Ground truth for correct facts could be: 1) Wikidata 2) Mathematical ground truth (can be both generated and results validated automatically) including physics 3) Programming ground truth (can be validated by running the code and defining inputs/outputs) 4) Chess 5) Human labelled images and video 6) Map data 7) Dependent on your viewpoint, peer reviewed journals, as long as cited with sources.
