Python NLTK中的形容词名词化

• “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

$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
