opennlp.tools.parser.ParserEvaluator

public class ParserEvaluator
extends Evaluator<Parse>

This implementation of Evaluator<Parse> behaves like EVALB with no exceptions, e.g, without removing punctuation tags, or equality between ADVP and PRT, as in COLLINS convention.

To follow parsing evaluation conventions (Bikel, Collins, Charniak, etc.) as in EVALB, options are to be added to the ParserEvaluatorTool.
