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

			       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.

   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?

Conference Organization and Fee Structure
_________________________________________

The three day EDS Conference is organized into the Technical Program
and a concurrent Tutorial Program.  There are separate fees for each,
and a special Conference/Tutorial Package fee is also available.

The Conference Fee includes the Technical Program consisting of the
Keynote Address, Paper Sessions with twenty-seven high-quality papers,
three Panels, Proceedings, Exhibits and Vendor Presentations, three
Luncheons, Coffee Breaks, a Hospitality Hour and our Theme Party,
Campaign Capers.  The Spirit of Washington Cruise is an optional
social event.  Space is limited for the cruise, and early registration
is required.

The Tutorial Program consists of four half-day tutorials, running
concurrently with the Technical Program.  It is designed to provide
participants with the latest concepts, tools and techniques related to
R&D in Expert Database Systems.  You may enroll for up to four
tutorials.  Each tutorial includes tutorial notes, a coffee break and
a luncheon.  Thus, participants may choose to attend only tutorials
without attending the Conference.  Tutorial participants may purchase
Social Function tickets separately.

The Conference/Tutorial Package is designed to allow conference
participants to attend tutorials at reduced rates, enabling
participants to concentrate on special interest areas of EDS.

Tutorial Program
=========================

Tutorial I - Monday Afternoon, April 25, 1:30 pm - 5:00 pm

Logic and Databases
Instructor:  Dr. Carlo Zaniolo, MCC, Austin, Texas

Dr. Zaniolo heads a group at MCC performing research on deductive
databases and logic programming.  He has held positions at Sperry
Research and Bell Laboratories.  He is the author of over 40 technical
papers, a member of numerous Program Committees, and edited the
December 1987 Data Engineering special issue on Databases and Logic.

Course Description:  There is a growing demand for supporting
knowledge-based applications by means of Knowledge Management Systems;
these will have to combine the inference mechanisms of Logic with the
efficient and secure management of data provided by Database
Management Systems(DBMS).  The major topics are:  Logic and relational
query languages; Semantics of Horn Clauses; Prolog and DBMSs; Coupling

Tutorial II - Tuesday Morning, April 26, 8:30 am - 12:00 am

Distributed Problem Solving in Knowledge/Data Environments
Instructor:  Prof. Victor Lesser, University of Massachusetts,
Amherst, MA

Dr. Lesser is Professor of Computer and Information Science at UMASS,
where he heads research groups in Distributed Artificial Intelligence
and Intelligent User Interfaces.  Prior to joining UMASS in 1977, he
was on the faculty of Carnegie-Mellon University, where he was a
Principal in the development of the HEARSAY Speech Understanding
System and responsible for the system architecture.

Course Description:  This tutorial will explore the major concepts and
systems for cooperative knowledge-based problem solving.  The major
topics include:  Connectionist, Actor and Cooperating ES paradigms;
Conceptual Issues including:  examples of distributed search,
interpretation, planning and cooperation, global coherence, dealing
with inconsistency and incompleteness, sharing world views, and design
rules for a cooperating ES; System Architectures for satisficing,
negotiation, tolerance of inconsistency in problem-solving,
organizational structuring, integration of local and network control,
and expectation-driven communication; Discussion of working systems
including Contract Nets, Partial Global Planning, AGORA MACE, ABE,
DPS, and MINDS; and Future Directions.

Tutorial III - Tuesday Afternoon, April 26, 1:30 pm - 5:00 pm

Knowledge Representation and Data Semantics
Instructor:  Prof. John Mylopoulos, University of Toronto, Canada

Dr. John Mylopoulos is Professor of Computer Science at the University
of Toronto and research fellow of the Canadian Institute for Advanced
Research. His research interests include knowledge representation and
its applications to Databases and Software Engineering.  Dr.
Mylopoulos has edited three books on the general topic of AI and
Databases. He received his Ph.D degree from Princeton University.

Course Description:  Knowledge Representation including history, basic
paradigms such as semantic nets, logic-based representations,
productions, frames, role of uncertainty, and inference mechanisms,
examples such as KL-ONE and OMEGA; Semantic Data Models including
historical models such as Abrial's Binary Model, Entity/Relationship,
RM/T and SDM, detailed study of ADAPLEX, TAXIS, and GALILEO,
implementation techniques; Comparison of SDMs to Object-Oriented model
such as POSTGRES and GEM as well as Deductive Databases.

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.
