A conceptual space is a geometric structure that represents a number of quality dimensions, which denote basic features by which concepts and objects can be compared, such as weight, color, taste, temperature, pitch, and the three ordinary spatial dimensions. [ 1][ 2]: 4 In a conceptual space, points denote objects, and regions denote concepts.

A 'Conceptual Space' refers to theoretical entities that can be used to explain and predict various empirical phenomena concerning concept formation. It is a multi-dimensional representation of concepts, where each dimension represents a different characteristic or property associated with the concept.

A conceptual space is built up from geometrical structures based on a number of quality dimensions. The main applications of the theory are on the constructive side of cognitive science: as a constructive model the theory can be applied to the development of artificial systems capable of solving cognitive tasks.
