Throws:

org.apache.uima.resource.ResourceInitializationException

getCoveringClass

protected Class<? extends org.apache.uima.jcas.tcas.Annotation> getCoveringClass()

Specified by:

getCoveringClass in class RelationExtractorAnnotator

classify

public String classify(List<org.cleartk.ml.Feature> features)

Description copied from class: RelationExtractorAnnotator

Predict an outcome given a set of features. By default, this simply delegates to the object's classifier. Subclasses may override this method to implement more complex classification procedures.

Overrides:

classify in class RelationExtractorAnnotator

Parameters:

features - The features to be classified.

Returns:

The predicted outcome (label) for the features.

getFeatureExtractors

protected List<RelationFeaturesExtractor<IdentifiedAnnotation,IdentifiedAnnotation>> getFeatureExtractors()

Description copied from class: RelationExtractorAnnotator

Defines the list of feature extractors used by the classifier. Subclasses may override this method to provide a different set of feature extractors.

Overrides:

getFeatureExtractors in class RelationExtractorAnnotator

Returns:

The list of feature extractors to use.

getCandidateRelationArgumentPairs

protected List<RelationExtractorAnnotator.IdentifiedAnnotationPair> getCandidateRelationArgumentPairs(org.apache.uima.jcas.JCas jCas,
                                                                                                      org.apache.uima.jcas.tcas.Annotation sentence)

Description copied from class: RelationExtractorAnnotator

Selects the relevant mentions/annotations within a covering annotation for relation identification/extraction.

Specified by:

getCandidateRelationArgumentPairs in class RelationExtractorAnnotator
