for DrugAggregatePlantextUMLSProcessor.xml, I am not able to detect the

b) Also I am getting lots of false positives like "performed" as
medication. Can anyone help me with the problem. Also when I load the xml
DrugAggregateCDAUMLSProcessor.xml, I am getting problem following problem.
"org.apache.uima.analysis_engine.AnalysisEngineProcessException"/ Is this
because of UMLS or something ?

c) How secured it is when we authenticate for UMLS credentials with our
documents ? Will my data be shared ?

d) Also does cTakes also use ICD9 tagging ? I am not able to see clear
