Description

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.
