....is straightforward: given a set of classified examples, which are described as points in an input space, a new unclassified example is assigned to the known class of the nearest example. The nearest relation is computed using a (similarity) metric defined on the input space. Many researchers [21 23, 11, 1, 2, 14, 13, 18, 19, 7, 25] focused their attention on the use of local metrics, i.e. metrics that vary depending on the position of the points in the input space. Conversely, more traditional global metrics assume that similarity evaluation should be independent from the area of the input space the cases to be compared are ....

....useful for CCBR tools. For example, hq,ai pairs in case states are often annotated with weights, similar to feature weights, so as to bias the similarity function. A machine learning approach could be used to automatically tune these weights, as has been done for classification and planning tasks (Wettschereck et al. 1997; Mu noz Avila Hullen, 1996) This would further simplify the case authoring task, allowing users to ignore the challenging problem of assigning weights manually.
