rq turtle/ttl

The query takes 40 to 50 seconds to run which seems far too much to find a single item. With this little rewrite with a string constant instead of ?title_sv:

Use at

PREFIX schema: <http://schema.org/>
SELECT ?article_sv ?item
WHERE 
{
  ?article_sv schema:name "Helsingfors"@sv.
  ?article_sv schema:isPartOf <https://sv.wikipedia.org/>.
  ?article_sv schema:about ?item.
}
