Subject Re: Achieving YTEX negation in CuisOnlyPlaintextUMLSProcessor
Date Mon, 04 Jan 2016 11:27:36 GMT
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).
