获取所有下义词的完整列表[重复]

有什么方法可以获得与单个单词相关的下位词的完整列表吗？

relative = wordnet.synsets("relative", pos='n')[0]    
hyponyms = ([lemma.name() for synset in relative.hyponyms() for lemma in synset.lemmas()])

这给了我很多下义词，但是 Wordnet 在线搜索的完整下义词列表中的许多下义词并不在我的列表中。

Use the Synset.closure() https://github.com/nltk/nltk/blob/develop/nltk/corpus/reader/wordnet.py#L503功能：

from nltk.corpus import wordnet as wn

relative = wn.synsets('relative', 'n')[0]
hypos = lambda s:s.hyponyms()

print(list(relative.closure(hypos)))
