Aktienführer Knowledge Graph

The Aktienführer (AKF) Knowledge Graph is free and open. It contains structured (meta)data for the German listed stock companies from the Hoppenstedt-Aktienführer from 1956 to 2018. The metadata includes official company names with time ranges, company identifiers (ISIN and WKN) and Aktienführer IDs.

We enriched metadata via entity linking with other databases: Creditreform, Bureau van Dijk Orbis, GND and Wikidata. The knowledge graph contains 342 external identifiers representing various databases.

The AKF (meta)data is accessible by both humans and machines.
