However, a number of studies have found that people do not follow this set-theoretic account when classifying items in certain natural-language conjunctions. For example, Hampton<jats:sup>1<\/jats:sup> found that while people tend to classify 'toucans' as non-members of the single category 'pet', they classify 'toucans' as members of the conjunction 'pet bird'. This paper describes a general approach to category conjunction that gives a logically consistent explanation for the occurrence of overextension in these conjunctions. The paper also describes a computational model implementing this approach, and an experiment using conjunctions of controlled, laboratory-learned categories to test this model. This computational model gave a good fit to both classification and overextension results in the experiment. The approach to conjunction implemented in this model may provide a useful tool for AI models of classification, allowing them to reason about category conjunction in a way that reflects human reasoning. <\/jats:p>","DOI":"10.1142\/s0218213005001990","type":"journal-article","created":{"date-parts":[[2005,5,12]],"date-time":"2005-05-12T11:59:43Z","timestamp":1115899183000},"page":"61-76","source":"Crossref","is-referenced-by-count":0,"title":["CLASSIFICATION IN CATEGORY CONJUNCTION: THE LOGIC OF OVEREXTENSION"],"prefix":"10.1142","volume":"14","author":[{"given":"FINTAN J.","family":"COSTELLO","sequence":"first","affiliation":[{"name":"Department of Computer Science, University College Dublin, Belfield, Dublin 6, Ireland"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.3758\/BF03197712"},{"key":"rf2","volume-title":"Metamathematics of Fuzzy Logic","author":"Hajek P.","year":"1988"},{"key":"rf3","volume-title":"Rule-based Expert Systems: The MYCIN experiments of the Stanford Heuristic Programming Project","author":"Buchanan B.
