			 NEXT WEEK'S TINLUNCH
	      The Anatomy and Layers of Lexical Meaning
			   Julius Moravcsik

I will sketch and illustrate both the theory of lexical meaning that
is contained in my forthcoming book THOUGHT AND LANGUAGE, and explain
why within this theory -- apart from indexicality -- we need to posit
three layers of meaning/reference.  This account has some links with
Winograd's notion that the determination of extension for most terms
is a partly normative enterprise.  I will then sketch a number of
projects that arise out of this work.  Some of these concern
psycholinguistics, i.e., empirical work -- both developmental and
synchronic -- concerning the confirmation or disconfirmation of mental
representations posited by my theory.  Others involve more detailed
work on certain parts of the lexicon, including relations to syntax.
Finally, I will briefly indicate how this program involves group work,
and how it could lead to grant proposals of the sort Stanley Peters
urged us to think about.

		       NEXT WEEK'S CSLI SEMINAR
		      Models of Rational Agency 4
	  Michael Bratman, Martha Pollack, Stan Rosenschein

We will continue our discussion of issues in resource-bounded
practical reasoning, focusing on the relationships between the various
models discussed in the first three meetings.

			SYMBOLIC SYSTEMS FORUM

		   Friday, 13 October, 3:15, 60:61G
    
Martin Kay will discuss his research on machine translation.  The
basic goal of machine translation is to develop a computer program to
translate from one natural language to another.  In order to do this,
various theories of language need to be developed, which can be
programmed into a computer.

	    COMMONSENSE AND NONMONOTONIC REASONING SEMINAR
	      A Survey of Formal Nonmonotonic Reasoning

			 Stanford University
		       (val@sail.stanford.edu)
	  Monday, 16 October, 3:15, Margaret Jacks Hall 252

The Commonsense and Nonmonotonic Reasoning Seminar is a forum in which
we discuss current research and open problems related to the logical
foundations of AI, with a special emphasis on commonsense reasoning
and knowledge, formal nonmonotonic reasoning, and foundations of logic
programming.

This quarter, we are planning to include a few introductory lectures
on these subjects, for the benefit of those who are new to this area
of AI.  This will be the first meeting in the series.  A basic
knowledge of logic will be assumed.

In my current research project -- the one that brought me out here --
I am inquiring how intellectual work is influenced by, and is
influencing, the use of advanced personal (computerized) workstations.
I am doing this by studying what is actually going on during the
working days of individuals.  Intellectual work is understood here as
an elaboration of knowledge so that one becomes able to talk and write
about this knowledge.

The inquiry is supposed to result in systematical descriptions and
concomitant theory-building about the dynamical relation between use
of computerized tools and intellectual work.  Inquiries of this type
might create some important conditions for future intellectual life.

In my presentation, I shall briefly describe this project and its
"context," i.e., the larger research program that it is a part of, the
subjective motivation for it, its background or history in my previous
research, and its current state.
