Subject RE: what dictates full medication mention?

cTAKES annotates all mentions it finds, so if a shorter one is part of a longer one, you are
supposed to get both/all, just as you are seeing with Ibuprofen and Ibuprofen 100MG.

Offhand I don't know why the Drug NER cTAKES is not also creating a org.apache.ctakes.typesystem.type.textsem.MedicationMention
for "Propranolol 40 MG".  It's not creating one for me either.  I'm using DrugAggregatePlaintextUMLSProcessor.xml
And when I look at UMLS via the UTS, I see an rxnorm entry Propranolol 40 MG [A10426756/RXNORM/SCDC/328608]
for C1123553.

Drug NER component uses a lucene index of terms from RxNorm. It's possible that term is missing
from the index.  I can check on that later today or tomorrow if no one else beats me to it.

I would do it using the Luke tool to inspect the lucene index in

Subject: what dictates full medication mention?


I have a quick question.  When I run the cTAKES drugNER module on
"Ibuprofen 100 MG" and "Propranolol 40 MG", I get an annotation for both
Ibuprofen 100MG and Ibuprofen for the first case, but for the second case I
only get Propranolol, by itself.  It does show the strength as 40MG for
Propranolol, but it doesn't create a medication mention with full covered
text as "Propranolol 40 MG".
Both of these have the same semantic type, I noticed ( [T200]).
