EVALUATING A CASE-BASED DISCOVERY SYSTEM - A CASE-STUDY IN CONTENT-ORIENTED EVALUATION

Research in case-based reasoning has explored the ideas of retrieving and adapting previous experience in the form of cases. The retrieval p rocess uses an index vocabulary which attempts to capture content and context of previous cases. Current approaches to empirical evaluation of case-based reasoning systems often do not consider the crucial role which a content-oriented index vocabulary plays in the various stages of the case-based reasoning process. We will address this issue by de scribing an evaluation of our case-based discovery system IULIAN. Base d on this description, we will propose a general schema for content-or iented evaluation of case-based reasoning systems. (C) 1998 Elsevier S cience B.V.
