Wikibase as an infrastructure for Knowledge Graphs: The EU Knowledge Graph
10-31, 10:00–10:25 (UTC), Room 1

Knowledge graphs are being deployed in many enterprises and institutions. An easy-to-use, well-designed infrastructure for such knowledge graphs is not obvious. After the success of Wikidata, many institutions are looking at the software infrastructure behind it, namely Wikibase.

In this paper we detail how Wikibase is used as the infrastructure behind the EU Knowledge Graph. This graph, which is deployed at the European Commission, integrates different structured information about the European Union.

We will show: the current content of the graph, how the knowledge is ingested, how it is maintained up to date, how the data is connected with Wikidata and what services are constructed around.
