Dosage strength is not returned in the response

[AadiMehta]

Hello,

While trying to get the structured clinical data from the text, we have noticed that the drug strength is not parsed by the ctakes. I see that there is the component in the codebase "ctakes-drug-ner".

Is this component enabled by default? or do we have to enable it manually.

Here is the sample snapshot for same text from the CLAMP and CTAKES-REST-SERVICE:

Can you please point me in the right direction.

Thanks.

Hi Did you find a solution for this?

@premanandmanimaran Not sure, but I think you have to enable drug-NER component to get the result
