Hi, I am doing NLP research on some clinical documents using cTAKES and I am a little stuck at a point. I have created a pipeline similar to "AggregateCdaUMLSProcessor" in which i want to use dictionary_lookup "UmlsLookupAnnotator" instead of "DictionaryLookupAnnotatorUmls". The identifiedAnnotation given by UmlsLookupAnnotator does not include Sign/Symptoms, Disease/Disorder or Proceedure Mentions etc. I have done required sofa Mapping in java . The pipeline works fine for plaintext document but doesn;t give the above mentioned annotations for CDA. I have tested the CDA document using AggregateCdaUMLSProcessor and it gives the above mentioned annotations (except MedicationMention which I also need) . Can you give me any suggestion about what can I try or what is wrong? Looking forward to hearing from you.
