Using this formalism, the answers for a given query to an ontology can be ranked by preference, allowing users to retrieve the most preferred answers only. We provide a host of complexity results for the main computational tasks in this framework, for the general case, and for EL and DL-Lite_core as underlying ontology languages.<\/jats:p>","DOI":"10.24963\/ijcai.2017\/131","type":"proceedings-article","created":{"date-parts":[[2017,7,28]],"date-time":"2017-07-28T05:14:07Z","timestamp":1501218847000},"page":"943-949","source":"Crossref","is-referenced-by-count":0,"title":["Query Answering in Ontologies under Preference Rankings"],"prefix":"10.24963","author":[{"given":"\u0130smail \u0130lkan","family":"Ceylan","sequence":"first","affiliation":[{"name":"Technische Universit\u00e4t Dresden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Lukasiewicz","sequence":"additional","affiliation":[{"name":"University of Oxford"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Pe\u00f1aloza","sequence":"additional","affiliation":[{"name":"Free University of Bozen-Bolzano"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oana","family":"Tifrea-Marciuska","sequence":"additional","affiliation":[{"name":"The Alan Turing Institute, London"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"number":"26","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)","University of Technology Sydney (UTS)","Australian Computer Society (ACS)"],"acronym":"IJCAI-2017","name":"Twenty-Sixth International Joint Conference on Artificial Intelligence","start":{"date-parts":[[2017,8,19]]},"theme":"Artificial Intelligence","location":"Melbourne, Australia","end":{"date-parts":[[2017,8,26]]}},"container-title":["Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2017,7,28]],"date-time":"2017-07-28T07:52:24Z","timestamp":1501228344000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2017\/131"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2017,8]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2017\/131","relation":{},"subject":[],"published":{"date-parts":[[2017,8]]}}}
