Brief Description
The rule-based paradigm used in the building of many
Knowledge-Based systems implies that rule-based systems are
self-documenting and facilitate the addition of knowledge to the
knowledge-base in an ad-hoc manner (the No-Function-in-Structure
principle).Several first generation Knowledge-Based systems built
using this paradigm are being rebuilt because the maintenance
experience has shown that the paradigm is invalid .. The maintenance
of these systems became increasingly difficult to the point that an
expensive re-construction effort was seen as the only solution to the
burgeoning maintenance problem.Analysis of the maintenance problem
indicates that it falls in that class of problems usually associated
with information systems constructed with little, if any, application
of software engineering. Recent research has indicated that software
engineering has a major part to play in the design and construction of
Knowledge-Based systems, and that similar benefits gained from
applying software engineering to Information Systems would be
applicable to the organization. The application of software
engineering to Knowledge-Based systems facilitates the integration of
Knowledge-Based Systems with conventional Information Systems and the
systemUs maintainability.Research in this area should be directed to
such issues as: how much of software engineering is applicable to
Knowledge-Based Systems; what methodologies are needed; in what
fashion does the application of software engineering facilitate the
interfacing of knowledge acquisition to knowledge
representation/processing; how are accepted knowledge acquisition
strategies affected by the application of software engineering; how is
knowledge representation affected by software engineering; etc.This
workshop aims to bring together researchers involved with the software
engineering of Knowledge-Based systems. It is aimed at people working
with Knowledge-Based Systems having experience in: design
methodologies ; maintenance; structured knowledge acquisition;
knowledge representation; knowledge modelling. The workshop will run
for two consecutive days, with the first day consisting of keynote
presentations concluding with a panel session, open to the general
public, and the second day consisting of a set of presentations and
discussion, strictly limited to 20 people, on the basis of one author
per accepted submission over the two days. Each submission will be
refereed by the committee which will select the presentations for both
days. It is intended to publish the proceedings with each attendee on
the second day receiving a pre-published copy.Interested researchers
are invited to submit four copies of an extended abstract of no more
than two A4 pages. Paper copies only will be accepted.Late submissions
will be returned unopened

CALL FOR PAPERS
Natural Language Learning
August 25 1991 - IJCAI Workshop - Sydney
Machine Learning and Natural Language are two areas of Artificial
Intelligence which not only overlap with each other, but with other
significant areas of Artificial Intelligence and Cognitive Science.
The focus of this workshop is computational language learning
models. Primarily, we aim to bring together those who have
implemented language learning models, or aspects thereof. However,
we intend that computationally viable language learning theories
developed by Linguists and Psycholinguists will also be examined at
the workshop. In addition, Machine Learning or Natural Language
research which has not specifically been undertaken from a language
learning perspective may be considered relevant - in particular, for
example, work in Concept Learning and Semantic Representation.
Thus we wish to invite applications from all who have implemented
language learning programs, and we will further encourage
participation from those whose work could be of use in the
implementation of language learning systems.
A major goal will be the analysis of the various language
learning models to allow comparison and contrasting of the
theoretical perspective and hypotheses embodied, the implementation
techniques and learning algorithms, and the implications of the
virtues, failings and results of particular implementations and
modelling experiments.
Attendance will be by invitation, and the number of participants
will be strictly limited, probably to 35. It will be necessary to
charge a fee of $65 for each participant.
Issues
- -----
What technology and ideas can be imported into Natural Language
Learning from other areas of Artificial Intelligence and Cognitive
Science?
Which phenomena, hypotheses and theories have been modelled, tested
or used in Natural Language Learning, and with what success?
To what extent do results in Natural Language Learning suggest the
need for a revision of Formal Language, Linguistic, Neural Network
and Psycholinguistic theory and application?
How broadly must we define Natural Language Learning - in particular,
do we need to learn simultaneously interpretation of both the symbolic
and grounded modalities?
Possible Sessions
- ------- --------
The issues above suggest that the workshop could be organized into
sessions along the following lines:
Psycholinguistic Models
Learning Algorithms
Complexity & Restriction
Semantics & Representation
The final program will of course reflect the distribution of the
submissions received, and other issues may also be highlighted.

IJCAI-91 WORKSHOP ON THEORETICAL AND PRACTICAL DESIGN OF RATIONAL AGENTS
Sunday, August 25, 1991
Workshop Description
- -------------------
During the last few years, AI researchers have become increasingly
concerned with the problem of designing architectures for intelligent
systems that are required to operate in real-world environments. Based
on the sensory input from their environment, these systems must be able
to choose and execute appropriate courses of action to further their (or
their designer's) goals. Moreover, this must be done under possibly
stringent constraints on both time and information.
There has emerged a range of approaches to the design of such systems.
At one extreme are situated automata and related mechanisms, which
incorporate compiled or ``hard-wired'' capabilities to perform their
tasks. At the other extreme are situated planners or rational agents,
which perform much of their reasoning and planning in real time as
they interact with their environment.
This workshop will focus on the rational-agency approach to the design
of AI systems. Its purpose is to bring together researchers working
on various aspects of rational agency and on the design of systems
based on this approach. In the workshop, we will consider the
philosophical foundations and logical formalizations of rational
agency, the role of decision theory in deliberation and meta-level
reasoning, and the design and performance evaluation of such rational
agents in experimental and real-world domains.
Topics of Interest
- -----------------
Formalizations of Rational Agency
-- logics of beliefs, desires, and intentions
-- modelling quantitative aspects like probability, payoff, and utility
-- theories of belief, desire, and intention revision
Deliberation
-- role of decision-theoretic techniques
-- integration of decision-theoretic techniques with symbolic manipulation
of intentions
-- meta-level reasoning
Design and Evaluation of Rational Agents
-- architectural design of systems that incorporate one or more of the above
-- real-world and experimental applications of rational agency
-- evaluation criteria for rationality

Subject: IJCAI CFP: computational approaches to non-literal language
CALL FOR PAPERS
IJCAI-91 WORKSHOP
COMPUTATIONAL APPROACHES TO NON-LITERAL LANGUAGE:
METAPHOR, METONYMY, IDIOM, SPEECH ACTS, IMPLICATURE
Dan Fass, James Martin, Elizabeth Hinkelman
Sydney, Australia, 24th August 1991
1. Focus of the Workshop
The purpose of the workshop is to stimulate exchange and discussion of
theoretical issues and practical problems of artificial intelligence (AI)
models of non-literal language. Non-literal language includes metaphor,
idiom, "indirect" speech acts, implicature, hyperbole, metonymy, irony,
simile, sarcasm, and other devices whose meaning cannot be obtained by direct
composition of their constituent words. Non-literal language is increasingly
acknowledged as pervasive in natural language and is important to subfields of
natural language processing like machine translation and parsing ill-formed
input. Non-literal language has also attracted interest from researchers in
knowledge representation, planning and plan recognition, learning, belief
modeling, and other subfields of AI.
Researchers are invited to submit papers on topics including (but not limited
to) the computer recognition, interpretation, acquisition, generation, and
robust parsing of non-literal language. Issues of interest include:
o the relationship of non-literal to literal language,
o the adequacy of various forms of knowledge representation (symbolic vs
connectionist vs statistical),
o static vs dynamic mechanisms,
o general vs idiosyncratic treatment of instances,
o instances as novel vs conventional forms,
o comparison and contrast of models of the various forms of non-literal
language,
o broader implications for AI.

"The Linguistic DataBase (LDB)"
The LDB is a database system developed by the TOSCA group at Nijmegen
University which allows linguists who are not experts in computing
to access syntactically analyzed corpora. The data in the database
comprises `syntactic analysis trees' of the contiguous utterances
in a natural-language text. Since these trees are built from a
continuous text, they give a good representation of actual
language use and can thus provide a testing ground for linguistic
hypotheses. The range of extractable information in such a
database is mainly dependent on the degree to which the text has
been prepared. Formerly studies of corpora were restricted to the
level of words or word-classes, but with the Linguistic DataBase
it becomes possible to extend these studies to the level of
syntax, so that larger constituents can be analyzed.
Unlike currently available database packages, the LDB has
been created specifically to handle the type of data linguists
need to analyze - a labelled tree structure with a variable
number of branches at each node and the possibility of recursion.
The LDB can be used to examine the trees on the terminal
screen, search for utterances with given properties, and handle
database-wide queries about constructs in the utterances.
The LDB does not presume special graphics hardware. For
this reason it has been implemented for common machines (VAX and
IBM PC/AT) and common terminals (VT100, ADM3, etc.).
Where possible, special terminal features are used,
such as highlighting and graphics characters, but even on the so-
called `dumb' ADM3A the trees are represented by an
acceptable imitation of graphics. Terminal types not already
provided for can be easily installed by the user.
The LDB also does not presume a computationally expert
user. Thus control of the program is designed to be simple and
clear. The overall control is handled by a menu system, which
displays short descriptions of the choices, each of which can be
activated by a single keystroke. In the Tree Viewer, which is
used to examine an analysis tree on the terminal screen, there is
not enough space left on the screen to produce these
descriptions, so that commands (mostly of one keystroke) are
listed in abbreviated form. A description of all commands can be
accessed by a `help' command, however.
For queries going beyond a single tree, the Exploration Scheme
formalism has been developed. An Exploration Scheme consists of a
search pattern, itself a tree much like the analysis trees, and a
specification of the operations to be performed on the
information the pattern discovers. The possibilities of
Exploration Schemes are various. They range from a simple search
for a tree, in order to examine it with the Tree Viewer, to the
creation of frequency tables. The formalism is designed in such a
way that the novice can start exploring immediately. From there,
he can gradually expand his knowledge to the more complex
features. In order to facilitate formulating Exploration Schemes
the LDB has a special scheme editor.
The LDB package comes with the Nijmegen Corpus, a 130,000
word collection of modern British English with a full syntactic
analysis of each utterance. To each node in the tree (i.e. each
constituent in the utterance) has been attached a function and a
category label. In the future more corpora will become available.
Furthermore, since the database system is independent of both
formalism and language, it is possible to use it for any other
kind of analyzed corpus.
