Field Detail

eventFeatureExtractors

protected List<org.cleartk.classifier.feature.extractor.simple.SimpleFeatureExtractor> eventFeatureExtractors

The list of feature extractors that will be applied directly to the Event annotation. Subclasses should override initialize(org.apache.uima.UimaContext) to fill this list.

contextExtractors

protected List<org.cleartk.classifier.feature.extractor.CleartkExtractor> contextExtractors

The list of feature extractors that will be applied to the Event annotation, with a Sentence window. Subclasses should override initialize(org.apache.uima.UimaContext) to fill this list.

Constructor Detail

EventAttributeAnnotator

public EventAttributeAnnotator()

Method Detail

getDefaultValue

protected abstract OUTCOME_TYPE getDefaultValue()

The attribute value that should be considered as a default, e.g. "NONE". When the attribute value is null in the CAS, this value will be used instead. Additionally, when the classifier produces this value, no attribute will be added.

Returns:

The default attribute value.

getAttribute

protected abstract OUTCOME_TYPE getAttribute(org.cleartk.timeml.type.Event event)

Get the attribute value from the Event annotation. Typically this will be by calling something like Event.getTense(). If this method returns null, getDefaultValue() will be called to produce an appropriate attribute value.

Parameters:

event - The Event annotation whose attribute is to be retrieved.

Returns:

The selected attribute value.

setAttribute

protected abstract void setAttribute(org.cleartk.timeml.type.Event event,
                                     OUTCOME_TYPE value)

Set the attribute value on the Event annotation. Typically this will be by calling something like Event.setTense(String). This method will not be called if the value is equal to getDefaultValue().

Parameters:

event - The Event annotation whose attribute is to be set.

value - The new attribute value.

initialize

public void initialize(org.apache.uima.UimaContext context)
                throws org.apache.uima.resource.ResourceInitializationException

Specified by:

initialize in interface org.apache.uima.analysis_component.AnalysisComponent

Specified by:

initialize in interface org.uimafit.factory.initializable.Initializable

Overrides:

initialize in class org.cleartk.classifier.CleartkAnnotator<OUTCOME_TYPE>

Throws:

org.apache.uima.resource.ResourceInitializationException

process

public void process(org.apache.uima.jcas.JCas jCas)
             throws org.apache.uima.analysis_engine.AnalysisEngineProcessException

Specified by:

process in class org.apache.uima.analysis_component.JCasAnnotator_ImplBase

Throws:

org.apache.uima.analysis_engine.AnalysisEngineProcessException
