All Implemented Interfaces:

Scorer<String>

public class MultiClassChunkEvalStats
extends MultiClassPrecisionRecallExtendedStats.MultiClassStringLabelStats

Calculates phrase based precision and recall (similar to conlleval) Handles various encodings such as IO, IOB, IOE, BILOU, SBEIO, [] Usage: java edu.stanford.nlp.stats.MultiClassChunkEvalStats [options] < filename -r - Do raw token based evaluation -d - Specifies delimiter to use (instead of tab) -b - Boundary token (default is -X- ) -t - Default tag to use if tag is not prefixed (i.e. is not X-xxx ) -ignoreProvidedTag - Discards the provided tag (i.e. if label is X-xxx, just use xxx for evaluation)
