Wikidata
Wikipedia's structured-data sibling — a free knowledge graph queried via SPARQL, widely cited by LLMs.
Definition
Wikidata is the structured counterpart to Wikipedia: every item has a Q-number, typed properties, and multilingual labels. It is queryable via SPARQL and is one of the heaviest-weighted sources LLMs draw on for factual entity attributes. Getting a verified Wikidata item is a quiet but effective lever for entity recognition in AI answers.
