Method Summary

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.

Classifier	getClassifier()
SpanFeatureExtractor	getFE() The feature extractor applied to candidate spans.
java.lang.String	getSpanProperty() If non-null, the property used to encode the output of the classifier.
java.lang.String	getSpanType() If non-null, the spanType used to encode the positive predictions of the classifier (which should be a BinaryClassifier).

Method Detail

getFE

public SpanFeatureExtractor getFE()

The feature extractor applied to candidate spans.

getClassifier

public Classifier getClassifier()

getSpanProperty

public java.lang.String getSpanProperty()

If non-null, the property used to encode the output of the classifier.

getSpanType

public java.lang.String getSpanType()

If non-null, the spanType used to encode the positive predictions of the classifier (which should be a BinaryClassifier).

getCandidateType

public java.lang.String getCandidateType()

If non-null, the spanType corresponding to candidate spans to be classified. If null, the document spans will be classified.
