Our approach is based on the idea of repairing the mapping according to the usual principle of minimal change and on a recent, mapping-based notion of consistency of the specification. We define and analyze two notions of mapping repair under ontology and source schema update. We then present a set of results on the complexity of query answering in the above framework, when the ontology is expressed in DL-LiteR.<\/jats:p>","DOI":"10.24963\/ijcai.2017\/161","type":"proceedings-article","created":{"date-parts":[[2017,7,28]],"date-time":"2017-07-28T09:14:07Z","timestamp":1501233247000},"page":"1160-1166","source":"Crossref","is-referenced-by-count":8,"title":["Mapping Repair in Ontology-based Data Access Evolving Systems"],"prefix":"10.24963","author":[{"given":"Domenico","family":"Lembo","sequence":"first","affiliation":[{"name":"Sapienza universit\u00e0 di Roma"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Riccardo","family":"Rosati","sequence":"additional","affiliation":[{"name":"Sapienza Universit\u00e0 di Roma"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerio","family":"Santarelli","sequence":"additional","affiliation":[{"name":"Sapienza Universit\u00e0 di Rome"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Domenico Fabio","family":"Savo","sequence":"additional","affiliation":[{"name":"Sapienza Universit\u00e0 di Rome"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Evgenij","family":"Thorstensen","sequence":"additional","affiliation":[{"name":"University of Oslo"}],"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":"2017-07-28T11:52:33Z","timestamp":1501242753000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2017\/161"}},"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\/161","relation":{},"subject":[],"published":{"date-parts":[[2017,8]]}}}
