python - 使用 Wordnet Synset 的定义方法未获得所需的输出

Question

 from nltk.corpus import wordnet 
 syn=wordnet.synsets('cookbook')[0]
 print syn.definition

预期输出:

'a book of recipes and cooking directions'

实际输出:

bound method Synset.definition of Synset('cookbook.n.01')

我无法查明我的代码中导致实际输出与预期输出之间存在差异的错误。

Answer 1

>>> from nltk.corpus import wordnet as wn
>>> wn.synsets('dog')[0]
Synset('dog.n.01')
>>> wn.synsets('dog')[0].definition
<bound method Synset.definition of Synset('dog.n.01')>
>>> wn.synsets('dog')[0].definition()
u'a member of the genus Canis (probably descended from the common wolf) that has been domesticated by man since prehistoric times; occurs in many breeds'

这是因为Synset 对象属性已更改为Synset 函数，参见https://github.com/nltk/nltk/commit/ba8ab7e23ea2b8d61029484098fd62d5986acd9c
