Explanation-Driven Retrieval, Reuse and Learning of Cases
Agnar Aamodt · 1993
. A method for integrated case-based and generalization-based reasoning and learning is described. The primary role of general domain knowledge is to provide explanatory support for the case-based processes. A general explanation engine - the ACTIVATE-EXPLAIN-FOCUS cycle - utilizes a presumably rich, multirelational knowledge model in producing context-dependent explanations. 1. Introduction Case-based reasoning covers a wide variety of methods. While some methods emphasize problem solving and learning by use of specific cases instead of general domain knowledge, others use general knowledge 1 combined with cases. Among the latter, various approaches to what types of general knowledge to incorporate, as well as to how general knowledge is used, are taken. General knowledge may be used for an additional problem solving method, e.g. a method that is applied if the case-based method fails, and/or it may be used within the case-based method itself. The general knowledge may be of a s...
