I'm appealing to your experience. Given two assertions:

  http://xmlns.com/wordnet/1.6/Hoary_Marmot is_a "Hoary Marmot"
  http://xmlns.com/wordnet/1.6/Hoary_Marmot is_a "web page"

Your undertanding of what it means to be a Hoary Marmot (in particular
that all such things belong to each of the following classes of
things: marmots, rodents, gnawing animals, placental mammals,
eutherian mammals, mammals, vertibrates, craniates, chordates,
animals, organisms, living things, animate things, and physical
objects) will lead you to conclude that those assertions are
inconsistent.

I could have made some additional statements to express explicitly
that the set of hoary marmots and the set of web pages are disjoint,
but I didn't bother.

You, the human being, relies on wetware. A machine is going to rely
on...something else. The trick is not to make assertions that you
can't prove, I suppose.

| How might
| my search engine have figure it out for _itself_?

I have no idea.

                                        Be seeing you,
                                          norm
