Python NLTK中的形容词名词化

有没有办法使用NLTK获得Wordnet形容词标称化？
例如,对于“快乐”,期望的输出将是“快乐”.

我试图四处搜寻,但找不到任何东西.

谢谢！

• “a happy smile”; “spent many happy
  days on the beach”; “a happy marriage”

  • attribute
    • well-being characterized by emotions
      ranging from contentment to intense
      joy)
    • in a state of well-being)
  • derivationally related form
    • of well-being characterized by
      emotions ranging from contentment to
      intense joy)
    • (emotions experienced when in a state
      of well-being)

剩下的问题是如何以编程方式执行此操作(无需网络抓取).

添加：

wordnet库包装器工具非常强大,它展示了C库接口的广度：

$wn happy
No information available for noun happy
No information available for verb happy
Information available for adj happy
    -antsa      Antonyms
    -synsa      Synonyms (ordered by estimated frequency)
    -attra      Attributes
    -deria      Derived Forms
    -famla      Familiarity & Polysemy Count
    -grepa      List of Compound Words
    -over       Overview of Senses
$wn happy -deria -n1
Derived Forms of adj happy
Sense 1
happy (vs. unhappy)
       RELATED TO->(noun) happiness#1
           => happiness,felicity
       RELATED TO->(noun) happiness#2
           => happiness

所以,从Python的角度来说,你可以对wn命令进行子处理,这有点邋or,或者使用已经内置到NLTK中的wordnet工具.

在ubuntu(可能是debian)上,wordnet库和工具可以方便地使用：

sudo apt-get install wordnet wordnet-dev

唉：

$wn pythonic
No information available for pythonic
