  Yeah we weren't sure if the underlying problem was in the ontology or our 
query. If it's in the ontology it's not on us. So closing.

[Wikidata-bugs] [Maniphest] T273639: Incorrect results displayed when 'values from subclasses' is checked

  I don't see a problem with our system. It's an issue with the ontology.
  
  For the record. The peramlink is this 

 and the resulting query is this:
  
SELECT DISTINCT ?item WHERE {
  ?item (p:P31/ps:P31/(wdt:P279*)) wd:Q5.
  MINUS { ?item (p:P106/ps:P106/(wdt:P279*)) _:anyValueP106. }
}
LIMIT 10
  
  The first result I got is:
  
  - https://www.wikidata.org/wiki/Q1187884 (continuity announcer) which is 
wrong but:
- It has instance of https://www.wikidata.org/wiki/Q1371925 (announcer) 
which is subclass of https://www.wikidata.org/wiki/Q702269 (professional) which 
is subclass of https://www.wikidata.org/wiki/Q5 (human)
  - The case you mentioned is also similar, it used to have 
https://www.wikidata.org/wiki/Q474968 (anonymous master) which is subclass of 
anonymous which is a subclass of human. You can follow the ladder and find it.
  
  So I don't see a problem here. The ontology is not perfect and needs work, 
that's for sure but we are not responsible neither allowed to do it on behalf 
of the community.
