createAnnotatorDescription

public static AnalysisEngineDescription createAnnotatorDescription(java.io.File modelDirectory)
                                                            throws ResourceInitializationException

Deprecated. use String path instead of File. ClearTK will automatically Resolve the String to an InputStream. This will allow resources to be read within from a jar as well as File.

Throws:

ResourceInitializationException

getFeatureExtractors

protected java.util.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 java.lang.Class<? extends Annotation> getCoveringClass()

Specified by:

getCoveringClass in class RelationExtractorAnnotator

getCandidateRelationArgumentPairs

protected java.util.List<RelationExtractorAnnotator.IdentifiedAnnotationPair> getCandidateRelationArgumentPairs(JCas jCas,
                                                                                                    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

ifDependent

private static boolean ifDependent(JCas jCas,
                  EventMention ev1,
                  EventMention ev2)

createRelation

protected void createRelation(JCas jCas,
                  IdentifiedAnnotation arg1,
                  IdentifiedAnnotation arg2,
                  java.lang.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 java.lang.String getRelationCategory(java.util.Map<java.util.List<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
