问题描述

我尝试将 Wordnet 用作同义词库，因此我有一个单词列表，我需要为每个单词收集其同义词.我试过了

I try to use Wordnet as a thesarus, so I have a list of words and I need to collect for every word its synonyms. I tried this

from nltk.corpus import wordnet as wn
for i,j in enumerate(wn.synsets('dog')):
    print (j.lemma_names)

此代码给出以下输出

<bound method Synset.lemma_names of Synset('dog.n.01')>
<bound method Synset.lemma_names of Synset('frump.n.01')>
<bound method Synset.lemma_names of Synset('dog.n.03')>
<bound method Synset.lemma_names of Synset('cad.n.01')>
<bound method Synset.lemma_names of Synset('frank.n.02')>
<bound method Synset.lemma_names of Synset('pawl.n.01')>
<bound method Synset.lemma_names of Synset('andiron.n.01')>
<bound method Synset.lemma_names of Synset('chase.v.01')>

但我只想在列表中收集同义词，所以输出将是这样的

But I want to collect in a list only the synonyms, so the output will be like this

['frump', 'cad', 'frank', 'pawl', 'andiron', 'chase']

推荐答案

正如您的输出所示，lemma_names 是一种方法而不是属性.Blow 代码按您的预期工作:

As your output indicates, lemma_names is a method rather than a property. Blow code works as you expected:

from nltk.corpus import wordnet as wn
result = [st.lemma_names()[0] for st in wn.synsets('dog')]
print(result)

输出为:

[u'dog', u'frump', u'dog', u'cad', u'frank', u'pawl', u'andiron', u'chase']

请注意，列表中的项目是 Unicode 字符串.这就是为什么您会在输出中看到领先的 u.

Please note that the items in the list are of Unicode string. This is why you see the leading u in the output.
