Abstract: Unification-based grammar formalisms typically use attribute-
value matrices as repositories of information derived from
utterances. In previous work we have shown how to represent
grammatical specifications as logical formulas which speak directly
about these matrices. This involved the use of a particularly
simple form of deterministic propositional dynamic logic. In this talk,
we will review this logic, and then discuss how to extend the
logic to speak about set-valued matrices, which involves
a notion of nondeterminism.
Examples will be given involving modeling common knowledge
as a certain non-wellfounded set (its elements include the set itself),
and some coordination phenomena in lexical-functional grammar.
Each example illustrates a particular kind of logical expression.

Recursion theory provides a relatively abstract,
elegant account of the absolute boundaries of computability
by discrete machines. The insights it can provide are best
described as philosophical. In this talk I examine a sub-
part of this theory pertaining to machine learning, specifi-
cally, in this case, language learning.
I will describe Gold's influential, recursion
theoretic, language-learning paradigm (and variations on the
theme), point out its easily seen, considerable weaknesses,
but then argue, by means of example theorems, that it is
possible, nonetheless, to obtain some insights into language
learning within the general context of this paradigm.
For example, I will squeeze some insight out of a
theorem to the effect that allowing a kind of vacillation in
the convergent behavior of algorithmic, language-learning
devices leads, perhaps unexpectedly, to greater learning
power.
I'll sketch the proofs of a couple of the theorems, in
part to convince you they are true, but mostly because the
proofs are beautiful and illustrative of techniques in the
area.

Intelligent, Communicating Agents
Nils J. Nilsson
(nilsson@score.stanford.edu)
Department of Computer Science
Stanford University
February 18
Research in artificial intelligence (AI) has concentrated largely on
systems that are able to reason about specialized topics. Typical
examples are expert systems. Except for work in robotics, AI
researchers have not yet paid much attention to connecting their
reasoning systems to the physical world, and robotics work to date has
not focused on high-level reasoning. We examine the special problems
encountered when the computational chain from sensory perception to
effector action is forced to go through a reasoning system (as it
sometimes must if the system is to perform appropriately in complex
environments). We are concerned especially with designing intelligent
systems that must function in environments in which there are other
active entities---entities complex enough that it is best to consider
them as "agents" having beliefs, goals, and intentions. A central
problem in such research concerns the communicative acts engaged in by
such agents.
There will be a series of three lectures. The first, by Nilsson,
will give an overview of the ICA project and will discuss some of the
approaches being taken in designing the overall architecture of these
agents.

NEW LECTURE NOTES
Two new titles in the CSLI Lecture Notes series have recently been
published. The first, by David Hilbert, is entitled "Color and Color
Perception: A Study in Anthropocentric Realism." A brief description
of the book appears below. "Natural Language Processing in the 1980s:
A Bibliography" (ed. Gerald Gazdar et al.) is the second volume.
This book contains over 1,700 entries and an introduction, as well as
two indexes, one to keywords, the other to second and subsequent
authors. An online version of this bibliography can be found on
Russell, and, according to Jeff Goldberg, "It is possible to search
this bibliography automatically by computer mail." As he points out,
"Mail to clbib@russell.stanford.edu with the word `help' as the
Subject line of your message for details. Most questions you may have
are likely to be answered in that file. Mail to
clbib-request@russell.stanford.edu
to report bugs in the program that handles the automatic searching."
Both titles are distributed by the University of Chicago Press and
may be ordered directly (5801 Ellis Avenue, Chicago, Illinois 60637)
or purchased at the Stanford University Bookstore.

ISBN 0--937073--28--8 (Paper) $11.95
ISBN 0--937073--26--1 (Cloth) $29.95
Color and Color Perception
Color has often been supposed to be a subjective property, a property
to be analyzed correctly in terms of the phenomenological aspects of
human experience. In contrast with subjectivism, an objectivist
analysis of color takes color to be a property objects possess in
themselves, independently of the character of human perceptual
experience. David Hilbert defends a form of objectivism that
identifies color with a physical property of surfaces---their spectral
reflectance.
This analysis of color is shown to provide a more adequate account
of the features of human color vision than its subjectivist rivals.
The author's account of color also recognizes that the human
perceptual system provides a limited and idiosyncratic picture of the
world. These limitations are shown to be consistent with a realist
account of color and to provide the necessary tools for giving an
analysis of common-sense knowledge of color phenomena.

PARSING SEMINAR
Why can't I spread peanut butter AT the wall?
Michael Brent
This talk provides an introduction to the problem of preposition
selection. One part of the problem is knowing that, while you can
spray water AT something, you can't spread peanut butter AT something.
Another part of the problem is knowing that John sprayed paint ON the
wall implies that John sprayed paint AT the wall, but not vice-versa.
This talk presents a theory in which both types of facts are derived
from a single meaning representation. Next, a program that directly
implements the theory is presented, and the significance of
implementing linguistic theories is addressed. Hopefully, a
demonstration of the program will be available. Finally, the use of
this sort of knowledge in a lexicon for automated language processing
and reasoning are briefly addressed.

CALL FOR PAPERS AND REFEREES
HAWAII INTERNATIONAL CONFERENCE ON SYSTEM SCIENCES - 22
SOFTWARE ENGINEERING PROCESSES: MODELS AND ANALYSIS
KAILUA-KONA, HAWAII - JANUARY 3-6, 1989
The Software Track of HICSS-22 will contain a special set of papers focusing
on a broad selection of topics in the area of Software Engineering
Processes: Models and Analysis. Software engineering process modeling is
defined as a means of representing, analyzing, and predicting the effects of
changes on software development and related processes.
The need to model and analyze the software development process is more
important today than ever, because the advent of new technologies aimed at
various aspects of that process is forcing managers and developers to decide
how to best utilize these technologies. Until recently, those decisions
have been made primarily by intuition, with little empirical data
to substantiate promises of productivity and product quality gains. Process
modeling and analysis can increase our knowledge of the software engineering
process, and, therefore, support the improvement of software engineering
practices by:
Enabling effective communications regarding the process
Facilitating reuse of the process
Supporting evolution of the process
Proposing alternative processes tailored for software development paradigms
Facilitating management of the process
The presentations will provide a forum to discuss new advances in theory and
applications adressing the functional, behavioral, organizational and data
aspects of a process in addition to work in the area of process simulation
and automated process analysis. Papers are invited that may be
theoretical, conceptual, tutorial or descriptive in nature. Those papers
selected for presentation will appear in the Conference Proceedings
which is published by the Computer Society of the IEEE. HICSS-22 is
sponsored by the University of Hawaii in cooperation with the ACM, the
Computer Society, and the Pacific Research Institute for Information Systems
and Management (PRIISM). Submissions are solicited addressing the
following topics:
What are the requirements for process representation formalisms?
What environments (programming languages, systems analysis tools, expert
systems, etc.) are supportive of these formalisms?
How can influences on a process, such as employee motivation, be
modeled and how can these influences be measured?
What must be measured to provide a predictive capability in models?
What parameters are required to validate experiments and substantiate
results?
How can the effect of technology transition be measured and anticipated?
What is a "good" process; can process quality be measured?
Can modeling determine the quality of a process?
What progress is being made in the construction and validation of software
engineering process models and in the quantitative analysis of software
engineering processes?

________________________________________________________________________
Tutorial IV - Wednesday Morning, April 27, 9:00 am - 12:30 pm
Acquisition of Knowledge from Data
Instructor: Prof. Gio Wiederhold, Stanford University, Stanford,
California
Dr. Gio Wiederhold is Associate Professor of Medicine and Computer
Science (Research) at Stanford University. His research involves
knowledge-based approaches to medicine, design, and planning. He is
the Editor-in-Chief of ACM's Transactions on Database Systems and
associate editor of M.D. Computing and IEEE Expert magazine.
Wiederhold has over 130 publications, including a widely used textbook
on Database Design. In 1987, McGraw-Hill published his new book, File
Organization for Database Design.
Course Description: The architecture of an operational system, RX, is
presented which uses knowledge-based techniques to extract new
knowledge from a large clinical database. RX exploits both
frame-based knowledge and rules, as well as a database. Frames are
used to store deep and interconnected knowledge about disease states
and medical actions. Definitional and causal knowledge is
represented by inter-connections between frames that go across the
hierarchies, sideways as well as up and down, so that the aggregate
knowledge is represented by a network. Rules select the appropriate
statistical methods used to reduce the volume of data into
information. The database contains observations on rheumatic
diseases, collected over a dozen years.
