Maybe. That's a possibility. Have not yet thought about it much. So let me blather a bit. Clearly, NearLink, BigLink is superior to (GPN "scm:is-near") and (GPN "scm-is-big") because one could write down some reasoning rules "if looks-small and far-away then maybe its big" ... but this would be a chore. You could hand-write a few, but then it gets buggy and complex. Ideally, want to learn these, somehow. Ideally, this could be done in some "extensible" way, without defining new atom types. So that I don't have to have atom types just to add a new preposition. So maybe use GPN's, but then "hide" them behind "well-known" DefinedPredicateNodes. Since they're defined, they could be used for reasoning. I dunno. I still don't really know how to do reasoning ... Ben asked me to think about this a few months ago, I'm trying to clear my backlog of unfinished tasks, but haven't gotten far yet. -- Linas -- cassette tapes - analog TV - film cameras - you -- You received this message because you are subscribed to the Google Groups "opencog" group.
