Hi!
*The first one, which seems to be only for 1 record, just as a test seemed to give me an ERROR though:*
PREFIX wd: http://www.wikidata.org/entity/ PREFIX wdt: http://www.wikidata.org/prop/direct/ PREFIX rdfs: http://www.w3.org/2000/01/rdf-schema# PREFIX schema: http://schema.org/
SELECT * WHERE { http://www.wikidata.org/entity/Q1652291 http://schema.org/description ?o . filter(lang(?o)='en').
?article schema:about ?item . ?article schema:inLanguage "en" . FILTER (SUBSTR(str(?article), 1, 25) = "https://en.wikipedia.org/")
}
This one is not correct - ?item should be replaced by http://www.wikidata.org/entity/Q1652291. Or you can use BIND or VALUES syntax in SPARQL to bind all instanced of ?item to one or more specific items. But if you just leave it as ?item it matches any value - which means you just made it scan through all 15M items :) That will time out.
