Talks and Events

The EU Knowledge Graph

The EU Knowledge Graph at the European Commission

The European Commission is maintaining a Knowledge Graph using Wikibase, the same software that is running behind Wikidata (one of the most successful public Knowledge Graphs). In this talk we describe:
– the content of the EU Knowledge Graph
– why and how it is reusing Wikibase and software that is integrated with it (like OpenRefine)
– how data is ingested and maintained fresh
– what services are served over this Knowledge Graph

It is generally difficult to see a production Knowledge Graph. In this talk we will show you its main components and describe how it is operated behind the scene.

This presentation will be given together with Max De Wilde, information architect at DG CNECT, European Commission.
