COMMONSENSE AND NONMONOTONIC REASONING SEMINAR
A Minimal Model Semantics with Default Priorities
Paul Morris
IntelliCorp
Monday, 6 February, 3:15pm
MJH 301
Existing default reasoning systems may be divided into minimality
based formalisms, such as circumscription, and those that depend on a
fixed point construction, like default logic. The fixed point schemes
have appeared to possess an advantage in allowing implicit
specification of arbitrary priorities among defaults. However, they
also have disadvantages, including a lack of cumulativity, and
difficulty in properly representing some situations where a mere
possibility of some contingency is sufficient to overcome a default.
We present a model minimization scheme that supports implicit
specification of priorities among defaults. The system enjoys
cumulativity (like other model preference systems), and gives more
satisfactory results in situations where a possibility overcomes a
default.

SYMBOLIC SYSTEMS FORUM
The Ecology of Computation
Bernard A. Huberman
Dynamics of Computation Group, Xerox PARC
Friday, 10 February, 3:15
Room 60:61G
A most advanced instance of concurrent computation is provided by
distributed processing in open systems that have no global controls.
These emerging heterogeneous networks are becoming self-regulating
entities, which in their behavior are very different from their
individual components. Their ability to remotely spawn processes in
other computers and servers of the system offers the possibility of
having a community of computational agents that, in their
interactions, are reminiscent of biological and social organizations.
This talk will give a perspective on computational ecologies, and
describe a theory of their behavior, which explicitly takes into
account incomplete knowledge and delayed information on the part of
its agents. When processes can choose among many possible strategies
while collaborating in the solution of computational tasks, the
dynamics leads to asymptotic regimes characterized by fixed points,
oscillations, and chaos. We will also describe Spawn, an ongoing
project that utilizes idle computational resources in a distributed
network of high-performance workstations. Finally, we will discuss
the possible existence of a universal law regulating the way in which
the benefit of cooperation is manifested in the system.

UNISYS PAOLI RESEARCH CENTER
Pundit's First French Lesson:
The PRATTFALL Machine-Translation Module
Francois-Michel Lang
Unisys Paoli Research Center
(lang@prc.unisys.com)
This talk describes PRATTFALL (Pundit Reads And Translates Texts into
French, ALbeit Loosely), a machine-translation module built on top of
the PUNDIT natural-language text-understanding system. Both PRATTFALL
and PUNDIT are implemented entirely in Quintus Prolog; PRATTFALL is
based on Michael McCord's LMT system.
There are five principal components in PRATTFALL, each of which is
described in turn:
* Transfer from English to French
* Restructuring to conform to French syntax
* Assembling lexical items
* Inflection of lexical items
* Cleanup of inflected lexical items
The transfer component is implemented using a definite-clause grammar
modelled after one of the components of PUNDIT's SPQR module.
Familiarity with LMT, PUNDIT, and machine translation in general is
helpful, but not necessary.

Can't postnews, so trying this way.
Desperately looking for mail-addresses of people whose last names are:

all active in NLP research.
Sorry if this screws up something.

Does anyone out there have experience with, or references to, parsing
(ancient/koine) Greek text? I'm interested in developing tools for
detailed syntactical analysis of greek texts--any related information
would be welcomed.
Please mail to me...
