that that. The pragmatic layer ovoer the semantic web may simply be
the Revenge of the OOPMen (Object-oriented Programmers).
If
pragmatics as linguistics is about the purpose/intent of speech acts, then in a
computer system, a fully-laden purposeful data structure
comes
with its own methods. If signs are just typed arguments passed among
functions and passing objects is a means to pass
a
purposeful data structure, then Pragmatics On The Web comes down to
object-oriented programming on the top of RDF/CG, not
statistical divination or theory of mind.
If so,
it's a movie we've already seen. It was good on the big screen and
sorta dorky on the little screen, but I'm sure cable will
replay
it as often as they can.

Len,
this is
very interesting. First time I have come across Grice outside of academic,
linguistic circles. What I had read of his I always thought it must be
applicable to ontology reasoning, but never took the thought further. It is
interesting that the Grician contribution is classified as pragmatics, the
classification Peirce gave his own logic.
Thanks (all) for this
thread.
The
fact that "dumb" Bayesian
networks with no semantic formalisms have been
much more successful
than expert systems in classifying spam, and
therefore much more
useful to real people, is perhaps a beacon in this
regard.
There are those who attempt to combine the two
(losing the "purity" of both), each node of an ontology tree computed against
a statistical algorithm.
But the intriguing thing about statistical
analysis is that in some way it is not "dumb", it really is an open question
as to how neural type networks map into brain/human social functioning.
Stochastic process and models of these processes are often givens in
psychological research, i.e. a neural net model may be taken as sufficient to
model peripheral processes to that under investigation.
Ontologies are
convenient ways of organising information that take some of their convenience
from the fact that their structure contains information. But there is no
reason to believe that because an ontology can be generated it is a discovery
of what already exists, on the contrary, it is an intellectual invention that
provides short cuts to implied knowledge in some circumstances. C.S. Peirce
demonstrated the logical necessity of the underlying relationships, not
particular, specific ontologies.
I think that the issues are not of the
complexity of the machine, but the complexity of the user if the user is
human. Methods that may work for machine <-> machine negotiation may not
work for human <-> machine, pragmatically speaking. I think this is an
area for research and clarification.

Given the frequency
of spam, the occasional
misclassification is a low cost event,
strictly
speaking although there is a probability that
I will miss
something important.
Pragmatic systems are learning
systems.
