Subject: Parallel LISP Environments
We are planning to implement a parallel-environment
simulator in LISP for trying out various control
metaphors that require parallelism.
Anyone already having any implementations or
experiences in using such environments?
We would appreciate any kind of responses that could
help in highlighting various aspects of design as well
as implementation.
Thanx.
Deepak.

Subject: Simulators for hypercube architectures
Lisa Sokol (sokol@mitre) and I are investigating the use of parallel
architectures for object-oriented simulations. We have a large simulation
called the BEM (Battlefield Environment Model) which is written in the
simulation language ROSS, which runs on top of Franz LISP on a VAX. We
would like to have a hypercube simulator which would help us investigate
strategies for distributing objects in a hypercube. Our main problem seems
to be the integration of LISP code with the simulators. Translating the
Lisp into C would be messy at best, even with a translator program. Another
possibility would be to have Franz LISP running in another process on the
VAX and communicating with the simulator process. That sounds pretty messy
also, particularly for analyzing the timing since the Lisp is running
outside of the simulator process. For our purposes, it may be better to
write a Lisp simulator of a hypercube architecture. Do you know of anyone
who already has such a simulator? We expect that Lisp will be available on
some hypercube in the next year, and our simulator studies should allow us
to determine how to distribute the objects by that time.

Subject: texture images
I am collecting a set of digital images of natural textures. If you
have any such images, I would appreciate your help. They could either
be images of single textures (Brodatz-type) or images of natural
scenes constaining several textured surfaces. I will make the
collection available to the AI community.

Subject: Tax Expertise Available for Expert System
Prof. Lewis Solomon is a specialist in tax law and is interested in
working with someone on an expert system in that domain. He would also
like to hear about existing systems. His US Mail address is:

Subject: Intelligence as the ability to apply the distributive property
To wax philosophical for a while and then get down to specifics:
1. A major (the major?) aspect of intelligence is the ability to
see several instances of a thing and then be able to abstract
out common features. This is terribly handy for information
representation as it allows one to condense, by "factoring out",
the total info. Nothing really new here - the notion of
"inheritance", based on the is-a relation is a clear example.
2. The whole problem of context seems strongly related - isn't
context simply that which we hold constant over time, until we
are forced to assume something new? - finding the antecedent
of pronouns can be seen as the problem of: given the most
recent n sentences, what (single, common) interpretation allows
me to maximize the number of unchanged assumptions?
3. A big issue then becomes, how rich is the repertoire of
pattern-matching mechanisms? Put concretely, and blithely
assuming that you can represent anything with lists, given n
lists (Lisp-type if you like), which abstractions are available
for describing (by generalizing about) them, and which of several
applicable abstractions should take precedence? For example,
is there a Lisp system out there which would abstract over the
following sets of lists the way I suspect would be done by thee
or me? Any research being done on general-purpose similarity
finding among Lisp lists?
(a b c), (a b c), (a b c)
(a b c), (a b w), (a b q), (a b d e r)
(a b c q), (a b c e), (a b c (d e (w e)))
(a b c), ((a) (b) (c)), (((a)) b c)
(a b c), (aaaa bb ccccc), (aaa b cccc)
(a b c), (A B C), (a B c)
((a b c) (b)), ((a b c d e f) (b c d e)), ((a b (c d) (e f)) (b (c d)))
(a a a), (b b b b b b), (xx xx xx xx)
(2 3 5), (5 6 11), (12 2 14)
(2 3 5), (5 6 11), (12 2 14), (one three four), (3 four 7)
The last set is, of course, somewhat unfair, since it relies on
knowledge of English semantics, and not simply on structural
properties.

Subject: AI Mag article on KR
The current (Fall 85) issue of AI Magazine has an article by
Ron Brachman raising one of the issues (lack of definitional
information) that has been bothering me about AI knowledge bases. He
explains why these capabilities are necessary, and then shows that they
aren't possible in a KR system where prototype information can be
overridden, i.e., where nodes are treated as prototypes containing
default information.
[Among other points, Brachman shows that a frame/semantic net/
inheritance network/nonmonotonic representation seems to have the
following limitations: it cannot determine automatically where in
the network to place an ELEPHANT-WITH-THREE-LEGS (or similar composite)
node; it cannot infer that this is a subclass of elephants, or indeed
that it has anything to do with elephants; it cannot infer that instances
have three legs; and it cannot recognize a three-legged elephant as
an instance of this concept. My 5-year-old also enjoyed the riddles
about "What's big and gray, has a trunk, and lives in the trees?"
(Valid answers in Ron's strawman representation systems are "elephants",
"giraffes", and "ideas".) -- KIL]

Subject: Expert Systems In Psychiatry (Responses)
I would like to thank all of the people who responded to my recent
request. The following is a summary of the responses which I have
received (so far). I have passed this information to Dr. David Atcher
in our Med. School, and he may be following up on some of these leads.
