Here we provide a concrete oracle with practical usage, namely for &amp;Escr;&amp;Lscr;+which is tractable for reasoning tasks like subsumption. We show that the defined oracle remains tractable (wrt. data complexity) so that the combined (query-driven) approach of non-monotonic rules with that oracle is tractable as well.<\/jats:p>","DOI":"10.3233\/978-1-60750-606-5-1079","type":"book-chapter","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T11:58:24Z","timestamp":1740398304000},"source":"Crossref","is-referenced-by-count":0,"title":["Querying in &amp;Escr;&amp;Lscr;"],"prefix":"10.3233","author":[{"family":"Knorr Matthias","sequence":"additional","affiliation":[]},{"family":"Alferes Jos&eacute; J&uacute;lio","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2010"],"original-title":[],"deposited":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T12:25:19Z","timestamp":1740399919000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=215&spage=1079"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-60750-606-5-1079","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2010]]}}}
