Hi!
I'm wondering if there is a way (SQL, api, tool or otherwise) for finding out how often a particular source is used on Wikidata.
Something like this probably would work:
This runs the following query:
prefix prov: http://www.w3.org/ns/prov# prefix pr: http://www.wikidata.org/prop/reference/ PREFIX wd: http://www.wikidata.org/entity/ SELECT (count(?ref) as ?mentions) WHERE { ?statement prov:wasDerivedFrom ?ref . ?ref pr:P248 wd:Q216047 . ?ref pr:P577 ?date . }
For Q216047 which is "Le Figaro". This counts how many statements reference Le Figaro and also have dates (drop the last clause if non-dated ones are fine too).
