Quering items with no labels on a specific languageHey, folks. I want to query items that has no labels (as well as no description, and also maybe both of them at the same time) of a language, but I can't seem to figure out how to do it. Say that I have this query.

Use at

PREFIX wdt: <http://www.wikidata.org/prop/direct/>
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX ps: <http://www.wikidata.org/prop/statement/>
PREFIX p: <http://www.wikidata.org/prop/>
SELECT ?item ?point_in_time WHERE {
  {
    SELECT DISTINCT ?item WHERE {
      ?item p:P31 ?statement0.
      ?statement0 ps:P31 wd:Q47150325.
    }
  }
  OPTIONAL { ?item wdt:P585 ?point_in_time. }
}
LIMIT 100
