cTAKES handling of fractions in dosage

[Ajay Jain]

Hi,
I am running the DrugAggregatePlainTextUMLSProcessor and noticing that cTAKES 
is not handling fractions for medication dosage correctly.  For example,
"Benadryl 1/2 tsp 3 times daily"
produces a MedicationMention with a dosage of 2.  Having tried different 
fractions (1/2, 1/3, 2/4, etc.), apparently the dosage is always set to the 
digit on the right of the '/'.  I am wondering if this is a documented issue 
with cTAKES (I am using cTAKES version 3.1).  Thanks in advance.
