The Prototype Resemblance Theory of Disease

Journal of Medicine and Philosophy, 2008
In a previous paper the concept of disease was fuzzy-logically analyzed and a sketch was given of a prototype resemblance theory of disease (Sadegh-Zadeh (2000). J. Med. Philos., 25:605-38). This theory is outlined in the present paper. It demonstrates what it means to say that the concept of disease is a nonclassical one and, therefore, not amenable ...

A Bi-Prototype Theory of Facial Attractiveness

open access: yesNeural Computation, 2009
The attractiveness of human faces can be predicted with a high degree of accuracy if we represent the faces as feature vectors and compute their relative distances from two prototypes: the average of attractive faces and the average of unattractive faces.

A reassessment of the shift from the classical theory of concepts to prototype theory [PDF]

open access: yesCognition, 1994
A standard view within psychology is that there have been two important shifts in the study of concepts and that each has led to some improvements. The first shift was from the classical theory of concepts to probabilistic theories, the most popular of which is prototype theory. The second shift was from probabilistic theories to theory-based theories.

Fuzzy soil mapping based on prototype category theory

open access: yesGeoderma, 2006
An essential component of soil mapping is classification, a process of assigning spatial soil entities to predefined categories (classes). However, by their nature soils exist as a continuum both in the spatial and attribute domains and often cannot be ...

Prototype theory and compositionality

Cognition, 1995
Osherson and Smith (1981, Cognition, 11, 237-262) discuss a number of problems which arise for a prototype-based account of the meanings of simple and complex concepts. Assuming that concept combination in such a theory is to be analyzed in terms of fuzzy logic, they show that some complex concepts inevitably get assigned the wrong meanings.

On the adequacy of prototype theory as a theory of concepts

Cognition, 1981
Abstract Prototype theory construes membership in a concept's extension as graded, determined by similarity to the concept's “best” exemplar (or by some other measure of central tendency). The present paper is concerned with the compatibility of this view of concept membership with two criteria of adequacy for theories of concepts.
