| Abstract | . In [9] we introduced a formal framework for constructing ordinal similarity measures, and suggested how this might also be applied to cardinal measures. In this paper we will place this approach in a more general framework, called similarity metrics. In this framework, ordinal similarity metrics (where comparison returns a boolean value) can be combined with cardinal metrics (returning a numeric value) and, indeed, with metrics returning values of other types, to produce new metrics. 1 Introduction In this paper we present a formal framework for the construction of similarity metrics, which subsume a number of ways of measuring similarity. In particular similarity measures that return boolean values, numeric values and structured data can all be modelled by similarity metrics. 1.1 An Example Case Base We shall use the small example case base in Fig. 1 throughout this paper. Each case represents a holiday and has three attributes --- the destination, the price and the activities ava... |
