  One of the key requirements to facilitate semantic analytics of information
regarding contemporary and historical events on the Web, in the news and in
social media is the availability of reference knowledge repositories containing
comprehensive representations of events and temporal relations. Existing
knowledge graphs, with popular examples including DBpedia, YAGO and Wikidata,
focus mostly on entity-centric information and are insufficient in terms of
their coverage and completeness with respect to events and temporal relations.
EventKG presented in this paper is a multilingual event-centric temporal
knowledge graph that addresses this gap. EventKG incorporates over 690 thousand
contemporary and historical events and over 2.3 million temporal relations
extracted from several large-scale knowledge graphs and semi-structured sources
and makes them available through a canonical representation.
