The Artificial Knowledge Collection becomes a collection: the founding common-sense map plus nine more human-authored or human-measured datasets, and one merged file that ties them all together.
⭐ Top download — the What Exists List
What-Exists-List.jsonl.gz is the merged master file: 544,279 things that exist — concepts, word senses, words, elements, isotopes, stars, planets, countries, cities, foods, physical constants, everyday things — in one unified schema, connected by 1,003,336 associations. One aligned relation vocabulary lets a single chain cross from the hand-built ontology into WordNet into the everyday-assertion graph without a translation table; a 31,008-link bridge joins the concept map to WordNet directly. Start with What-Exists-List.sample.jsonl (readable) and What-Exists-List.manifest.json (counts).
