  10. Conceptual Spaces [Gärdenfors2000]  Quality dimensions  Interpretable ways of judging the similarity of two instances  E.g., temperature, weight, brightness, pitch [Gärdenfors2000] Gärdenfors, P. Conceptual Spaces: The Geometry of Thought. MIT press , 2000 A Thorough Formalization of Conceptual Spaces / Bechberger and Kühnberger 10

  11. Conceptual Spaces [Gärdenfors2000]  Quality dimensions  Interpretable ways of judging the similarity of two instances  E.g., temperature, weight, brightness, pitch  Domain  Set of dimensions that inherently belong together  Color: hue, saturation, and brightness [Gärdenfors2000] Gärdenfors, P. Conceptual Spaces: The Geometry of Thought. MIT press , 2000 A Thorough Formalization of Conceptual Spaces / Bechberger and Kühnberger 11

  12. Conceptual Spaces [Gärdenfors2000]  Quality dimensions  Interpretable ways of judging the similarity of two instances  E.g., temperature, weight, brightness, pitch  Domain  Set of dimensions that inherently belong together  Color: hue, saturation, and brightness  Distance in this space is inversely related to similarity  Within a domain: Euclidean distance  Between domains: Manhattan distance [Gärdenfors2000] Gärdenfors, P.

Conceptual Spaces [Gärdenfors2000]  Quality dimensions  Interpretable ways of judging the similarity of two instances  E.g., temperature, weight, brightness, pitch  Domain  Set of dimensions that inherently belong together  Color: hue, saturation, and brightness  Distance in this space is inversely related to similarity  Within a domain: Euclidean distance  Between domains: Manhattan distance  Concepts  Region + correlation information + salience weights [Gärdenfors2000] Gärdenfors, P.
