                ABSTRACT OF NEXT WEEK'S TINLUNCH
         ``CSLI and Industry: Where do we go from here?''

Almost from the beginning, CSLI has been a collaborative research venture.
Its present links to SRI International and Xerox PARC are particularly close
ones.  But as the Center moves toward the establishment of research policy
and looks to further collaboration with other corporations, a number of
questions arise.  Should we have formal programs such as the relatively
recent Sponsors Program of CIS or the Stanford University Solid-State
Affiliates Program?  Do we want anything so structured?  How actively should
we seek collaboration?  What do we expect to get out of such involvements?
What kinds of agreements regarding proprietary access can and should be
made?  What are the dangers?  What are the benefits?  What have we learned
from the current collaborative relationships?  Not only are these complex
and interesting issues in their own right, their resolution will have direct
ramifications for the work we all do.  Next week's Tinlunch will center
around these and other questions regarding university/industry relations
in general and CSLI/industry relations in particular.

                 CSLI STUDY GROUP ORGANIZATIONAL MEETING
                   Tuesday, November 13, 1984, 1:15 p.m.
                      Conference Room, Ventura Hall

Research on situated language at CSLI currently intersects philosophy, AI/CS
and linguistics.  This research and much work in the field of psychology
share an interest in how finite agents recognize, store and use information
about the world.  Yet, psychology is not fully represented in the
interdisciplinary CSLI effort.  A CSLI study group is now being formed to
discuss issues and research in cognitive and informational processing from
the perspective of psychology, with topics including but by no means
restricted to the psycholinguistic study of language.  One goal is the
exploration of common areas of interest for possible joint research in the
future.  The format of the meetings will be informal discussions.  While
the study group is open to everyone, regular attendance will be necessary
for the working group to build a shared body of knowledge.  Members of the
Psychology Department are especially welcome. (Questions to Marcy Macken:

Place:   Room 381-T, 1st floor Math. Corner.
Time:    Monday November 12, 4:15-5:30 p.m.
         There will be a no-host dinner at a local restuarant following
         the talk.  (Abstract on following page.)

        ABSTRACT OF SEMINAR IN LOGIC AND FOUNDATIONS OF MATHEMATICS

The main aim of the talk is to discuss situations in analysis where ideas
and results of descriptive set theory might be relevant.  In particular,
we will survey a number of old and new results which classify in the
projective hierarchy various natural examples, occuring in analysis, of sets
in Polish spaces (especially from real analysis, differentiation theory and
the theory of trigonometric series).  In case a given set is classified to
be coanalytic (but not Borel) we will be also concerned with the further
problem of finding a coanalytic norm, which assigns in a natural way a
countable ordinal number to each member of the set in question.  This
provides a canonical ranking of the elements of the set and reveals its
underlying hierarchical structure.

              NL--3 MEETING: DISCOURSE REPRESENTATION THEORY

As part of the NL--3 activities for this quarter, I will be giving a
presentation on the basic ideas behind Discourse Representation Theory as
developed by Hans Kamp, on Tuesday, November 27, at 1:15 p.m.  I'll talk
about the uses two which DRSs can be put, and maybe a little about my own
work on anaphora in DRSs, and why that necessitates allowing various
operations that change the representations.  Anyone who is interested is
welcome to attend.                                       ---Peter Sells

             AREA--P1 MEETING: PERCEPTUAL CATEGORIES

Tuesday, November 13, 11:00 a.m. in Conference Room, Ventura Hall.

In our first meeting Arron Bobick, a graduate student in psychology/AI at
M.I.T., will INFORMALLY discuss his thesis topic: ``Growing Natural
Perceptual Categories,'' i.e., how a priori constraints on the types of
uniformities found in the world can serve as an important constraint on the
process of forming (hypothesizing) perceptual categories.  All are invited.
Questions to (Sandy) Pentland at SU-CSLI.
