I wanna know if there is an algorithm for comparing DBpedia-Live facts with wikipedia facts, relative to a given ressource (example: http://live.dbpedia.org/page/Cristiano_Ronaldo ) for a ratio as a result (number of the matched facts between DBpedia-Live and wikipedia/total number of facts represented on DBpedia-live)
It will query the Wikipedia page and do the extraction. Then you can compare it.
Otherwise you could write SHACL tests and run them via the latest monthly release or main endpoint and compare with SHACL over live.
