YAGO 4.5 is the latest version of the YAGO knowledge base. It is based on Wikidata — the largest public general-purpose knowledge base. YAGO refines the data as follows:

  1. All entity identifiers and property identifiers are human-readable.
  2. The top-level classes come from schema.org — a standard repertoire of classes and properties maintained by Google and others. The lower level classes are a careful selection of the Wikidata taxonomy.
  3. The properties come from schema.org.
  4. YAGO 4.5 contains semantic constraints in the form of SHACL. These constraints keep the data clean, and allow for logical reasoning on YAGO.

YAGO is thus a simplified, cleaned, and “reasonable” version of Wikidata. It contains 49 million entities and 109 million facts.
