About the webinar

Knowledge Graphs have become a common asset for representing world knowledge in data driven models and applications. Wikidata is one of the largest crowdsourced Knowledge Graphs, with over 90 million entities and 1.5 billion edges. In this webinar, participants will learn how heterogeneous facts are represented in Wikidata, and how to retrieve them by using standard query languages and tools designed by the Wikidata community. The audience will learn about: 1) The Wikidata data model, 2) The features of the Wikidata SPARQL endpoint and tooling; and 3) Query examples to retrieve qualifiers, references, rankings and deprecated statements in Wikidata.
