名词短语的查找规则 [英] Head-finding rules for noun phrases

问题描述

Penn Treebank格式不会注释名词短语的内部结构，例如

(NP (JJ crude) (NN oil) (NNS prices))

或

(NP
    (NP (DT the) (JJ big) (JJ blue) (NN house))
    (SBAR
      (WHNP (WDT that))
      (S
        (VP (VBD was)
          (VP (VBN built)
            (PP (IN near)
              (NP (DT the) (NN river)))))))

我想提取人头(价格和房屋).您知道有什么工具可以做到这一点吗?

解决方案

迈克尔·柯林斯论文(附录A)包括宾夕法尼亚州树库的发现规则，这些规则工作得很好并且不难实施.但是，它们远非完美，因为这不是最简单的任务.

大卫·瓦达斯(David Vadas)和詹姆士·柯伦(James Curran)在宾夕法尼亚州树丛中的NP结构方面的工作也可能是相关的:

• David Vadas的网站，带有附加的NP注释:
• 纸张:
  • 将名词短语结构添加到宾州树状银行
  • 在宾州树库中解析名词短语

The Penn Treebank format does not annotate the internal structure of a noun phrase, e.g.

(NP (JJ crude) (NN oil) (NNS prices))

or

(NP
    (NP (DT the) (JJ big) (JJ blue) (NN house))
    (SBAR
      (WHNP (WDT that))
      (S
        (VP (VBD was)
          (VP (VBN built)
            (PP (IN near)
              (NP (DT the) (NN river)))))))

I would like to extract the heads (prices and house). Do you know of any tool that can do this?

解决方案

Michael Collins dissertation (Appendix A) includes head-finding rules for the Penn Treebank that work reasonably well and are not difficult to implement. They're far from perfect, though, since it's not the easiest task.

The work by David Vadas and James Curran on NP structure in the Penn Treebank could also be relevant:

• David Vadas's website with additional NP annotation:
• Papers:
  • Adding Noun Phrase Structure to the Penn Treebank
  • Parsing Noun Phrases in the Penn Treebank
