These operators are generalizations of t-norms and t-conorms allowing the neutral element lying anywhere in the unit interval. It is shown that uninorms can be built up from t-norms and t-conorms by a construction similar to ordinal sums. De Morgan classes of uninorms are also described. Representability of uninorms is characterized and a general representation theorem is proved. Finally, pseudo-continuous uninorms are defined and completely classified. <\/jats:p>","DOI":"10.1142\/s0218488597000312","type":"journal-article","created":{"date-parts":[[2003,10,22]],"date-time":"2003-10-22T01:39:04Z","timestamp":1066786744000},"page":"411-427","source":"Crossref","is-referenced-by-count":593,"title":["Structure of Uninorms"],"prefix":"10.1142","volume":"05","author":[{"given":"J\u00e1nos C.","family":"Fodor","sequence":"first","affiliation":[{"name":"Institute of Mathematics and Computer Science, University of Agricultural Sciences (GATE), P\u00e1ter K. u. 1., H-2103 G\u00f6d\u00f6ll\u00f6, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ronald R.","family":"Yager","sequence":"additional","affiliation":[{"name":"Machine Intelligence Institute, Iona College, New Rochelle, NY 10801, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Rybalov","sequence":"additional","affiliation":[{"name":"Computer Science Department, Graduate Center of CUNY, New York, NY 10036, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"container-title":["International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S0218488597000312","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,8,7]],"date-time":"2019-08-07T17:20:38Z","timestamp":1565198438000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S0218488597000312"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1997,8]]},"references-count":0,"journal-issue":{"issue":"04","published-online":{"date-parts":[[2011,11,21]]},"published-print":{"date-parts":[[1997,8]]}},"alternative-id":["10.1142\/S0218488597000312"],"URL":"https:\/\/doi.org\/10.1142\/s0218488597000312","relation":{},"ISSN":["0218-4885","1793-6411"],"issn-type":[{"value":"0218-4885","type":"print"},{"value":"1793-6411","type":"electronic"}],"subject":[],"published":{"date-parts":[[1997,8]]}}}
