Conference on Second Generation Expert Systems

Call for Papers

For the third consecutive year, one of the AVIGNON conferences will be
devoted to the study of Second Generation Expert Systems.

The term "second generation" expert systems is used to characterize
knowledge-based systems able to solve problems by combining different
types of reasoning. Such systems often use multiple representations of
the problem to develop different problem-solving strategies.

The first generation expert systems were largely based on heuristic,
associational rules. To overcome their limitations, a new line of
research was begun into the use of deeper knowledge, often referred
to as "model-based", "causal" or "qualitative" reasoning.
Since model-based and heuristic approaches appear to be largely
complementary, recent work has begun to combine these two reasoning
processes into a single problem-solver.

Another thread of research has been aimed at making the problem solving
methods used much more explicit and elaborating "task-specific
architectures". Research has then been conducted into designing
particular problem-solvers by combining multiple generic or primitive
task-specific architectures.

Second Generation Expert Systems are intended to have those two approches
converge. Building systems that make explicit the tasks to be realized,
the problem solving methods to be implemented and the associated domain
models would appear to be the basic objective of this new field. And
because a non-trivial problem can only be solved by bringing a number of
different resolution methods and domain models into play, the cooperation
and integration of these methods and models is one of the key problems
to be met in the building of such systems.


The Program Committee is seeking papers on the following themes (list non

+ combining different reasoning types
+ architectures integrating heuristic and model-based reasoning;
+ reasoning with multiple models;
+ multi-expert, multi-agent cooperation;
+ cooperation of distributed problem-solvers;
+ task-specific architectures;
+ knowledge acquisition, explanation, validation, in second generation
expert systems;
+ the use of qualitative, model-based, causal or temporal reasoning to
supplement heuristic reasoning;
+ integrating qualitative and quantitative reasoning;
+ applications of these techniques to real-world problems
(e.g. diagnosis, design, scheduling).

Papers describing applications should outline the strengths as well as
the weaknesses of the implemented systems. In particular, examples and
analysis of failures will be appreciated in order to delineate the
applicability of the methods.

Theoretical papers should be clearly related to previous work and should
enlighten the advantages and originality of the proposed approach.


Authors should submit 6 copies of their papers before January 7, 1991
