> I could see setReferenceRangeNarrative method in LabMention class. Is that the one are you referring? Yes -- that's the setter method generated from the type system: https://svn.apache.org/repos/asf/ctakes/trunk/ctakes-type- system/src/main/resources/org/apache/ctakes/typesystem/types/TypeSystem.xml Feature: referenceRangeNarrative Value type: org.apache.ctakes.typesystem.type.textsem. LabReferenceRangeModifier > Also, what is your suggestion to create new class similar to LabValueFinder? Well, if the LabValueFinder suits your needs, then I'd suggest using its annotations as starting points. Run the LabValueFinder and inspect the LabMentions it creates. If getLabValue() gives you a RangeAnnotation, it's probably the reference range, which the LabValueFinder fell back to because it couldn't find a value. Otherwise, search for RangeAnnotations nearby. You may find various org.apache.uima.fit.util.JCasUtil <https://uima.apache.org/d/uimafit-current/api/org/apache/uima/fit/util/JCasUtil.html> methods useful, e.g. selectBetween, selectPreceding, selectFollowing. In my data, the range could often be found between the LabMention and the LabValue; your data may vary. For a general-purpose annotator, you'd want to make that configurable. Also, make you're getting the RangeAnnotations you expect. Last year, I found it expedient to write a quick-fix regular-expression annotator to pick up decimal ranges like the ones below. It would be more civic-minded to change the annotator that generates RangeAnnotations (the ContextDependentTokenizerAnnotator? Not sure offhand).
