Package edu.stanford.nlp.parser.metrics

Class UnlabeledAttachmentEval

java.lang.Object

edu.stanford.nlp.parser.metrics.AbstractEval

edu.stanford.nlp.parser.metrics.UnlabeledAttachmentEval

All Implemented Interfaces:

Eval

public class UnlabeledAttachmentEval
extends AbstractEval

Dependency unlabeled attachment score.

If Collinization has not been performed prior to evaluation, then it is customary (for reporting results) to pass in a filter that rejects dependencies with punctuation dependents.

Constructor Detail

UnlabeledAttachmentEval

public UnlabeledAttachmentEval(String str,
                               boolean runningAverages,
                               HeadFinder headFinder)

Parameters:

headFinder - If a headFinder is provided, then head percolation will be done for trees. Otherwise, it must be called separately.

UnlabeledAttachmentEval

Method Detail

evaluate

public void evaluate(Tree guess,
                     Tree gold,
                     PrintWriter pw)

Specified by:

evaluate in interface Eval

Overrides:

evaluate in class AbstractEval

makeObjects

protected Set<?> makeObjects(Tree tree)

Build the set of dependencies for evaluation. This set excludes all dependencies for which the argument is a punctuation tag.

Specified by:

makeObjects in class AbstractEval

main

public static void main(String[] args)

Run the Evalb scoring metric on guess/gold input. The default language is English.

Parameters:

args -
