This is the second attempt at posting. The first one didn't seem
to make it onto the net. Apologies if you see this announcement
twice.
This is the follow up to the preliminary notice I posted to a
number of newsgroups several months ago. A number of people
responded then and this posting will be forwarded to them in
person. It has taken some time to select and organise the final
programme from submissions to EKAW91, hence the short notice given
here.
Even if the timing of this event means that you will not be able
to attend you might like to know that the Registration Form at the
end of this message contains check boxes to register your interest
for the Proceedings of the Fifth European Knowledge Acquisition
for Knowledge-Based Systems Workshop (EKAW91) [to be published by
Springer-Verlag in their Workshop in Computing Series] and/or next
year's event - EKAW92 to be held in Germany.
Please forward this posting to colleagues who may be involved in
the area of Knowledge Acquisition for Knowledge-Based Systems if
they are not regular readers of the 'net'.

Knowledge Acquisition for Knowledge-Based Systems
IEE/BCS Supported Colloquium
Monday, 20th May 1991, University of Strathclyde
Court/Senate Suite, Collins Building
Richmond St., Glasgow
INTRODUCTION
This colloquium is being held to coincide with the first day of
the Fifth European Knowledge Acquisition for Knowledge-Based
Systems Workshop (EKAW91). Leading practitioners in Knowledge
Acquisition and Machine Learning will be presenting the latest
developments in these fields. The presentations will be based on
the some of the best papers submitted for the EKAW91 event.
It is the objective of EKAW91 to assemble theoreticians and
practitioners of AI who recognise the need for developing methods
and systems to assist the process of acquiring and modelling
knowledge for knowledge-based systems. These techniques and
methods include, for example:
o Transfer/modelling of expertise-systems that obtain and
model knowledge from experts.
o Transfer/modelling of expertise-manual KA methods and
techniques.
o Apprenticeship, explanation-based, and other learning
systems; integration of such systems with other KA
techniques.
o Issues of cognitive psychology and expertise that
affect the KA process.
o Extracting and modelling knowledge from text.
o Integration of KA techniques within a single system;
integration of KA systems with other systems (hyper-
media, DBMS, simulators, spreadsheets...)
o KA methodology and training.
o Validation of KA techniques; the role of KA techniques
in validating KBS.
o Methods of capturing design knowledge and requirements.
o Theoretical framework for KA.
o Philosophical issues concerning knowledge and technol-
ogy.
o Results from Project SISYPHUS; the objective of the
project is to compare different methods and techniques
of KA. Two test bed domains have been chosen: 1. Text
Analysis, 2. Models of Problem Solving.

PROJECT SISYPHUS
At EKAW90 there was general agreement that a major focus of
knowledge acquisition research is the explicit representation of
problem-solving methods. As quite a few tools, techniques and
methodologies are currently being developed and used it would be
of great interest to create a situation where these different
approaches could be compared, contrasted and assessed. It was
decided to choose three or four task domains that introduce
considerable scope for knowledge acquisition. These task domains
would then provide a test bed for comparison of techniques.
It was proposed that researchers and practitioners (preferably
those belonging to a team or group) who were currently involved in
knowledge elicitation and acquisition analyze one sample problem
and make their analysis of this problem widely available. The
results of the analysis of each group (each using its own
approach) will be published in the proceedings of EKAW91 and will
be discussed during the workshop at special set sessions.
Of the task domains that were put forward for analysis, two
project champions (Dr Brian Woodward and Dr Marc Linster)
coordinated the efforts within their own domains of expertise; (1)
Text Analysis and (2) Models of Problem Solving, respectively.
(1) Text Analysis
Text-based material is a common source of information for
knowledge engineers when building knowledge-based systems. Text
may be generated from interviews, verbatim protocols and/or
textbooks and scientific or technical papers. Identifying
meaningful information and then developing useful knowledge
structures from text is the goal of text analysis for knowledge-
based development.
The call for submissions was directed to those researchers and
practitioners who have developed methods, techniques or tools for
text analysis. The goal was to identify and select
representative approaches to text analysis and then to offer the
same textual material for analysis.
The submission was to contain brief but clear statements about:
1. the underlying assumptions of the approach
2. the method for parsing text passages
3. the method(s) and underlying assumptions for analysis
of the parsed text
4. the knowledge representation formalism resulting from
the analysis
5. potential uses for the method to knowledge engineers
(2) Models of Problem Solving
Many research groups tackle the problem of explicit modelling of
problem-solving (see Karbach, Linster & Voss: "Models of Problem-
Solving: One Label - One Idea" in Proceedings of EKAW90). They
all use different examples to illustrate their work. We wanted to
encourage the members of the community to illustrate their
approaches using one test bed example selected from a set of
common examples that the organizers of Project SISYPHUS would
provide for the participants.
The problem to be modelled was to be a realistic synthesis type
problem. We were mainly interested in the explicit modelling of
problem solving methods. There was no implication that the
results must be or directly result in an operational knowledge
base. Mediating representations or specifications that were not
directly executable would be welcome.
The descriptions of the models would make the approaches
comparable and this comparison would hopefully help answer
questions such as:
1. How do the building blocks of each of the approaches
correspond?
2. Which problem-solving steps does an approach use and
are there common steps amongst the different
approaches?
3. What grain size is there?
4. Which part of the knowledge is generic to all task
domains?
5. What is task dependent in the approaches?
6. What is the role of the knowledge engineer?
The descriptions of the models would be the basis of the
discussion at EKAW91 and these discussions would hopefully result
in a common terminology as a first step towards a theory of
problem-solving in Knowledge-based Systems.
