CALL FOR PARTICIPATION
IJCAI-91 Workshop on
OBJECTS AND AI
Sunday, August 25, 1991
Sydney, Australia
Recently, object-oriented programming has gained tremendous
recognition as a powerful paradigm for structuring and programming
complex systems. At the same time, AI researchers are still striving
for new representational and software engineering advances for
developing complex AI applications. Cooperation between Objects and AI
can be an important step toward achieving advances in both fields.
This workshop will provide a forum for researchers in AI and OOP to
exchange ideas and discuss issues related to the two fields and the
potential cooperation between them. The focus of the presentations and
discussions will be on both the theoretical foundations and practical
applications and implementations of object-oriented programming in AI.
Tentatively, the workshop will be divided into four main sessions,
each moderated by one of the workshop organizers.
1) Objects and AI: Concepts and potential cooperation.
2) Object-oriented knowledge representations: Theory, formalisms and
practical issues.
3) Object-oriented environments and architectures for AI.
4) Object-oriented AI applications.
In the first session, participants will discuss how they view objects,
and identify their impact on AI. For example, objects may be viewed as
modules of knowledge or activities--agents. From this view, the
discussion should focus on identifying how these agents can contribute
to advances in AI research. From a different perspective, concepts and
methodologies of programming with objects that are applicable, and
could potentially contribute, to AI may be addressed and debated as
part of this session. This discussion should also identify those
concepts that are fundamentally different and may cause problems if
the two areas are combined. Examples for such discussion are objects
vs. frames, AI classification vs. class inheritance hierarchies, and
the suitability of object-oriented methodologies in dealing with ill-
defined domains.
The second session will focus on issues related to knowledge
representation using objects. Participants should discuss the
advantages and/or limitations of concepts such as encapsulation and
information hiding when applied to knowledge representation. Also,
objects have often been criticized for lacking formalisms and
semantics for object-oriented knowledge representation. The
discussions in this session should address these theoretical issues
and identify the potential problems associated with such lack of
formalisms.
The third session is intended to explore existing and future object-
oriented architectures as they may apply to the development of AI
tasks. The discussion should identify the advantages and disadvantages
of using class-based vs. delegation-based systems, concurrent and
distributed object-oriented architectures, communicating and
intelligent agents, reflective systems, and integrated programming
environments.
The last session will be devoted to presentations and discussions of
object-oriented AI applications. Discussions should focus on and
emphasize the aspects of OOP that contribute to the success of these
systems. Examples of such systems are object-oriented expert system
shells, natural language processing systems, learning systems,
simulation, scheduling and planning systems, and constraint
satisfaction systems.
Workshop attendance will be by invitation only and is limited to 30
participants. Invitations will be issued on the basis of extended
abstracts or position papers. Appropriate papers should not be less
than 3 single spaced pages and should state clearly their authors'
position and supporting arguments for issues relevant to the workshop
theme. Relevant topics include (but are not limited to):
o Formalisms and semantics for object-oriented knowledge
representations.
o Object-oriented methodologies for handling ill-defined domains.
o Object class hierarchies vs. AI classification hierarchies.
o Objects vs. frames: similarities and differences.
o Objects in distributed AI.
o Intelligent and communicating agents.
o Reflective object-oriented languages for AI development.
o Pattern matching with objects: problems and solutions
o object-oriented tools for designing and developing AI systems.
o Object-oriented protocols for AI tasks.
o Integration of object-oriented and AI programming paradigms.
The papers will be reviewed by members of the workshop committee and
acceptance will be based on both the relevance of the work to the
workshop theme and the quality and clarity of the papers. Accepted
papers will be distributed to the participants at the workshop, and
based on the workshop outcome, we may elect to generate some form of
formal publication that will include longer versions of the
accepted submissions.
IJCAI policy this year requires successful workshop applicants to
register for both the conference and the workshop. Workshop
registration fee is $US65.00.

SYMPOSIUM ON
ARTIFICIAL INTELLIGENCE, REASONING AND CREATIVITY
20-23 AUGUST 1991
immediately preceding the
International Joint Conference on Artificial Intelligence
(IJCAI'91)
organised by
GRIFFITH UNIVERSITY, BRISBANE, AUSTRALIA
to be held at
LAMINGTON NATIONAL PARK, QUEENSLAND, AUSTRALIA
AIM
Creativity is one of the least understood aspects of intelligence. It is
commonly regarded as 'intuitive' and not susceptible to rational enquiry.
However, there is now considerable work in artificial intelligence and
cognitive science which addresses creativity. This symposium will provide a
forum for exploring and discussing these ideas, and for suggesting directions
for future research. It aims to attract practitioners of both 'cognitive'
and 'technological' artificial intelligence.
KEYNOTE SPEAKER - PROFESSOR MARGARET BODEN
Margaret Boden, in her talk on `Creativity and Computers', will discuss
how computational concepts drawn from artificial intelligence can explore
creativity. Computers can sometimes do apparently creative things;
more to the point, they can suggest how we manage to do so. Computational
ideas are therefore helping us to understand how human originality is
possible.
Margaret Boden is Professor of Philosophy and Psychology, and Founding
Dean of the School of Cognitive Sciences, at the University of Sussex, UK. Her
recent publications include `Artificial Intelligence and Natural Man' (1987),
`Artificial Intelligence in Psychology' (1989) and `The Creative Mind: Myths
and Mechanisms (1991).
INVITED SPEAKERS include
Ernest Edmonds, Loughborough University of Technology, UK
John Gero, University of Sydney, Australia
Graham Priest, University of Queensland, Australia
Roger Wales, University of Melbourne, Australia
TOPICS FOR PRESENTATION AND DISCUSSION
The symposium calls for extended abstracts of 750-1,000 words. The following
are suggested areas only:
- Models of creativity
- Modelling creative processes
- Creative reasoning, e.g theory generation in science
- Analogical reasoning
- Case-based reasoning
- Nonmonotonic reasoning
- Thought experiments
All abstracts will be refereed. Accepted papers will be subjected to a
further refereeing process for publication by Kluwer Academic Press.
The symposium will be structured to provide adequate time for both
presentation and discussion.
SUBMISSION
Three copies of extended abstracts are required by 31 May 1991.
Abstracts may be submitted electronically as LaTeX or plain ASCII files via
email but hard copies must also be submitted. Two hard copies of final
versions of accepted papers, and an electronic version on Macintosh
disk or via email are required at the time of registration on 20 August
1991. Authors of accepted papers will be expected to sign a copyright
release form to allow publication of the proceedings. At least one
author of each paper is expected to present the paper at the symposium.
PREPRINTS AND PROCEEDINGS
Accepted extended abstracts will be printed in the form of Preprints
and be available for distribution at the time of registration.
Full papers will be published subsequently by Kluwer Academic Press.
LOCATION
The symposium is being held at O'Reillys Lodge in Lamington National Park,
Queensland - a rainforest 120 km south of Brisbane. Rainforests vary from the
temperate beech forest of the higher altitudes to the warm subtropical
rainforest of the valleys. There is an abundance of rare and spectacular
plants (orchids, ferns, giant epiphytes, mosses, luminous fungi) and a diverse
community of birds and animals (crimson rosellas, king parrots, bower birds,
miniature kangaroos, brush turkeys) all coexisting beneath the lofty
rainforest canopy. On the final day of the symposium there will be ample time
for guided or independent bush walks, 4WD bus trips, barbeques and evening
entertainment.

The Biological Knowledge Laboratory is a basic research
and development group. Its goal is to develop techniques to
automatically capture knowledge from the full text and
diagrams in biological research articles and make it
available to research scientists and students. The research
includes computational linguistics, computer vision,
knowledge representation and reasoning and human-computer
interaction. The Lab is supported by a major four-year grant
from the National Science Foundation. The Lab tours include
presentations and computer demonstrations.

or call the lab at 617-437-2076.
Abstract for seminar on April 17:
The Biological Knowledge Laboratory is dedicated to the
development of techniques and computer systems for dealing
with scientific knowledge. This talk, intended for a general
audience, will review the Lab's progress in the first two
years, including: The application field of bacterial
chemotaxis; the encoding/entry of a large corpus of research
articles; lexicon development and attempts to parse the full
text of the articles; image analysis and computer vision
techniques for analyzing the diagrams in the articles. We
also describe our first steps towards knowledge
representation and the development of an intelligent
interactive system called the Scientist's Assistant. We
point out some of the interesting issues that arise when one
attempts to represent the leading edge of scientific
knowledge in the computer because such knowledge is often
tentative and incomplete and must be revised as time passes.
Abstract for seminar on April 18:
In order to build a Scientist's Assistant that will allow
conceptual retrieval of scientific knowledge from a large
knowledge base, it is necessary to analyze and index
knowledge of the full text and graphics of research papers.
This talk discusses our recent work on this topic, covering
both conceptual and implementation issues. We first
describe the coupling of syntax and semantics embodied in
the Montague approach to semantics. We explain how it is
implemented in the Alvey Natural Language Parser that we
use. We then describe a novel use of the Alvey parser and
its semantics to generate a token stream translator that
builds structures for specialized scientific text entities
such as numbers in scientific notation, bibliographic
references and the like.
The bulk of the talk is given over to diagram
understanding, which is far less developed than natural
language understanding, but no less important in scientific
document analysis. In our approach diagrams are modeled by a
collection of constituent productions with accompanying
constraints. Many of the constraints involve Generalized
Equivalence Relations (GERs) which are analogous to
unification constraints in modern grammars. The
implementation of this approach is aided by the GOSSAMER
spatially associative data structure for graphic objects
which allows efficient implementation of the GERs.

"CONCEPTUAL INFORMATION EXTRACTION AND RETRIEVAL"
Abstract
In this talk, I will cover three interacting areas of active research
here at GE R&D. First, I will give the history and status of
our work in the area of data extraction---extracting fixed-field
information from free-form text in constrained domains. Our
approach to natural language data extraction centers on a custom
lexicon design, innovative methods of parser control, and
integrating strategies for language analysis---statistical, syntactic,
semantic, phrasal and domain-driven.
Second, I will describe the uses we have put our natural language
processing software to in improving traditional keyword-based
information retrieval applications. Our primary methods have been
to disambiguate keywords by the use of separate text database
segments, and to extract conceptual relationships in addition to
simple words meant to represent concepts.
Finally, I will give an overview of a conceptual information retrieval
mechanism that has the properties of a distributed representation,
but is implemented with a localist representation system. In particular,
this method of retrieval uses a modified form of spreading activation
and intersection search to support (1) contents addressability, (2) partial
and incorrect matching and (3) automatic analysis of the similarities
and differences between the input query and the retrieved representations.
