Re: SUO: OpenCyc Released - concepts/assertions?
David,
That's certainly the way "Classic Cyc" works (SubL, by the way, is a
"Subset Lisp"). I've even written a little SubL myself.
Seeing the Java code in the OpenCyc distribution, I leapt to the conclusion
that OpenCyc was a pure Java re-write of proprietary Cyc.
Oh, well.
