In the context of doing inference, the knowledge items are
relationships, not just terms
So, for instance,
"Beast inherits from animal with degree .87 and evidence level .99"
is a relationship, which is a knowledge item in the sense I was
intending it in that post.
And, relationships are not just binary of course, there are k-ary
relationships, many of them
predicate-argumentlist relationships.
And then there are abstract relationships between relationships, some
of which are subtle enough
to be expressible only using mechanisms such as quantified variables,
or combinators....
So, the question is how big is the relevant subset of the space of
(2^20)^k k-ary relationships... and
the relevant subset of the space of abstract meta-relationships...

How do you respond to the 20-question argument that there are only
of order 2^20 "knowledge items" ?
