Document Summary

Mds: multidimensional scale model: similarity relations between entities in terms of a geometric model that consists of a set of points embedded in a dimensionally organized metric space. Similarity between a pair of objects is inversely related to the distance between the two objects" points in space. City-block: appropriate for psychologically separated dimensions like brightness and size of object. distance between two points in the sum of their distances on each dimension. The underlying idea of similarity is the spreading activation theory which is related to. The target object activates a concept and activation spreads to related concepts. The geometric model: basic assumption: psychological distance approximates physical distance, advantage of geometric model: easily built into a computational system, gives the researcher a way to generate a similarity space for a participant. Assumptions of geometric model that are often violated: Minimality: similarity between an object and itself is the same for all objects.
