Class CRFClassifierEvaluator<IN extends CoreMap>

java.lang.Object
  edu.stanford.nlp.optimization.CmdEvaluator
      edu.stanford.nlp.ie.crf.CRFClassifierEvaluator<IN>

All Implemented Interfaces:

Evaluator

public class CRFClassifierEvaluator<IN extends CoreMap>
extends CmdEvaluator

Evaluates CRFClassifier on a set of data - called by QNMinimizer periodically - If evalCmd is set, runs command line specified by evalCmd otherwise does evaluation internally NOTE: when running conlleval with exec on Linux, linux will first fork process by duplicating memory of current process. So if JVM has lots of memory, it will all be duplicated when child process is initially forked.
