[bioontology-support] Annotator Plus

[Kuttichi Keloth, Vipina]

Hi,

Is there documentation available for annotator plus specifically for
understanding Negation?

I tried annotating the text "*Neck supple, no lymphadenopathy, no JVD, no
edema*." specifying the options Match longest only, Detect Negation and
using SNOMED CT as the ontology.
I am getting expected results as shown in the attached screenshot.

But when I click on the link for reproducing these results using the
corresponding *REST API call*
this is what I get

**************************************************************************************
As you can see for every concept the negationContext is shown as "AFFIRMED".
I tried with different texts but I am not getting "NEGATED" in any case.
Could you please look into this and let me know what is happening in the
case of API calls?

Thank you.
