All Implemented Interfaces:

org.apache.uima.analysis_component.AnalysisComponent

public class SentenceAdjuster
extends org.apache.uima.analysis_component.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(org.apache.uima.UimaContext aContext)
                throws org.apache.uima.resource.ResourceInitializationException

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

Specified by:

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

Overrides:

initialize in class org.apache.uima.analysis_component.AnalysisComponent_ImplBase

Throws:

org.apache.uima.resource.ResourceInitializationException

See Also:

com.ibm.uima.analysis_engine.annotator.BaseAnnotator#initialize(UimaContext)

process

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

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

Specified by:

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

Throws:

org.apache.uima.analysis_engine.AnalysisEngineProcessException

annotateRange

protected void annotateRange(org.apache.uima.jcas.JCas jcas,
                             String text,
                             int rangeBegin,
                             int rangeEnd)
