For those of you who have suffered through my vague and confused uneasiness over the past couple of years, let me assure you: my current position is CLEAR, CONCISE, CONSISTENT. I will state my position in terms of Cyc's Collection, but the principle is the same if you use the RDF/OWL Class. 1. There are two very different, "orthogonal" kinds of relations in a conceptual hierarchy. a. "vertical property" relations -- isu, iss -- for example individual isu class; species iss genus; b. "horizontal bookkeeping" relations -- ismem -- for example individual ismem Individual; Thing ismem Collection; Thing ismem Class; 2. Note that "Thing ismem Collection;" is completely unrelated to statements like Thing isu Collection; (which is false) Thing isu Thing; (which is false) 3. If you run "ke -cyc", you will see that mKE finds a number of such false statements in the Cyc Upper Ontology. # INFO: update_knit: cyc context copied from spo # ERROR: add_unit: same concept(string[20]) <Collection isu Class> # ERROR: add_unit: same concept(string[33]) <CollectionType isu CollectionType> # ERROR: add_unit: same concept(string[29]) <CoreConstant isu CoreConstant> # ERROR: add_species: same concept(string[27]) <CycLTerm iss CycLExpression> # ERROR: add_unit: same concept(string[37]) <Set-Mathematical isu Set-Mathematic al> # ERROR: add_species: not allowed(string[15]) <Thing iss Class> # ERROR: add_unit: not allowed(string[15]) <Thing isu Class> # ERROR: add_unit: not allowed(string[22]) <Thing isu CoreConstant> # ERROR: add_unit: not allowed(string[15]) <Thing isu Thing> 4. I will post my official "correction" http://mKRmKE.net/knowledge/cyc/myCyc.mkr to the official Cyc Upper Ontology http://mKRmKE.net/knowledge/cyc/UpperOntology.mkr on my web site tomorrow.
