A Software Engineering Model for Case Memory Systems
Andrew M. Dearden · The Computer Journal · 1997
This paper describes a generic model for case memory systems expressed using the Z notation. A case memory system is an essential part of any case-based reasoning system, and provides a mechanism for storing old cases, and for assessing the relationship between the stored cases and a new problem. Using the model, characteristics that have been claimed for specific case memory systems in the literature, e.g. responsiveness to a reasoner's goals or use of past experience in case assessment, are expressed formally in terms of constraints on the means by which case relations are computed. The model supports precise reasoning about the characteristics of specific systems and offers insight into the variety of options available to software or knowledge engineers seeking to reuse a case memory system, to select a case memory system shell or to develop a new system.
