Ontological reasoning for many fragments of OWL 2 can be reduced to the evaluation of Datalog queries. This paper surveys some of these compilations, and in particular the one addressing queries over Horn-SHIQ knowledge bases and its implementation in DLV2 enanched by a new version of the Magic Sets algorithm.<\/jats:p>","DOI":"10.3233\/ssw200045","type":"book-chapter","created":{"date-parts":[[2020,11,13]],"date-time":"2020-11-13T13:18:18Z","timestamp":1605273498000},"source":"Crossref","is-referenced-by-count":0,"title":["Large-Scale Ontological Reasoning via Datalog"],"prefix":"10.3233","author":[{"given":"Mario","family":"Alviano","sequence":"first","affiliation":[{"name":"University of Calabria, Rende, Italy, e-mail: alviano@mat.unical.it, manna@mat.unical.it"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marco","family":"Manna","sequence":"additional","affiliation":[{"name":"University of Calabria, Rende, Italy, e-mail: alviano@mat.unical.it, manna@mat.unical.it"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Studies on the Semantic Web","Applications and Practices in Ontology Design, Extraction, and Reasoning"],"original-title":[],"link":[{"URL":"http:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/SSW200045","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,11,13]],"date-time":"2020-11-13T13:18:18Z","timestamp":1605273498000},"score":1,"resource":{"primary":{"URL":"http:\/\/ebooks.iospress.nl\/doi\/10.3233\/SSW200045"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,11,12]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/ssw200045","relation":{},"ISSN":["1868-1158","2215-0870"],"issn-type":[{"value":"1868-1158","type":"print"},{"value":"2215-0870","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,11,12]]}}}
