Quick Start with DuckDB

No download needed — query directly from Hugging Face:

-- Find all "instance of" (P31) values for Q42 (Douglas Adams)
SELECT s.subject, p.label AS property, i.label AS value
FROM 'hf://datasets/RichardDelome/wikidata_truthy/statements.parquet' s
JOIN 'hf://datasets/RichardDelome/wikidata_truthy/properties.parquet' p ON p.pid = s.property
JOIN 'hf://datasets/RichardDelome/wikidata_truthy/items.parquet' i ON i.qid = s.object_id
WHERE s.subject = 42 AND s.property = 31;

-- Look up an entity by name
SELECT qid, label
FROM 'hf://datasets/RichardDelome/wikidata_truthy/items.parquet'
WHERE label = 'Douglas Adams';

-- All items that are "instance of" "human" (Q5) born in a specific year
SELECT i.label, s2.object_value AS birth_date
FROM 'hf://datasets/RichardDelome/wikidata_truthy/statements.parquet' s1
JOIN 'hf://datasets/RichardDelome/wikidata_truthy/statements.parquet' s2
  ON s2.subject = s1.subject AND s2.property = 569  -- P569 = date of birth
JOIN 'hf://datasets/RichardDelome/wikidata_truthy/items.parquet' i
  ON i.qid = s1.subject
WHERE s1.property = 31 AND s1.object_id = 5  -- P31 = instance of, Q5 = human
  AND s2.object_value LIKE '+1952%'
LIMIT 20;
