java.lang.Object
  edu.cmu.minorthird.text.AbstractAnnotator
      edu.cmu.minorthird.text.learn.StartEndLengthAnnotator

All Implemented Interfaces:

Annotator, ExtractorAnnotator

public class StartEndLengthAnnotator
extends AbstractAnnotator
implements ExtractorAnnotator

Annotator based on classifiers for start, labels, and length.

Constructor Summary

StartEndLengthAnnotator(BinaryClassifier start, BinaryClassifier end, SpanFeatureExtractor fe, java.util.Map<java.lang.Integer,java.lang.Integer> lengthMap, int totalPosSpans, java.lang.String annotationType)
Create an annotator.

Method Summary

protected void	doAnnotate(MonotonicTextLabels labels) The implementation for this method annotates labels in-line.
java.lang.String	explainAnnotation(TextLabels labels, Span documentSpan) The implementation for this method should explain how annotation would be added to some part of the text base.
SpanFinder	getEndFinder() Return something that finds ends (for debugging).
java.lang.String	getSpanType() The spanType used to encode the spans extracted by the ExtractorAnnotator.
SpanFinder	getStartFinder() Return something that finds beginnings (for debugging).
double	getThreshold()
void	setThreshold(double t)
java.lang.String	toString()
