The Theory of Conceptual Spaces is a theory about concept representation proposed by Peter Gärdenfors. It is motivated by the notions like conceptual similarity and prototype theory. A ''conceptual space'' is multi-dimensional feature space where ''points'' denote objects, and ''regions'' denote concepts. Its bases are composed by ''quality dimensions'', which denote basic features in which concepts and objects can be compared, as such as ''weight'', ''colour'', ''taste'' and so on. The theory also puts forward the notion that ''natural'' categories are convex regions in a conceptual spaces. In that if and are elements of a category, and if is between and , then is also likely to belong to the category. The notion of concept convexity allow the interpretation of the focal points of regions as category prototypes. In the more general formulations of the theory, concepts are defined in terms conceptual similarity to their prototypes. ==See also== *Cognitive architecture *Commonsense reasoning *Conceptual dependency theory *Prototype Theory *Similarity (psychology) *Semantic hashing *Vector space model *Image schema *Global Workspace Theory 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Conceptual Spaces」の詳細全文を読む スポンサード リンク
