subprogram', 'procedure', 'function', 'function', 'work', 'operate', 'go', 'run', 'serve', 'function', 'officiate', 'function']
