Using ter-Horst\u2019s pD* fragment of OWL as a base, the authors compose a rule-based framework for application to web data: they argue their decisions using observations of undesirable examples taken directly from the Web. The authors further temper their OWL fragment through consideration of \u201cauthoritative sources\u201d which counter-acts an observed behaviour which they term \u201contology hijacking\u201d: new ontologies published on the Web re-defining the semantics of existing entities resident in other ontologies. They then present their system for performing rule-based forward-chaining reasoning which they call SAOR: Scalable Authoritative OWL Reasoner. Based upon observed characteristics of web data and reasoning in general, they design their system to scale: the system is based upon a separation of terminological data from assertional data and comprises of a lightweight in-memory index, on-disk sorts and file-scans. The authors evaluate their methods on a dataset in the order of a hundred million statements collected from real-world Web sources and present scale-up experiments on a dataset in the order of a billion statements collected from the Web.<\/p>","DOI":"10.4018\/jswis.2009040103","type":"journal-article","created":{"date-parts":[[2013,2,5]],"date-time":"2013-02-05T17:36:22Z","timestamp":1360085782000},"page":"49-90","source":"Crossref","is-referenced-by-count":47,"title":["Scalable Authoritative OWL Reasoning for the Web"],"prefix":"10.4018","volume":"5","author":[{"given":"Aidan","family":"Hogan","sequence":"first","affiliation":[{"name":"National University of Ireland, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Harth","sequence":"additional","affiliation":[{"name":"National University of Ireland, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Polleres","sequence":"additional","affiliation":[{"name":"National University of Ireland, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","container-title":["International Journal on Semantic Web and Information Systems"],"original-title":[],"language":"ng","link":[{"URL":"https:\/\/www.igi-global.com\/viewtitle.aspx?TitleId=4114","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T11:59:18Z","timestamp":1654084758000},"score":1,"resource":{"primary":{"URL":"https:\/\/services.igi-global.com\/resolvedoi\/resolve.aspx?doi=10.4018\/jswis.2009040103"}},"subtitle":[""],"short-title":[],"issued":{"date-parts":[[2009,4,1]]},"references-count":0,"aliases":["10.4018\/ijswis.2009040103"],"journal-issue":{"issue":"2","published-print":{"date-parts":[[2009,4]]}},"URL":"https:\/\/doi.org\/10.4018\/jswis.2009040103","relation":{},"ISSN":["1552-6283","1552-6291"],"issn-type":[{"value":"1552-6283","type":"print"},{"value":"1552-6291","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,4,1]]}}}
