           **** CALL FOR PARTICIPATION ****

``IJCAI Workshop ``Object-Based Representation Systems''

             Chambery (August 28th 1993)
------------------------------------------------------

The goal of the workshop is to study the notion of ``object'' as a
knowledge grain in knowledge-based systems.
A first category of object-based representation systems mainly
includes terminological (or description) logics.
People working in this area are more interested in studying and using
declarative representations.
A second category includes hybrid systems that rely on frame-based
languages and object-oriented programming.
People working in this area are more interested by the representation
and the use of procedural components.
Thus, the topics of interest of the workshop are the following:
- objects in knowledge representation: concepts, frames, classes.
- links between description logics and hybrid systems (frame-based or
class-based systems).
- fundamental relationships: specialization/generalization,
subsumption, part-whole, other partial orderings and equivalence
relations.
- objects, constraints and other relations: temporal and spatial
relations, general constraints (equalities, inequalities).
- representation of procedural knowledge: reflexes (demons), methods.
- reasoning with objects: inheritance, classification-based reasoning,
truth maintenance.

The workshop is intended to be a challenge to understand the
contributions of the more logical and more procedural approaches.
Participants will try to develop guidelines for interpreting the
usefulness of each approach.
They will also be encouraged to exchange different points of
view, and possibly, to define a more complete and universal
object-based representation formalism integrating the two approaches.

------------------------------
Participation and Organization
------------------------------

Participation will be of two kinds: speaker and regular participant.
People interested in attending the workshop must send a position
paper, 1 or 2 pages for regular participant, up to 10 pages for
speakers.
Selected papers will be published in the proceedings of the workshop.

Submissions should be made preferably by email.
For those who do not have access to email (or any other reason), send
4 copies of your position paper to the chairman of the workshop.

The workshop registration fee is 300 FF, and includes coffee breaks
(note that every workshop participant must have registered for the
main conference).

--------
Schedule
--------

- Position papers must be sent to the chairman before March 1993, 1st.
- The decisions of the program committee will be notified to the
selected speakers and regular participants before April, 15th.
- Final papers are due before June, 1st, to be published in the
proceedings of the workshop.
It is intended that preprints of the workshop will be mailed to
participants before the workshop.
