edu.stanford.nlp.trees.CollinsHeadFinder

Implements the HeadFinder found in Michael Collins' 1999 thesis. Except: we've added a head rule for NX, which returns the leftmost item. No rule for the head of NX is found in any of the versions of Collins' head table that we have (did he perhaps use the NP rules for NX? -- no Bikel, CL, 2005 says it defaults to leftmost). These rules are suitable for the Penn Treebank.

May 2004: Added support for AUX and AUXG to the VP rules; these cause no interference in Penn Treebank parsing, but means that these rules also work for the BLLIP corpus (or Charniak parser output in general). Feb 2005: Fixes to coordination reheading so that punctuation cannot become head. @author Christopher Manning
