To prevent hallucinations, I strictly use Wikipedia/Wikidata as a structural ‘skeleton’—only pulling objective metadata like titles, years, and URLs. This anchors the AI to a source of truth rather than relying on generative text.
For dense categories, I filter by translation count to surface globally significant events. On top of that, I personally spot-check the data manually after every batch.
That said, bias is tricky. This map ultimately reflects who documented their history well, rather than just ‘what happened.’ Regions with strong written traditions appear denser because their records were preserved and translated. It’s a visualization of recorded history, with all the inherent survivorship bias that comes with it.
