As I see there is a tool for detect distance differences :

*OpenStreetMap - Wikidata Validator*
Each circle is an OpenStreetMap feature with a Wikidata tag.
Circle size and color are based on the distance in kilometers between
OpenStreetMap feature and Wikidata coordinates.
Large red circles mean the distance is greater than 10 kilometers, which
indicates a higher error rate.
