Key: CTAKES-21

Project: cTAKES
Issue Type: Bug
Components: ctakes-drug-ner
Affects Versions: 2.6-incubating
Reporter: Pei Chen
Priority: Minor
Migration from SF Bug Tracker ID: 3560796
DrugNER seems to be able to pick up the signatures for “20 mg Tamoxifen” but
not “Tamoxifen 20mg".
The problem is the code sees ‘Tamoxifen 20 mg’ and ‘Tamoxifen’ as two separate
drugs, since there is a unique Rxnorm cui for each. So, in a sense it’s looking
between mentions for attributes and not finding any. This problem would not be
seen if there was another drug to follow or if strength did not map to a unique
Rxnorm cui.
For instance, if you change the ’20 mg’ to ‘120 mg’ in your example above it
would assign the attributes correctly.
