Unigraph is a large, open knowledge graph that combines information from knowledge bases such as Wikidata and Freebase with information published by the European Union and national authorities such as the UK's Companies House and US Securities and Exchange Commission. The list of its sources is constantly growing.
The unified data can be downloaded free of charge, for anyone to explore.
Unigraph, which took 3rd place in the EU Datathon 2017, offers a powerful API stack with many options for querying and extracting information, including real-time data streaming. This API provides the easiest and most efficient way to query large amounts of connected data. Many data points in Unigraph push virtually infinite data (on the climate or on trading, for instance). The system stores and retrieves these data efficiently.
The Unigraph engine is available in English.
