             Summary: cTAKES handling of fractions in dosage
                 Key: CTAKES-289
                 URL: https://issues.apache.org/jira/browse/CTAKES-289
             Project: cTAKES
          Issue Type: Bug
          Components: ctakes-drug-ner
    Affects Versions: 3.1.1
            Reporter: Pei Chen
            Priority: Minor


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.
Jain
