Class ParserEvaluator

java.lang.Object
opennlp.tools.util.eval.Evaluator<opennlp.tools.parser.Parse>
opennlp.tools.parser.ParserEvaluator
public class ParserEvaluator extends opennlp.tools.util.eval.Evaluator<opennlp.tools.parser.Parse>
This implementation of opennlp.tools.util.eval.Evaluator<opennlp.tools.parser.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.
