python - Python NLTK 中的形容词名词化

Question

有没有办法使用 NLTK 获取 Wordnet 形容词名词化？ 例如，对于happy，所需的输出将是happiness。

我试图四处挖掘，但找不到任何东西。

Answer 1

快速而肮脏的答案是 wordnet does this already :

• <adj.all>S: (adj) happy (enjoying or showing or marked by joy or pleasure) "a happy smile"; "spent many happy days on the beach"; "a happy marriage"

  • attribute
    • <noun.state>S: (n) happiness, felicity (state of well-being characterized by emotions ranging from contentment to intense joy)
    • <noun.feeling>S: (n) happiness (emotions experienced when in a state of well-being)
  • derivationally related form
    • <noun.state> W: (n) happiness [Related to: happy] (state of well-being characterized by emotions ranging from contentment to intense joy)
    • <noun.feeling> W: (n) happiness [Related to: happy] (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 库包装工具非常强大，并且演示了 C 库接口(interface)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

因此，从 Python 角度来说，您可以对 wn 命令进行子处理，这有点草率，或者使用 NLTK 中已内置的 wordnet 工具。

在 ubuntu(大概还有 debian)上，可以通过以下方式方便地使用 wordnet 库和工具:

sudo apt-get install wordnet wordnet-dev

唉:

$ wn pythonic
No information available for pythonic
