                                    KR'92
                      Third International Conference on
            Principles of Knowledge Representation and Reasoning

                             Royal Sonesta Hotel
                        Cambridge, Massachusetts, USA

                             October 25-29, 1992

With support from the American Association for Artificial Intelligence, the
European Coordinating Committee on Artificial Intelligence, and the Canadian
Society for Computational Studies of Intelligence; in cooperation with
International Joint Conferences on Artificial Intelligence, Inc.

                                 ABOUT KR'92

The idea of explicit representations of knowledge manipulated by inference
algorithms provides an important foundation for much work in Artificial
Intelligence, from natural language to expert systems.  A growing number of
researchers are interested in the principles governing systems based on this
idea.  Following the successful formula of the two earlier KR conferences,
KR'92 will bring together these researchers in a more intimate setting than
that of the general AI conferences.  In particular, authors will have the
opportunity to give presentations of adequate length to present substantial
results.  Also, a relatively small conference site has again been selected in
order to encourage informal interaction among attendees.

The theme of this year's conference is the relationship between the
principles of knowledge representation and reasoning and their embodiment in
working systems.  Presented papers and invited talks will address the
following important questions:

* What issues arise in applying knowledge representation systems to
  real problems?
* What are the theoretical principles of knowledge representation
  and reasoning?
* How can these principles be embodied in knowledge representation
  systems?

                                  LOCATION

The KR'92 Conference will again be held at the Royal Sonesta Hotel in
Cambridge, Massachusetts, which is located near Harvard University, the
Massachusetts Institute of Technology and the city of Boston.  A block of
rooms has been booked at a special conference rate at the Royal Sonesta and
special discount air fares are available from Delta Airlines.  Details are
explained along with registration information later in this announcement.

			  INVITED TALKS AND PANELS

The Perils of the Real World: Representing Medical Knowledge,
Peter Szolovits-Mass.Inst.of Technology, USA
      I will describe some key representational problems that arise very
naturally in trying to capture medical reasoning.  Particularly
important is the need to solve these problems not in isolation but as a
coherent whole.

"All My Autopsies Have Been Performed on Dead People:" Issues in
Knowledge Representation for Discourse Processing,
Martha E. Pollack-U.Pittsburgh, USA
     Natural-language processing and knowledge representation research
ought to have a symbiotic relationship.  In fact, a large gap exists
between the formal systems developed in the KR community and what is
needed to build natural language systems capable of participating in
discourses.

The DARPA Knowledge Sharing Effort: Progress Report,
Ramesh Patil (Panel Organizer)-USC/Information Sciences Inst., USA
     This panel will report on the following activities, with special
emphasis on the problems encountered and open research issues: an
interlingua for translation between different representation languages
(Richard Fikes, Stanford U.), a uniform syntax and semantics for common
constructs within representation families (Peter Patel-Schneider, AT&T
Bell Labs), a protocol for run-time interchange between system modules,
(Donald McKay, UNISYS), and libraries of domain-specific ontologies
(Thomas Gruber, Stanford U.).

Resolving the Imagery Debate: A Cognitive Neuroscience Perspective,
Stephen M. Kosslyn-Harvard U.,USA
     New information about the brain and the advent of new
brain-scanning technologies have enlivened and may finally resolve an
old debate about the nature of the mental representations that give
rise to the experience of "seeing with the mind's eye."  The
propositional position is that such representations are no different in
kind from those that underlie language.  The depictivist position is
that mental representations of imagery are qualitatively distinct
because they embody spatial extent and have other pictorial properties.

Twelve Years of Nonmonotonic Reasoning Research: Where (and What) is the
Beef?,
Ray Reiter-U.Toronto, Canada
     The talk will assess what I believe has been accomplished since the
landmark Special Issue on Nonmonotonic Reasoning of the AI Journal in
1980.  No one disputes that research on nonmonotonic reasoning has
become a growth industry.  Many do however question what on earth all
this stuff is good for.  I will describe how nonmonotonic theories have
in fact made important contributions not only to various areas of AI,
but also to logic programming, databases, and software specification.
Perhaps most important of all, it has provided a unifying framework for
a wide variety of what had previously been viewed as disparate
phenomena.

                                REGISTRATION

Due to space limitations and the success of earlier KR conferences, early
registration is strongly recommended.

		 FEE SCHEDULE (all fees are in U.S. dollars)

Early: Postmarked before midnight September 24, 1992
        Regular $275

				   BANQUET

The banquet on Tuesday evening, October 27, is optional and reservations
should be included at the time of your registration.

This event includes round trip transportation to Boston's historic
waterfront.  You will board the `Spirit of Boston' for a narrated cruise of
the harbor with its colonial landmarks and spectacular city skyline at dusk.

		      STUDENT HOTEL SUBSIDY APPLICATION

A limited amount of funds have been set aside to subsidize hotel room fees
for students.  This will only apply to doubles (two students per room).  The
subsidy will be from 25% to 50% of one-half of the room rate.  For example,
if you are awarded a subsidy of 25%, the cost of staying at the hotel will be
$50.63 per night (75% of one-half of $135), plus applicable taxes.  Each
applicant will be notified if she or he has been awarded the subsidy and, if
so, the amount of the subsidy.

We urge you to use electronic mail to apply for a subsidy if possible.  To
obtain an electronic version of this form and along with further
instructions, send e-mail to kr92-subsidy@cs.tufts.edu.  (These messages will
not be read; a reply will be sent automatically to the sender.  Send other
e-mail correspondence to kr92@cs.tufts.edu.)

If you cannot apply via electronic mail, or if you do not receive the
electronic form and instructions for some reason, print out the form below,
fill it in and send it via regular mail along with your registration
material.

Applications for student subsidies, via either electronic or regular mail,
must be received by September 10, 1992.  Notification as to whether you will
receive the subsidy, and if so, the amount of the subsidy, will sent by
September 24, 1992 using either electronic or regular mail.
