Achieving YTEX negation in CuisOnlyPlaintextUMLSProcessor

[Jessica Glover <gl...@gmail.com>]

I have noticed that using the AggregatePlaintextUMLSProcessor in
ctakes-ytex-uima results in improved negation detection over the one in
ctakes-clinical-pipeline on my test documents.

I would like to get the same improvement in CuisOnlyPlaintextUMLSProcessor.
I have tried replacing the DictionaryLookupAnnotator, which seemed to be
the determining factor in AggregatePlaintextUMLSProcessor, but when I run
it, I find no IdentifiedAnnotations. Does the YTEX
DictionaryLookupAnnotator depend on an analysis engine I've overlooked? Any
other suggestions?

Thank you,
Jessica G.

CTAKES_HOME\desc\ctakes-ytex-uima\desc\analysis_engine\DictionaryLookupAnnotator.xml
references
CTAKES_HOME\resources\org\apache\ctakes\ytex\dictionary\lookup\LookupDesc_SNOMED.xml,
which limits all dictionary lookups
to org.apache.ctakes.typesystem.type.textspan.LookupWindowAnnotation spans,
which are created by the LookupWindowAnnotator.

You can either add the LookupWindowAnnotator (not sure about its
dependencies), or you can change LookupDesc_SNOMED.xml to use a different
annotation (e.g. Noun Phrase or Sentence).

HTH,
