I followed the directions in the tutorial PDF for making the pull request for a new BEP - I think I may have deleted the template.

I like the relationship proposal and like how it handles ambiguous correlations, but I prefer to not have an abbreviation for it - at least 'no' doesn't work for me when reading through a sample relationship.

agree that 'no' does not work as an abbreviation

Also agree that no is a bad abbreviation. I think cor is the abbreviation for the non-directional correlation relationship, so maybe noCor?

What do you guys think about the idea of "negative" knowledge as a more general concept?

There's already the causesNoChange relationship, which is effectively the negative of regulates. noCorrelation would be the negative of the correlation relationship.

I think it's the case that there are a lot of times there is a "negative" version of a statement (even direct and causal relations) in the literature, but we don't curate it because it's just not that useful. BEL isn't always oriented towards utility, but rather just encoding what's possible. Conversely, I would imagine representing negative knowledge in a network would be difficult, and so would reasoning over it.
