[jira] [Commented] (CTAKES-129) Populate the Drug NER named entity confidence attribute

["Sean (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CTAKES-129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13564525#comment-13564525 ] 

Sean commented on CTAKES-129:
-----------------------------

The code for implementing this function was not removed, but rather not extended to populate the 'MedicationEventMention' with the v2.5 revisions. A simple addition now allows this attribute to get updated correctly.

> The presence of the other drug signature elements would ramp up the value of the confidence from 0 to approximately .95 depending upon the types of drug related attributes associated with the mention. 
> Any drug-related named entity will be assigned a base value of 0.05 for the Confidence initially; however this value will be set to 0.15 if there is an adjacent Strength discovered. Additionally 0.05 will be added if the presence of the ‘Dosage’ attribute is determined. This value will increase with the addition of other drug elements if discovered. ‘Confidence’ will increase by a factor of 1.3 if Form, Route, or Duration attributes are found, and it will increase by a factor of 1.5 if Frequency and Frequency Unit are discovered.  The maximum confidence would be just under 1.0 (0.989 = (0.5 +0.15) x 1.3 x 1.3 x 1.3 x 1.5 x 1.5) in the event that all elements of the drug named entity were discovered.
