There are multiple differences between these systems.

* CYC uses crisp boolean logic, and facts are entered by humans into its
knowledge-base.

* NARS uses a certain kind of fuzzy, imprecise logic, combining float pt
values using certain specific formulas.  I'm not sure how they build their
knowledge base -- but I believe that facts are extracted by reading text.

* OpenCog uses a probabilistic logic, combining float pt values using
certain specific formulas.  However, I designed the system so that it
should be "easy" to play with different kinds of formulas -- i.e. you could
implement the NARS formulas in the opencog framework, and this should be
fairly easy to do.  Ben dislikes the NARS formulas, and perhaps he's right
that the PLN formulas are better. I don't care, because the software allows
these formulas to be tweaked, and they will be, in the upcoming years.

OpenCog builds its knowledge base by reading text, i.e. "by learning",
although its ability to do so is still very primitive and crude and
broken-ish.

CYC probably "knows" a lot about cats, because in the last 30 years, a
bunch of humans have probably coded a lot of knowledge about cats into the
CYC knowledge-base.   I doubt it can solve the box+cats+mice problem,
though.

NARS -- no idea how much it knows about cats.

OpenCog -- we do not have any publicly available knowledgebase for
OpenCog.  We've build a few, over the years, and there's probably something
about cats in some of them, maybe.  We haven't focused on accumulating a
knowledgebase, because we haven't had the infrastructure to do much with
one.  I hope this will change "real soon now"....
