Subj: delay in IRlist
Sorry folks, but machines do break down! We have had a series of hardware
problems since the last issue. The VAX I usually compose issues on is
still down, so please bear with the current layout.
Please keep submitting articles - eventually they will get out! - Ed
PS Since PSUVM will be down 8pm Nov. 27 to 8pm Nov. 29, some BITNET
messages may not get through from up north at that time.

Subject: Keyword in context
Krovetz suggests using the Unix `ptx' command for generating KWIC
indices. Unfortunately, ptx (Unix 4.2) does not solve the problem:
ptx only provides the context on the same source line; both
pre-formatting and post-formatting are in general needed to deal with
punctation and layout gracefully; it does not give an error indication
for over-long input lines.
In short, ptx is fine for generating the index to the Unix manual, but
not sufficiently robust or general-purpose for KWIC indexes of
continuous texts.

Subj: do you know whether Concept Dictionary of English is available?
Ed,
Julius Laffal wrote a book called, "The Concept Dictionary of English,"
Do you know whether that is available in machine readable form? How
could I find out? Is there an index available of machine readable
texts?
John Roach (roach%vpi@csnet-relay.arpa)
[Note: The Oxford Text Archive has an index of its holdings but they
do not have that particular dictionary. They do have the Collins and
Oxford Advanced Learner's dictionaries - I am working now on building
a NL lexicon from them. Does anyone have a pointer to the above
mentioned dictionary or index? - Ed]

Subject: Seminar announcements
I am writing all of you because you have been kind enough to
contribute seminar announcements to various mailing lists recently. I
find these announcements to be very valuable, and I appreciate your
efforts in publishing them.
A suggestion I should like to make, however, is that these
announcements could be even more useful if an electronic as well as a
mailing address could be provided for the speakers. I have often
wanted to get in contact with the speakers, and in general have had to
guess at a net address (the Arpanet registry is far from complete and
I know of no systematic directory on other networks).
I realize that this is not in general easy--ideally, those organizing
the practical aspects of the seminar could collect this information
and include it in their announcements. (Do departmental adminstrators
currently recognize the value of asking for electronic addresses?)
But until that happy day, we can only hope for partial information
when it is easy to come by.
Thanks again for your efforts.

[Note: please do, at the bottom of all submissions, give one or more
electronic mail addresses. If possible, do so in relation to BITNET,
the Internet, and UUCPnet since it is sometimes hard to figure out
proper return addresses. Thanks! - Ed]

Subject: Discussion topics
As moderator of IRList you offer a number of interesting topics for
discussion. How about discussion regarding the principles of communication?
Our course in experimental networking would benefit from such a topic - -
know of any interested parties?

ANNOUNCEMENT
OF A
GRADUATE PROGRAM IN COMMUNICATION
Department of Communication
University of California, San Diego
The faculty of the Department of Communication at the University of California,
San Diego invites applications from students wishing to pursue a Ph.D. in
Communication.
As a faculty we seek to combine previously separate modes of analysis from the
humanities and social sciences to explore the structure, content and methods
of the new discipline of communication. The graduate program is conceived as
a blending of the critical tradition of European communication research with
the empirical tradition of American scholarship.
The study of communication at UCSD is unique in several ways. The program
places major emphasis on historical and comparative approaches to
mediated human activity in all its manifestations. The graduate curriculum
is organized around an explicit framework for understanding communicative
phenomena. This framework is comprised of three perspectives:
1) communication as a social force, 2) communication and culture, and
3) communication and the individual. The first concentrates on the
increasing importance of information and information technologies in
American society and on the global political-economic consequences of media
practices. The second involves the analysis of culture, using traditions
from literature, folklore, and anthropology to focus on questions of
interpretation and meaning. The third involves examination of the individual
as socially constituted through language and other media. The program also
emphasizes problems of methodology including offers a production component
in which students and concretize and evaluate this theoretical work.
The deadline for receipt of applications is February 1, 1986 for those
seeking financial assistance. Final application deadline for all others
is March 1, 1986. If you are interested, please contact Gregory Griffin,
Department of Communication (D-003), University of California, San Diego,
La Jolla, CA 92093, or call (619) 452-2379 for an application. Three
letter of recommendation will be required as well as Graduate Record
Examination scores.

Here's some info on publications concerning PLATO's authoring language (I hate
that term). Hope it's some help. -Brod
. . .
PLATO Author Language Reference Manual
This manual describes the PLATO author language and is
intended as a detailed reference source. It is designed
as a reference for the experienced author who is familar
with the fundamentals of the CDC PLATO author language.
publication number: 97405100
PLATO Author Language Instruction Formats
This pocket-sized manual provides PLATO authors with a
complete summary of author language instruction formats,
keyboard formats, and a summary of Author Mode page
options.
publication number: 97406600

"CommonLoops"
Gregor Kiczales
Xerox Palo Alto Research Center
CommonLoops is a merger of Object Oriented Programming and Lisp. It
has a unique combination of features:
1) No special syntax: Most attempts to add object-oriented programming
to Lisp have resulted in special syntax for message sending. In
CommonLoops, there is no syntactic difference between calling a function
and "invoking a method."
2) Method Specification: In object oriented programming, methods are
specified in terms of the class of the object being sent the message.
One can think of this as specifying the type of one argument of the
method. In CommonLoops, one can specify the type of any number of
arguments to a method.
3) Type space: The "object" space is an extension of the normal Lisp
type space, not a separate space as in Loops or Flavors.
4) Metaclasses: The implementation of a type (determined by the
"metaclass") is independent of the type description. This allows
tradeoffs between early binding and ease of exploratory programming.

Recovering Surface Shape
from an
Extended Gaussian Image
James J. Little
Artificial Intelligence Laboratory
The Extended Gaussian Image (EGI) of an object records the variation
of surface area with surface orientation. When the object is polyhedral,
the EGI takes the form of a set of vectors, one for each face, parallel
to the outer surface normal of the face. The length of each vector is the
area of the corresponding face.
The EGI uniquely represents convex objects and is easily derived from
conventional models of an object. The EGI of a sensed object can be computed
directly from photometric stereo, or by differentiating depth maps from
binocular stereo or laser ranging. It can be used both in recognition tasks
and in determining the attitude of objects.
Here the representational power of the EGI is explored.
There are two aspects to describing shape for polyhedral objects: first, the
way in which faces intersect, termed the adjacency structure, and, second,
the location of the faces in space. The adjacency structure describes
the combinatorial properties of the object. An iterative algorithm is
described which converts an EGI of a polyhedron into an object model in terms
of coordinates of vertices, edges, and faces. The algorithm converges to
a solution by constrained optimization.

"MED2: An Expert System Shell for Diagnosis and Therapy in Complex Domains"
Frank Puppe
Kaiserlautern University
Germany
Concentrating on the medical domain, MED2 is a shell combining a wide
variety of important aspects of clinical reasoning. It's
"Working-Memory" control structure involves investigating a set of
hypotheses simultaneously, avoiding the shortcomings of focussing on
the top-hypothesis only. This concept allows using differential
diagnosis techniques and exploiting relationships among patho-concepts
in an efficient manner. Other interesting features of MED2 include
separation of database and diagnostic reasoning, temporal reasoning,
and belief revision.

Dr. Michael R. Raugh
Research Institute for Advanced Computer Science

An exciting new concept in which information is stored in a large number
of neighboring addresses determined by "content," produces a memory
that retrieves causal relationships as well as sequences of episodes and
is sensitive to similarity. It is also forgetful and reinforcable: a
memory much like yours and mine.
