Package opennlp.tools.parser

## Class ParserEvaluator

- java.lang.Object
- - opennlp.tools.util.eval.Evaluator<Parse>
  - - opennlp.tools.parser.ParserEvaluator

-     public class ParserEvaluator
      extends Evaluator<Parse>

  This implementation of `Evaluator` 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`.
