Wikidata:SPARQL query service/queries/examples

This page is parsed by the web interface of the query service to fill the query example dialog. Many of the examples also work in template:Wikidata list template calls parsed by the Listerbot, which however requires the ?item field variable to be selected.

Consider adding a comment in the query noting what it illustrates, when and by whom it was written and which are its limitations given the current data and use of properties at Wikidata.

Some queries did not fit here because of technical restrictions:

• Advanced examples which showcase more advanced functionality.
• Human examples which have all kinds of human related queries.
• Maintenance examples which help to curate all our items.

Humans born in New York City

This example highlights the correct way to use the P19 property and by extension the P20 property. P19 is most specific known place of birth. So for example it is known that Donald Trump (Q22686) was born in Jamaica Hospital (Q23497866). Therefore he wouldn't show up in the first query.

Incorrect way:

select distinct ?item ?itemLabel ?itemDescription ?sitelinks where {
    ?item wdt:P31 wd:Q5;  # Any istance of a human.
          wdt:P19 wd:Q60;  #  Who was born in New York City.
# Note. Doesn't include humans with the birth place listed as a hospital
# or an administrative area or other location of New York City.

             wikibase:sitelinks ?sitelinks.
   
    SERVICE wikibase:label { bd:serviceParam wikibase:language "en,nl" }
}
ORDER BY DESC(?sitelinks)

Try it!

Correct way:

Mediawiki API

Filter labels using EntitySearch from mwapi service to provide Full Text Search

See documentation and examples in the MWAPI user manual.

#Combine the Wikidata Query Service and the Mediawiki API
#https://www.mediawiki.org/wiki/Wikidata_Query_Service/User_Manual/MWAPI
#(which is backed by Elasticsearch) to perform very fast searching of entities by their label.
#
#This query will first contact EntitySearch (an alias to wbsearchentities)
#which will pass the items with a label of "soriano" it found to the triple store
#which in turn can now query the graph in a timely manner and filter those entities that are not humans.
#This solution only works if the number of items returned by wbsearchentities remains reasonable.
