Thanks.
I only plan on using a query to extract from all english wikidata "articles" or all articles though anyway, hopefully the other queries will work.

Hi!
*The first one, which seems to be only for 1 record, just as a test seemed to give me an ERROR though:*

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.
