JCasAnnotator_ImplBase

org.apache.ctakes.smokingstatus.ae.SentenceAdjuster

public class SentenceAdjuster
extends JCasAnnotator_ImplBase

UIMA annotator that uses some patterns and some rules about those patterns to adjust certain annotations. This annotator was extended to handle sentence boundaries for the Smoking status classification: Example: "Tobacco: none" has two sentences as detected by the sentence boundary detector. This annotator merges them into one sentence to enable correct negation detection.

Method Detail

initialize

public void initialize(UimaContext aContext)
                throws ResourceInitializationException

Performs initialization logic. This implementation just reads values for the configuration parameters. This method is not invoked for every document processed.

Throws:

ResourceInitializationException

configInit

private void configInit()
                 throws AnnotatorContextException

Sets configuration parameters with values from the descriptor.

Throws:

AnnotatorContextException

process

public void process(JCas jcas)
             throws AnalysisEngineProcessException

Invokes this annotator's analysis logic. Invoked for each document processed.

Throws:

AnalysisEngineProcessException

                 java.lang.String text,
                 int rangeBegin,
                 int rangeEnd)
                      throws AnnotatorContextException

A utility method that annotates a given range.

Throws:
