The new system, called WiCleanData, fixes this in three stages: a language model cleans up the taxonomy, type constraints get simplified through hierarchical aggregation, and any remaining facts that still break the rules get filtered out. The result is a full knowledge graph, free of type violations, published with a web interface so anyone can browse it or plug it into other projects.\n\nWikidata quietly underpins a lot of things readers never see, from Wikipedia infoboxes to search engine knowledge panels to training data for AI systems. A graph edited by thousands of contributors was always going to drift into inconsistency, and manually auditing millions of entries is not realistic. Using a language model to police the structure of a knowledge base, rather than just answer questions about one, is a notable use of the technology.\n\nWhether WiCleanData stays clean as the live Wikidata keeps changing by the minute is the real test. A tidy snapshot is easy. A permanently tidy graph is a different problem entirely.","[\"wikidata\",\"knowledge-graphs\",\"language-models\",\"data-quality\"]","2026-09-18T04:00:00.000Z","2026-09-18T17:12:39.563Z","2026-09-18T17:12:51.520Z","published",null,[],"ai",[26,27,28,29],"wikidata","knowledge-graphs","language-models","data-quality",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.20057",0,{"sections":36},[37,40,44,49,54,58,62,67,71,76,81,86,91,96],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",4017,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",653,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",338,"2026-09-11T04:00:00.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":18},"Hardware","hardware",155,{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",121,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",99,"2026-09-09T17:27:33.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":18},"Dev Tools","dev-tools",77,{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",75,"2026-09-10T20:41:21.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",55,"2026-09-09T23:14:29.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",43,"2026-09-10T12:18:06.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",41,"2026-09-08T01:57:23.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
