    Why are there no low level facts in the Cyc KB? For example "A Redwood Tree is tall" or maybe that should be something like "ConceptOfRedwoodTree is tall".

      low level facts

      Well, a Concept can't be tall. But in general, most of Cyc is made up of type-level or category-level assertions. I would expect Cyc to have facts like "On average, redwoods grow to heights of 275 to more than 300 feet" (according to http://www.americanparknetwork.com/parkinfo/sk/flora/compare.html )
      and then in a particular microtheory have facts about "tall" that could be used to see if a redwood tree is tall or not.  (My niece is tall, compared to any other kindergarteners, but not next to a professional basketball team).
