EventKG: A Multilingual Event-Centric Temporal Knowledge Graph

The EventKG is a novel multilingual resource incorporating event-centric information extracted from several large-scale knowledge graphs such as Wikidata, DBpedia and YAGO, as well as less structured sources such as the Wikipedia Current Events Portal and Wikipedia event lists in five languages. The EventKG is an extensible event-centric resource modeled in RDF. It relies on Open Data and best practices to make event data spread across different sources available through a common representation and reusable for a variety of novel algorithms and real-world applications.

Statistics (Version V1.1)

EventKG provides information for over 690 thousand events and over 2,3 million temporal relations. Nearly a half of the events (46.98%) originate from the existing knowledge graphs; the other half (53.02%) is extracted from semi-structured sources.
