java.lang.Object

edu.stanford.nlp.parser.metrics.LeafAncestorEval

public class LeafAncestorEval
extends Object

Implementation of the Leaf Ancestor metric first described by Sampson and Babarczy (2003) and later analyzed more completely by Clegg and Shepherd (2005).

This implementation assumes that the guess/gold input files are of equal length, and have one tree per line.

TODO (spenceg): This implementation doesn't insert the "boundary symbols" as described by both Sampson and Clegg. Need to add those.
