Subject RE: specificity in selecting EntityMentions when using AggregatePlaintextUMLSProcessor

I don't know if this is exactly what you want, but you can use the hyperSql ( http://hsqldb.org/
) database tool to perform searches on the umls dictionary used by cTakes.  
For instance " select * from UMLS_MS_2011AB where FWORD = 'CIN' " will provide all the available
terms starting with CIN.  In the result you'll see that there is no term "CIN I", and you'll
also see that the only listing from ICD9 is for "CIN III" [C0851140, T191, MTHICD9 233.1]

If you want an icd9 code that isn't in the cTakes umls dictionary then you can find it online
... but that won't do you much good wrt cTakes.

Thanks for looking into this, it's been puzzling me.

On another note, I know the cTAKES dictionary uses ICD9, but I'm not familiar with how to
access that information: In the example I've described below, where would I locate the ICD9
for a specific entity?

Thank you

Ted

You're right, it should have gotten "CIN I"- that's a strange one, probably needs to be debugged/looked
into further...
