abstract = {The metric and dimensional assumptions that underlie the
geometric representation of similarity are questioned on both
theoretical and empirical grounds. A new set-theoretic approach to
similarity is developed in which objects are represented as collections
of features, and similarity is described as a feature-matching process.
Specifically, a set of qualitative assumptions is shown to imply the
contrast model, which expresses the similarity between objects as a
linear combination of the measures of their common and distinctive
features. Several predictions of the contrast model are tested in the
studies of similarity with both semantic and perceptual stimuli. The
model is used to uncover, analyze, and explain a variety of empirical
phenomena such as the role of common and distinctive features, the
relations between judgments of similarity and difference, the presence
of asymmetric similarities, and the effects of context on judgments of
similarity. The contrast model generalizes standard representations of
similarity data in terms of clusters and trees. It is also used to
analyse the relations of prototypicality and family resemblance.},
