Title

wiki2rdf: Automatische Extraktion von RDF-Tripeln aus Artikelvolltexten der Wikipedia

Source

Abstract

Im Projekt DBpedia werden unter anderem Informationen aus Wikipedia-Artikeln in RDF-Tripel umgewandelt. Dabei werden jedoch nicht die Artikeltexte berücksichtigt, sondern vorrangig die sogenannten Infoboxen, die Informationen enthalten, die bereits strukturiert sind. Im Rahmen einer Masterarbeit am Institut für Bibliotheks- und Informationswissenschaft der Humboldt-Universität zu Berlin wurde wiki2rdf entwickelt, eine Software zur regelbasierten Extraktion von RDF-Tripeln aus den unstrukturierten Volltexten der Wikipedia. Die Extraktion erfolgt nach Syntax-Parsing mithilfe eines Dependency-Parsers. Exemplarisch wurde wiki2rdf auf 68820 Artikel aus der Kategorie "Wissenschaftler" der deutschsprachigen Wikipedia angewandt. Es wurden 244563 Tripel extrahiert.
