....that learns to index cases on the basis of their adaptability, overriding semantic similarity where appropriate, a proposal that has been implemented by Fox Leake [4] Their system avoids cases with feature combinations that were difficult to adapt in previous problem solving episodes. Leake s [5] method of constructive similarity also addresses the fundamental importance of adaptability in case retrieval. Cases matched is not viewed as from the viewpoint of known and fixed base and target feature sets, but is instead viewed as an elaborative process where initial target features are ....

....The second approach is more favorable because of flexibility it provides and because it gives us additional information for relevance judgment. It is this additional information which allows us to answer the question how are the items similar . Similarity theories developed so far (e.g. [Tve77, Hol85, Lea92, SOS92, Mic93]) do not support relevance assessment if the context is changed. In order to support flexible retrieval of relevant information, we include context in our definition of similarity. 2 The Role of Context Similarity judgments are always made with respect to representations of entities, not with ....

.... adaptation during retrieval (in section 5 we show that it can even be more efficient than conventional methods) The idea that retrieval should be sensitive to adaptation requirements has been mooted before (see Birnbaum et al. 1989; Fox Leake, 1995; Goel, 1989; Keane, 1993; Kolodner, 1989; Leake, 1992). Kolodner (1989) argues that some classes of matches, easily adapted matches, should be preferred over hard to adapt matches during retrieval. Similarly, Goel s KRITIK system (Goel, 1989) prefers candidate design cases that satisfy the functional specifications of the target design and hence ....

....features are required for retrieving easily adaptable cases from memory. Because the quality of a retrieval scheme depends on retrieving cases that are easy to adapt, it is desirable to achieve more direct connections between similarity criteria and case adaptation ability in CBR systems (e.g. [16, 19]) our research is one way to make indexing criteria better reflect adaptability. In addition, introspective reasoning for self improvement is a general approach that could be extended to other portions of the CBR process: altering adaptation, evaluation, and case storage (See [9] for a more ....

....for similarity assessment. As has been pointed out by a number of researchers, the goal of similarity assessment in CBR is to select the prior cases that can be most easily applied to the new situation. As a result, useful similarity judgments must reflect adaptability (Birnbaum et al. 1991; Leake 1992; Smyth Keane 1996) Because DIAL s rule based case adaptation is augmented with case based adaptation, which enables learning how to perform adaptations, adaptability of cases changes with adaptation learning so similarity judgments must change as well. This led us to investigate case based ....
