As a fragment of the Semantic Web Rule Language SWRL, DL rules allow for a tight integration with DL knowledge bases. In contrast to SWRL, however, the combination of DL rules with expressive description logics remains decidable, and we show that the DL &amp;Sscr;&amp;Rscr;&amp;Oscr;&amp;Iscr;&amp;Qscr; &amp;ndash; the basis for the ongoing standardisation of OWL 2 &amp;ndash; can completely internalise DL rules. On the other hand, DL rules capture many expressive features of &amp;Sscr;&amp;Rscr;&amp;Oscr;&amp;Iscr;&amp;Qscr; that are not available in simpler DLs yet. While reasoning in &amp;Sscr;&amp;Rscr;&amp;Oscr;&amp;Iscr;&amp;Qscr; is highly intractable, it turns out that DL rules can be introduced to various lightweight DLs without increasing their worst-case complexity. In particular, DL rules enable us to significantly extend the tractable DLs &amp;Escr;&amp;Lscr;++and DLP.<\/jats:p>","DOI":"10.3233\/978-1-58603-891-5-80","type":"book-chapter","created":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T11:59:50Z","timestamp":1740398390000},"source":"Crossref","is-referenced-by-count":1,"title":["Description Logic Rules"],"prefix":"10.3233","author":[{"family":"Kr&ouml;tzsch Markus","sequence":"additional","affiliation":[]},{"family":"Rudolph Sebastian","sequence":"additional","affiliation":[]},{"family":"Hitzler Pascal","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2008"],"original-title":[],"deposited":{"date-parts":[[2025,2,24]],"date-time":"2025-02-24T12:05:21Z","timestamp":1740398721000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0922-6389&volume=178&spage=80"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-58603-891-5-80","relation":{},"ISSN":["0922-6389"],"issn-type":[{"value":"0922-6389","type":"print"}],"subject":[],"published":{"date-parts":[[2008]]}}}
