Scalable Authoritative OWL Reasoning for the Web

Abstract

AbstrAct In this article the authors discuss the challenges of performing reasoning on large scale RDF datasets from the Web. Using ter-Horst's 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 " authoritative stheirces " which counteracts an observed behavitheir which we term " ontology hijacking " : new ontologies published BLOCKINon BLOCKINthe BLOCKINWeb BLOCKINre-defining BLOCKINthe BLOCKINsemantics 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, BLOCKINon-disk BLOCKINsorts BLOCKINand BLOCKINfile-scans. BLOCKINThe BLOCKINauthors evaluate their methods on a dataset in the order of a hundred million statements collected from real-world Web stheirces and present scale-up experiments on a dataset in the order of a billion statements collected from the Web.
