Hello all,

I have noticed a common theme in our notes where a list of conditions are 
listed with yes/no indicators, like this:

Hyperlipidemia:  Yes
Hypercholesterolemia:  Yes
Chronic Renal Insufficiency:  N/A
Chronic Renal Failure on Dialysis:  No
Acute Renal Failure:  Yes
Family History of CAD:  No

This is an area where good negation detection is important but I haven't very 
good results. The sentence segmentator sees this as 12 separate sentences, but 
I would think proper behavior would be to consider this as 6 sentences 
(breaking sentences on line break but not on colons). I suspect this is why the 
negation detection is not working well here, but I'm not well-versed in how the 
negation annotator works. Can anyone recommend a way to get better results here?

I have tried a few variants of the AggregatePlaintextFastUMLSProcessor and 
AggregatePlaintextUMLSProcessor with no improvements.

Thanks,
Sean
