Class FilteredEval

java.lang.Object

edu.stanford.nlp.parser.metrics.AbstractEval

edu.stanford.nlp.parser.metrics.FilteredEval

All Implemented Interfaces:

Eval

public class FilteredEval
extends AbstractEval

An AbstractEval which doesn't just evaluate all constituents, but lets you provide a filter to only pay attention to constituents formed from certain subtrees. For example, one provided filter lets you limit the evaluation to subtrees which contain a particular kind of node.

childFilteredEval

public static FilteredEval childFilteredEval(String str,
                             boolean runningAverages,
                             TreebankLanguagePack tlp,
                             String childPattern)

Returns an eval which is good for counting the attachment of specific node types. For example, suppose you want to count the attachment of PP in an English parsing. You could create one with PP as the child pattern, and then it would give you p/r/f1 for just nodes which have a PP as a child.
