- All Implemented Interfaces:
public class TreeCollinizer
- extends java.lang.Object
- implements TreeTransformer
Does detransformations to a parsed sentence to map it back to the
standard treebank form for output or evaluation.
This version has Penn-Treebank-English-specific details, but can probably
be used without harm on other treebanks.
Returns labels to their basic category, removes punctuation (should be with
respect to a gold tree, but currently isn't), deletes the boundary symbol,
changes PRT labels to ADVP.

- Description copied from interface:
- Does whatever one needs to do to a particular tree.
This routine is passed a whole
Tree, and could itself
work recursively, but the canonical usage is to invoke this method
Tree.transform() method, which will apply the
transformer in a bottom-up manner to each local
and hence the implementation of
merely examine and change a local (one-level)
- Specified by:
