Abstract. 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. Resource type: Dataset Permanent URL: http://eventkg.l3s.uni-hannover.de
the construction of the temporal knowledge graph is the work by Gottschalk and Demidova REF (2018): they present a temporal knowledge graph that integrates and harmonizes event-centric and temporal information regarding historical and contemporary events.
