Hi Samir,
Before we talk any further, I'd like to mention that the relation
extractor is a machine learning system. You can read more about it here:
http://jamia.bmj.com/content/early/2013/10/03/amiajnl-2013-001766.full
So if you want to extend it, you'll need some data that annotates the
"affects" relation. Do you have this kind of data?

Hi Pei, Dimitry and any other that may help on
this …
Currently I’m using cTAKES to semantically analyze
a medical question and then try to map it to PICO structure based on different
medical type (relations, NE) identified in the question. I’m interested in
extending
the ctakes-relation-extractor project in order to handle the << affects>>
relation of the UMLS
semantic network.
First of all is that possible?
If yes,
what is the involvement? My plan is:
1) To proceed with the implementation locally and
then check it in to be validated and deployed later (if it’s approved).
2) How ever I’m not very familiar with the subject
matter on how UMLS semantic relations are implemented in cTAKES. Is the <<
affects>>
relation will follow the same logic than LocationOfRelation and DegreeOfLocation?
Which kind of IdentifiedAnnotation that the <<
affects>> relation will relates? It
would be very appreciated if some one guides me on this matter.
Thanks Samir
