Release of EventKG V3.0, Event-QA and EventKG+BT: Event-centric knowledge graph, question answering and biography timelines

Dear all,

We are happy to announce the release of EventKG V3.0 [1, 2] - a 
multilingual event-centric temporal knowledge graph and several related 
datasets and demonstrators.

EventKG is available at: http://eventkg.l3s.uni-hannover.de

What’s new? In V3.0, EventKG incorporates over 1.3 million contemporary 
and historical events and over 4.5 million temporal relations extracted 
from several large-scale knowledge graphs and semi-structured sources. 
These sources include Wikidata, DBpedia, YAGO, Wikipedia Event Lists and 
Wikipedia Current Events Portal. We provide data in 15 languages and 
include interlinking and provenance information.

Based on EventKG, we have created demonstrations and datasets for a 
number of use cases related to event-centric research, including:

- EventKG+BT (http://eventkg-biographies.l3s.uni-hannover.de) [3]: a 
timeline generation system that creates concise and interactive 
spatio-temporal representations of personal biographies from EventKG 
using distant supervision.
- Event-QA (http://eventkg.l3s.uni-hannover.de/eventqa.html) [4]: a 
dataset for answering event-centric questions over EventKG and DBpedia, 
with 1000 event-centric queries in English, German and Portuguese.

To get more information about these demonstrations and datasets, please 
have a look at the EventKG website (http://eventkg.l3s.uni-hannover.de).

Simon Gottschalk
