Abstract:
CBR seems well suited to fault diagnosis because
diagnostic episodes naturally form cases and much of
expert competence seems to be based on reuse of old
solutions. However, in many diagnosis problems it is
difficult to compile a complete case description in
advance, consequently the conventional one-shot case
retrieval methodology will not work. In this paper we
introduce a set of fault diagnosis problems that have this
characteristic and we describe a model-based goal-driven
system that produces focused questions that request extra
information required for diagnosis. The central
contribution in this paper is a description of a CBR system
that also has this characteristic of producing focused
questions in diagnosis. We describe the information
theoretic mechanism that allows the CBR system to do
this and we present an evaluation of the CBR system and a
comparison of the two systems.
