wikidata5m_kg.tar.gz

This is the processed knowledge graph used in our experiments. It contains:

• 4,665,331 entities
• 810 relations
• 20,987,217 triples

After extraction, it yields a single file: wikidata5m_kg.jsonl, each line is a JSON object representing an entity with its metadata and one-hop neighborhood. Example:

{
  "entity_id": "Q10417481",                          // Unique entity ID
  "entity_description": "Arethaea polingi, or Poling's thread-legged katydid, is a species of phaneropterine katydid in the family Tettigoniidae. It is found in North America.",       // Description of an entity
  "entity_alias": ["Arethaea polingi", "arethaea polingi"],  // Aliases of an entity
  "all_one_hop_triples_str": [                       // One-hop outgoing triples (relation, tail entity)
    ["parent taxon", "Arethaea"],
    ["instance of", "Taxxon"],
    ["taxon rank", "cohesion species"]
  ]
}
