The BEES project:
Better Explanations for Expert Systems.
The aim of the BEES project is to improve the communication and
cooperation between users and knowledge based systems. It resulted
from the realization that current expert systems (ES) provide very
limited explanations to their users (the traditional "how" and "why"
questions). In many cases their acceptability, marketability and
usability would be greatly improved if such systems could interact in
a more cooperative way to solve problems through the combined
expertise of user and ES.
Development of more cooperative ESs involves investigation of what
domain knowledge is needed and how it should be represented so that
the ES can answer some of the many different sorts of questions which
users wish to ask. Additionally, the ES must hold information about
the user, so that it can communicate effectively and efficiently, in
terms which the user understands.
We are currently working on the following areas: representing the
variety of knowledge required, natural language processing, generating
textual responses, integrating graphical and textual explanations,
behavioural studies of advisors and users, developing a taxonomy of
explanations.

Subject: Workshop Announcement & Call for papers
CALL FOR PAPERS
FIRST ANNUAL SNePS WORKSHOP
Co-Sponsored by the SNePS Research Group and the
SUNY at Buffalo Center for Cognitive Science
November 13, 1989
280 Park Hall
North Campus
SUNY at Buffalo
SNePS, in its various incarnations, is being actively used and
developed at various AI research labs around the world. The
aim of this workshop is to try to get together researchers who
are (have been, or are considering) using SNePS as a research
tool for AI modeling as well as those who are (have been,
or are considering) evaluating SNePS as an AI research
environment.
The theme of this workshop is to present a survey of
current and on-going research and developments at various
research sites. Attendance at the workshop
will be kept small (by invitation only) to allow for maximum
possible interaction among participants.
The workshop will be semi-formal and held on the
campus of SUNY at Buffalo (where the SNePS headquarters are
located). All papers presented will be
edited and compiled into Proceedings which will be
published as a Department of Computer Science, SUNY at
Buffalo Technical Report.
To be invited to the workshop, you have to do one of the
following (preferably by e-mail):
1. Submit a one page abstract of a paper to be considered
for presentation.
2. Submit a short write-up of your current research and how
it does/might relate to the SNePS family of projects.
We will also schedule a time slot for live demonstrations of systems.
Those interested in giving demonstrations should submit a small
description outlining the nature of the demonstration along with
hardware/software/time requirements.
DEADLINES
Abstracts/Research Summaries due on Friday, October 6, 1989.
Notification of acceptance/participation by October 13, 1989.
Final papers due on Tuesday, October 31, 1989.

The conventional artificial intelligence approaches are not viable when
large text samples in arbitrary subject areas must be processed. Text
analysis methods based largely on statistical methods have, however,
been used successfully in information retrieval and related areas for many
years.
The main text analysis methods usable with general purpose texts are
briefly reviewed and applications are described in such areas as
document retrieval, book indexing, linking of related text excerpts, subject
area organization, and so on. Evaluation output is shown wherever
possible to demonstrate the effectiveness of the proposed methodologies.

Subject: Re: Connectionist Approaches to NLU
Date: 14 Sep 89 00:20:31 GMT
Last week I sent a request for references on connectionist
approaches to natural language processing. Special thanks to:
Ron Chrisley of Xerox
Trent Lange of AI Labs, UCLA
Diana Roberts of HP Labs
Here are some of the references they suggested, plus a few
I found myself. Note that I also included approximate location
of the authors. I'll be grateful if you could still contribute to
this list and send me some additional information on yours or
your colleagues' work in this area. Again I will summarize the
responses to the net.

What KL-ONE Lookalikes Need
to Cope with Natural Language

One of the major drawbacks of current NL processing systems is an
adequate representation of and reasoning about plurals. This is true
because current knowledge representation languages do not provide well
suited representational means neither to describe sets, subsets, and
elements nor to deal with the respective relations or use them in
specially tailored inference systems.
On the other side, there exists (at least) one linguistic theory about
plurality in natural language, the General Quantifier Theory (GQT).
What we want to present in this paper is how we adopted this theory
into the already existing framework of the XTRA system. Our goal
therefor is to develop a well-grounded knowledge representation
formalism able to represent sets as well as to deal with them and
combine this representation formalism with a well-defined linguistic
theory.
The knowledge representation language SB-ONE+ integrates sets into the
KL-ONE like KR language SB-ONE. It realizes this by means of
regarding sets as epistemological primitives, thus allowing for both
an implementation of set-relevant properties (like reasoning about
subset-of and element-of relationships) in the system as well as a
description of sets as elements inside the TBox if relevant for the
domain under consideration. Taking SB-ONE+ as representational basis,
we show how some inte- resting results from GQT are implemented in the
XTRA system.
