The dbpedia project started by AKSW (together with Chris Bizer from FU Berlin and OpenLink Software) is getting increasingly popular. No wonder, since the over 10 Mio. RDF triples extracted from the English Wikipedia allow the astonishing answering of previously hard-to-answer questions. Who for example knows what connects Leipzig with Innsbruck?
