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

问题描述

Penn Treebank 格式不注释名词短语的内部结构，例如

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

(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)

              (NP (DT the) (NN river)))))))

我想提取人头(价格和房子).你知道有什么工具可以做到这一点吗?

推荐答案

Michael Collins 论文(附录 A)包括 Penn Treebank 的 head-finding 规则，这些规则运行良好且不难实施.然而，它们远非完美，因为这不是最简单的任务.

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.
