Demo – Paper 466
Wikidata as a collaborative Semantic Web data source has enjoyed increasing prominence, storing over 150 mio facts about more than 26 mio entities. Yet missing is a way to assess its completeness. In this demo we present COOL-WD, a tool for supporting the completeness lifecycle of Wikidata, that is, the creation, view, update, and consumption of metadata about Wikidata completeness. COOL-WD is available at http://cool-wd.inf.unibz.it/ and has so far collected more than 10,000 completeness statements.
