Objective
of the workshop.
-
To bring together researchers and industrialists
in a less formal atmosphere whereby the issues associated with modelling,
discovering and maintaining the knowledge in a CBR system can be
discussed.
-
To provide a
means whereby new methods and tools for the definition, modelling,
and learning of knowledge for a CBR system can be put forward. This
includes methods and tools for case knowledge acquisition, knowledge
discovery from data, and CBR knowledge maintenance.
-
To stimulate discussion and the forging
of new ideas and approaches.
-
To help foster links between researchers
and between researchers and industry.
Topics
of interest for the workshop.
CBR
is regarded to be a more appealing approach to KBS development than
the traditional rule based approach mainly due to the more intuitive
nature of cases as a knowledge representation and reasoning formalism.
For a long time the case approach to KBS development was seen as a
possible solution to the knowledge acquisition and maintenance problems
associated with rule based systems. As the field of CBR has matured
support has grown for the view that CBR has not alleviated these problems
as hoped, but in many ways compounded them. It has become apparent
that as opposed to just the need to acquire domain (case) knowledge
there is also a need to acquire vocabulary knowledge, retrieval (similarity
/ indexing) knowledge, adaptation knowledge, and maintenance knowledge
before a CBR system can be regarded as fully operational. Domain experts
are one resource for the knowledge required for these containers,
automated learning methods another. Researchers are looking at automated
or semi-automated tools / approaches to assist experts whereby knowledge
can be acquired and integrated into CBR systems. Ideally these tools
should facilitate the initial acquisition of knowledge as well as
its long-term maintenance as the CBR system evolves within its environment.
Additionally they should consider the impact that knowledge in one
container has on another container - an issue which few researchers
have pursued. Authoring support tools are an exciting and challenging
area of development within CBR and one where progress must be made
over the forthcoming years to enable CBR to live up to the expectations
placed upon it and advance its commercial viability.
The workshop aims to
provide a forum whereby researchers can present and discuss current
tools and techniques which can be used to address the issues above
as well as to support the stimulation of new ideas and approaches.
These issues will form
the primary focus of the workshop. Key questions include (not exhaustively)
General
-
What are the sources for knowledge
in CBR?
-
What are the relationships between
the different types of Knowledge in CBR?
-
How much should we try to automate
the development and maintenance of CBR systems?
-
Where should the domain expert’s knowledge
be utilised?
-
In what areas of acquisition and maintenance
can automated techniques be of most assistance to experts?
-
What methods are there for integrating
reasoning with uncertainty in CBR?
Case vocabulary Knowledge
- How can the optimal case representation
be determined for a particular domain?
-
How can results from the KA/KM communities
improve the modeling of case knowledge?
-
Should all cases be represented similarly
in a case-base?
- How much can this process be automated?
-
What role does ontology research have
for CBR?
Case knowledge
- How do you identify quality
cases?
- Can operational databases be utilised
in determining case structure?
- How can case extraction from documents,
structured logs and the World-Wide Web be automated or in other ways
supported?
- How to assess the quality of a case
base?
- How can visualisation tools help in
maintaining case-bases?
Maintenance knowledge
- How can knowledge in all containers
be kept up-to-date during the learning phase in CBR?
-
What techniques can be applied to knowledge
to rapidly take account of changes in the operational environment
of the system?
-
How can manual and automated maintenance
methods be combined?
-
What ‘measures’ can trigger when to
update?

Format of Workshop.
There will be three technical
sessions, each based around a common theme, where authors will present
their work. The presentations will be 15 minutes each, plus 5 minutes
for specific questions pertaining to the presentation. At specific
intervals there will be opportunity for a discussion on the theme
of the Technical Session. The themes will be chosen based on the submissions
made to the workshop.

Attendance.
All participants
must register for the entire conference. We are trying to avoid charging
an extra fee for the workshops; this decision will be finalized later.
For a paper to be included in the workshop at least one author must
be present to present the work.

Submission
Requirements.
Max of 6 pages formatted to conference
specification. Further Information on this can be found at the ICCBR-01
web site
Papers will be reviewed by the program
committee for relevance to the workshop, quality, writing style and
innovation. Papers selected for publication in the workshop proceedings
will be published as Technical Reports of the Navy
Center for Applied Research in Artificial Intelligence (NCARAI)
of the Naval Research Laboratory (NRL)
It is also our
intention to follow up the workshop with a special issue on the topic
in an international journal.
