"From KRITON to IRMA:
Two Paradigms for Automated Knowledge Acquisition"
GMD's project KRITON is concerned with basic research in the domain of
automated and computer-supported knowledge acquisition. After a short
presentation of GMD and its Institute for Applied Information Technology we
will describe the projects of the expert system research group that
constitute the context of the KRITON project.
I will first present and critique the knowledge-acquisition system KRITON
that integrates two techniques originating from cognitive psychology, i.e.
interview techniques and protocol analysis. The KRITON-system is based on
a bottom-up approach, i.e. it focuses on the support of rapid prototyping.
The second approach I will present is based on the KADS-knowledge-models
(Knowledge Acquisition and Design Structuring) and on our experience with
the techniques that were originally developed for the KRITON-system. This
approach is best described as model-guided knowledge acquisition. The
system that will result from the integration of knolwedge-modeling with
knowledge acquisition will be called IRMA (Interpretation, Representation,
Modeling and Acquisition). IRA-grid (Interpretation, Representation and
Acquisition using repertory-grids) is the first component of IRMA. It is a
knowledge-acquisition tool that tries to acquire the knowledge needed for
hypothesis-selection processes.
