Throws:

org.apache.uima.resource.ResourceInitializationException

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.

getCoveringClass

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

Specified by:

getCoveringClass in class RelationExtractorAnnotator

getCandidateRelationArgumentPairs

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

Description copied from class: RelationExtractorAnnotator

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

Specified by:

getCandidateRelationArgumentPairs in class RelationExtractorAnnotator

createRelation

protected void createRelation(org.apache.uima.jcas.JCas jCas,
                              IdentifiedAnnotation arg1,
                              IdentifiedAnnotation arg2,
                              String predictedCategory)

Description copied from class: RelationExtractorAnnotator

Create a UIMA relation type based on arguments and the relation label. This allows subclasses to create/define their own types: e.g. coreference can create CoreferenceRelation instead of BinaryTextRelation

Overrides:

createRelation in class RelationExtractorAnnotator

Parameters:

jCas - - JCas object, needed to create new UIMA types

arg1 - - First argument to relation

arg2 - - Second argument to relation

predictedCategory - - Name of relation

getRelationCategory

protected String getRelationCategory(Map<List<org.apache.uima.jcas.tcas.Annotation>,BinaryTextRelation> relationLookup,
                                     IdentifiedAnnotation arg1,
                                     IdentifiedAnnotation arg2)

Description copied from class: RelationExtractorAnnotator

Looks up the arguments in the specified lookup table and converts the relation into a label for classification

Overrides:

getRelationCategory in class RelationExtractorAnnotator

Returns:

If this category should not be processed for training return null otherwise it returns the label sent to the datawriter
