Re: work on analyzing or improving the Wikidata ontology

The inferencing that goes on in Wikidata is, as far as I know, done by "bots" 
- external programs that look over information in Wikidata and add in some 
simple consequences of that information.   The most active of these bots is 
KrBot, which uses information in Wikidata talk pages.  See
https://commons.wikimedia.org/wiki/File:DMD2023_-_A_better_way_to_enforce_a_data_model._Suggestions_to_improve_Autofix.pdf 
for a recent presentation on some of the problems with this methodology.

I would very much like to see a better method for performing inference in 
Wikidata, or at least discovering violations of the constraints implied by the 
intended meaning of central Wikidata entities.

As far as I know there is little direct use of Wikidata in old-fashioned AI.

My current work with the Wikidata ontology is investigating and fixing 
problems with the building blocks of the ontology, including disjointness 
violations and violations of class orders.  But I'm very interested in coming 
up with a good way of automatically performing inference and constraint 
checking in Wikidata.
