Context grabbing VARs -

I don't know if I have the gist of it but consider this AODiagram interpretation of some basics:

If Narwhal is using a concept tree whose nodes could be labeled as (parents of) compatible, group-able, or alternative children, then I could implement code that checks recently mentioned VARs to see if any are found under a parent labeled in one of those ways.
The purpose of this is to manage indefinite words that refer to context (eg 'it', 'both', 'compare', 'choose',...) . "It" and "both" refer to group-able entities. "Both" also refers to compatible entities. "Choose", "What is the difference" refer to alternative entities.
