View In Hierarchy

A pointer used by nombank to identify one or more constituents in a parse tree. NombankPointer is an abstract base class with three concrete subclasses:

  • NombankTreePointer is used to point to single constituents.
  • NombankSplitTreePointer is used to point to 'split' constituents, which consist of a sequence of two or more NombankTreePointer pointers.
  • NombankChainTreePointer is used to point to entire trace chains in a tree. It consists of a sequence of pieces, which can be NombankTreePointer or NombankSplitTreePointer pointers.
