EU Knowledge Graph
The EU Knowledge Graph is a Wikibase-based knowledge graph of structured information about the European Union, deployed and maintained at the European Commission. It describes EU institutions, countries and their capitals, and Commission Directorates-General, and it carries the large project datasets that are its main content, namely 2,111,428 projects financed by the European Union recorded through the Kohesio cohesion policy project, and 678,448 beneficiaries of those projects, roughly ten percent of which are linked to Wikidata so that Wikidata statements complement the Commission's own data. It also holds the 2021 Nomenclature of Territorial Units for Statistics (NUTS 2021) used by Eurostat, the multilingual European Science Vocabulary (EuroSciVoc) representing fields of science, and even Commission facilities such as buildings, canteens, cafeterias, and parkings. When queried on 2026-08-06 the query service reported 889,454,967 triples. The stated goal is to make EU project spending visible and navigable for citizens with no technical background; Kohesio is the main public application built on the graph. Because it runs on Wikibase, the graph supports multilingual labels, statement-level provenance, and curation by authorized editors, who sign in through EU Login and request editor rights.
