The critical problem is how to create a tool which provides semantics in
a holistic fashion *for computers*. Would someone care to take a stab
at characterizing the nature of such a tool?
</Quote>
I attended an excellent presentation by your colleague Leo Obrst Wed.
evening, and your quote "Everything affects everything else, and you
have to understand the whole web of interactions." reminds me of one
aspect that we discussed at the presentation: The aspect of agents
learning new behaviors through interactions over time.
So I would offer that this is one characteristic of such a tool.
Kind Regards,
