Definition Object Category/Category/Word/Gärdenfors: an object category is defined by the following elements:
(i) a set of relevant domains (possibly increased in the course of time)
(ii) a set of convex regions in these domains (possibly a region is identical to the entire domain).
(iii) weighting of the salience of the domains (context-dependent)
(iv) information on how the regions of different domains are related.
(v) information on the part-whole relations.
Hierarchy of object categories: is reflected in language and cognition. There are three types of generalization:
(i) including convex regions of domains
(ii) reduction of the part-to-whole relations for a category
(iii) reduction of the domains associated with a category.
E.g. a plastic duck only shares the form with the biological concept of the duck. The generalized term is then "duck-shaped object"._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
