Wikidata Query Service traverse property

Question

I am trying to get a list of all hyperonymes of a given Wikidata item. For instance I want to traverse the "subclass of" element for https://www.wikidata.org/wiki/Q4421.

How would the SPARQL command for https://query.wikidata.org look like?

Answer 1

You can use the property path (*) syntax.

In this case wdt:P279* to mention 0 or more time wdt:P279 which is subclass of equivalent in Wikidata model.

I added a few variation here to include the depth so you can order them

SELECT ?entity ?entityLabel (count(?mid) as ?depth) WHERE {
  wd:Q4421 wdt:P279* ?mid.
  ?mid wdt:P279* ?entity
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
} group by ?entity ?entityLabel
order by ?depth
