- IJCAI'93 Workshop on a Problem-Solving Perspective on Explanation
- *****************************************************************
-
- The IJCAI Workshop on a Problem-Solving Perspective on Explana-
- tion will be held during the Thirteenth International Joint
- Conference on Artificial Intelligence in Chambery, France. The
- one day workshop will bring together active researchers in
- several areas of automated explanation. The goal of the workshop
- is to study the explanation of knowledge-based systems from a
- "problem-solving" perspective. Explanation will be analyzed for
- impact from (1) the problem that is solved, (2) the model used to
- represent the target artifact, and (3) the method used to direct
- the problem solving.
-
- Explanation has grown from a by-product of the development of
- knowledge-based systems to an important element of a knowledge-
- based system's requirements specification. Researchers and prac-
- titioners alike have realized, often in retrospect, that the ex-
- planatory capabilities of a knowledge-based system are dependent
- on a combination of the problem being solved (e.g., diagnosis
- versus design), the model used to represent the artifact (e.g.,
- functional versus structural), and the method used to direct
- problem solving (e.g., generate-and-test versus cover-and-
- differentiate). The result is an explanation matrix indexed by
- problem, model, and method types. Although the specific indices
- and dimensions may vary, a sample explanation matrix is shown be-
- low.

- METHOD
-
- Many explanation systems have been developed within this matrix.
- However, there has been little study of the explanation matrix
- itself. This workshop will focus on analysis and comparison of
- individual cells within this matrix. For example, analysis may
- show that the problem type (e.g., diagnosis) determines a set of
- things that need to be explained, while the method and model
- used to solve the problem (e.g., a cover-and-differentiate use of
- causal knowledge) make some things easy or hard to explain. Such
- an analysis will lead to conclusions such as "diagnosis requires
- explanations for x, y, and z; the cover-and-differentiate ap-
- proach using causal knowledge supplies comparative explanations
- for x and y, but not z.".
-
- The workshop will (1) collectively propose a matrix that leads
- to a useful and interesting partitioning of the explanation work
- in knowledge-based systems; (2) propose and evaluate hypotheses
- concerning the impact of matrix cells on explanatory ability; (3)
- serve as a collection of case studies addressing the construction
- of explanation facilities within an explicit "problem-solving"
- perspective.
-
- Researchers interested in participating in the IJCAI Workshop on
- a Problem-Solving Perspective on Explanation should submit six
- (6) copies of a paper describing their research no later than
- March 1, 1993. Papers must be original and are limited to 10
- pages. The title page of the paper must explicitly include the
- problem, model, and method used to place the work in the explana-
- tion matrix. The specific indices, for example diagnosis versus
- design, may be any indices deemed appropriate by the authors of
- the paper. A "readings in" style book is anticipated as a result
- of this workshop.
-
- Important deadlines are as follows:
-
- submissions due : March 1, 1993
- author notification : April 15, 1993
- final papers received : June 15, 1993
- preprints distributed : July 15, 1993
