Views on Wikipedia In 2006 he noted the importance of Wikipedia as an addressable knowledge base: Wikipedia makes it easy to include in any online communications a pointer to more knowledge on any topic using a convenient stable URL. "The economy and convenience of doing this is enormous", he said.

In 2012 he noted: "Wikipedia is already an 'addressable knowledge base', which creates huge value. DBpedia aims to add structure to this. Perhaps more importantly, Wikidata is an initiative to create a machine- and human-readable knowledge base of all the entities in Wikipedia and allow them to be augmented with further data and links."
