because here the conditional instantiation-meta-rule is in the following

with meaningful atoms.

 What if i want to get inferences out of Criminal.scm automatically,
which is in the form of R2L  and without  hard-coding variables? i.e.
 (KB without variables)

Ah, so you want for instance to either tell the system

"What croaks and eats flies is a frog"

or have it learn it from experience and such, instead of hard coding it in the KB, right?

You're right, hard-coding everything is not practical. These examples are more like toy tests than real world examples. The plan is to have most of these learned or extracted from the web, or such. We'll still hard code some stuff, things that are fundamental and hard to learn like mathematics, amongst other things.

I'm not extremely familiar with the NLP code, but I think it can already produce such knowledge (probably as implication links without variables, but as explained here http://wiki.opencog.org/w/ImplicationScopeLink#PLN_Semantics these are equivalent to implication scopes).
