Subject: IRList
Hello Ed, The last IRList I got was Issue #21 of April 23. Has it stopped
to appear, or did subsequent issues get lost in the mails -- I wonder...
Regards, Aviezri S. Fraenkel.
[Note: Thank you for alerting me to mail problems! I had sent out issues 22
and 23 in the interim but some mishap must have occurred during distribution
after the message left here. I sent both out again last week, and am still
getting error messages (about this second try) back about mailer failures at
some sites - but I think this second attempt will make it through eventually.
Please let me know, folks, if you don't have issues 1-24 of Volume 2, and I
will retransmit any missing files as needed. - Ed]

Subject: diff marks
Do you know of any software that finds significant
differences between text files. It is fairly easy
to get nroff, etc. to find differences, but these
could be changed spelling, a single new word,
punctuation. We need to be able to compare two
versions of a document and "mark" significant
differences. Mike Lesk knew of nothing.
This would make an interesting research topic
for someone.
Has your ir network disappeared. This would be
a good question for it. Also are there
any other nets that I could send this out on.
Donna
[Note: nlm-vax had mail problems too which have since been resolved
and they should now have received the various issues they missed.
Regarding the 'diff' problem, it sounds like an interesting and useful
topic to study. One solution might be to take the UNIX 'diff' approach,
but on a word rather than line level, with spelling correction or other
inexact matching techniques added in. Does anyone have something
working to do this? - Ed]

Hi! I got your Reply of the 5th May. Addresses seem to work now
Hanspeter Giger
[Note: In issues 15-18 was discussion of contacting Hanspeter Giger.
We now finally have made contact and he is on the distribution list
thanks to help by several people. - Ed
PS - Can anyone give me an ARPANET-type address to reach
maisel@sds.mfenet - he also wanted to be added to IRList but
none of my attempts to find 'sds' have succeeded.]

DIGITAL TYPOGRAPHY: ART, SCIENCE, AND TECHNOLOGY
Richard Rubinstein, Digital Equipment Corporation
150 Locke Drive - LM04/H4, Marlboro, MA 01752
Digital typography is using computers to present text on
screens and paper. Doing this well, producing high-quality
images that people read easily, calls for an admixture of
three disparate disciplines. The first, typography, is a
traditional art encompassing aesthetic knowledge. Psychol-
ogy offers knowledge of perception, and the means of objec-
tive evaluation. And computer technology provides the vehi-
cle for delivery of letterforms, economically and upon
demand.
The knowledge of these three specialties is expressed in
three vastly different languages. Typographers know a great
deal about letterforms, readability, effective layout and so
on, but they say these things in terms that are not very
familiar or useful to the engineers. By contrast, psycholo-
gists have measurements that may be hard to relate to the
real world of reading books and screens. Historically, read-
ing experiments have not been typographically sophisticated.
And engineers have been accused of just building systems
without talking to anyone else, user or expert.
I am working to convert typographic knowledge into princi-
ples, data, and algorithms that engineers can use directly
in the design of computer systems. I will present a number
of typographical conjectures that I believe psychological
research may illuminate. I will present data that I have
collected that bear on these conjectures.
The result of research spanning these three disciplines
could be algorithms that would dramatically improve the
quality of machine-made text, and a better understanding of
the role of typographic quality in the effective presenta-
tion of text.

USER MODELS AND THE AUTOMATIC SELECTION OF ARTICLES
FOR AN ELECTRONIC NEWSPAPER
Bob Allen, Bell Communications Research
445 South Street, Morristown, NJ 07960
The potential for automatic modelling of people's prefer-
ences for news stories was examined in several experiments.
One study showed that predictions were easy to make in terms
of feature articles and sections of the newspaper that sub-
jects read. However, a second study showed that it is rela-
tively difficult to predict specific news articles that will
read. Overall, the results suggest possible problems in the
wide-spread application of user models. Finally, the rela-
tionship betweeen computer user models and psychological
models which make predictions about people (e.g., attitude
and personality models) is discussed.
Have a pleasant summer. No meeting in August.
See you in September!

IJCAI-89 Site Selection and Officer Election
The Trustees of the International Joint Conferences on Artificial
Intelligence, Inc. are pleased to announce that IJCAI-89 will be held
20-26 August 1989 in Detroit, Michigan, USA. Wolfgang Bibel, Technical
University of Munich, has been elected Conference Chair; Sri
Sridharan, BBN Laboratories, has been elected Program Chair; and Sam
Uthurusamy of General Motors Research Laboratories has been appointed
to chair the Local Arrangements Committee. Don Walker, Bell
Communications Research, the IJCAII Secretary-Treasurer, will also
serve as Secretary-Treasurer for the conference.
IJCAI-89 will be cosponsored by the American Association for Artificial
Intelligence. All conference activities will be coordinated through
the AAAI Office by Claudia Mazzetti, Executive Director of the AAAI,
who will provide direct support for the IJCAI-89 Conference Committee.
In accordance with customary practice for IJCAI conferences held in
North America, the AAAI will also arrange the tutorial and exhibit
programs at the meeting.

KNOWLEDGE, COMMUNICATION, AND TIME
Van Nguyen
IBM Thomas J. Watson Research Center
(Joint work with Kenneth J. Perry)
Abstract
The role that knowledge plays in distributed systems has come under
much study recently. In this talk, we re-examine the commonly
accepted definition of knowledge and examine how appropriate it is for
distributed computing. Motivated by the draw-backs thus exposed, we
propose an alternative definition that we believe to be better suited
to the task. This definition handles multiple knowers and makes
explicit the connection between knowledge, communication, and time.
It also emphasizes the fact that knowledge is a function of one's
initial knowledge, communication history and deductive abilities. The
need for assuming perfect reasoning is mitigated.
Having formalized these links, we then present the first proof
system for programs that incorporates both knowledge and time. The
proof system is compositional, sound and relatively complete, and is
an extension of the Nguyen-Demers-Gries-Owicki temporal proof system
for processes. Suprisingly, it does not require proofs of
non-interference (as first defined by Owicki-Gries).

LEARNING TO CONSTRUCT ABSTRACTIONS
Rick Lathrop
MIT AI Lab
One useful trait of an intelligent agent is to construct higher-level
abstractions from a mass of detailed low-level information. This talk
will explore one way an agent might be taught how to construct such
abstractions, and why it might be a useful or interesting for an agent
to do so. A main motivation is the possibility of the use of these
abstractions to see similarities (between situations) that are
obscured by the mass of irrelevant details at the lower level.
Preliminary examples from the Rieger (causal) mechanism world, VLSI
circuit analysis, and protein structure analysis will be discussed.
