SPARQL (intermediate)


Help:SPARQL 2 will explore federated queries fetching data from both LinguaguaLibre and Wikidata's endpoints, then Wikidata Lexemes, an emerging source of lexicographic data. The duo can be a solid combo to provide lexicographic and multimedia (audio recordings and images) for either Wikimedia modules or web developers.

SPARQL to persitent data

Some SPARQL queries are meaningful but heavy and overly slow. This administrator tool stores or updates the response data on LinguaLibre, within a wikipage. Stored data can then be loaded in <0.1 second. Multiple data can also be merged via a common property if any.


Federated queries

  • To query Lingualibre from Wikidata, use SERVICE <https://lingualibre.org/sparql>.
  • To query Wikidata from LinguaLibre, use SERVICE <https://query.wikidata.org/sparql>.

Retrieve data of LinguaLibre from Wikidata

The following query shows a simple example of retrieving data of LinguaLibre from Wikidata Query Service. It lists the existing levels in LinguaLibre. 

PREFIX prop: <https://lingualibre.org/prop/direct/>
PREFIX entity: <https://lingualibre.org/entity/>

SELECT * {
  SERVICE <https://lingualibre.org/sparql> {
    SELECT
      ?item
      ?itemLabel
    {
      ?item prop:P2 entity:Q5.
      SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
    }
  }
}

Number of audios per each dead and extinct languages that exist in LinguaLibre

It obtains the list of dead and extinct languages from Wikidata. This query is expected to be run in Lingua Libre SPARQL endpoint. It shouldn't be run in the SPARQL endpoint of Wikidata or Wikidata Query Service. 

SELECT
  ?deadLanguageLinguaLibre
  ?deadLanguageLinguaLibreLabel
  ?count
WITH {
  SELECT DISTINCT ?deadLanguage {
    SERVICE <https://query.wikidata.org/sparql> {
      { ?deadLanguage wdt:P31/wdt:P279* wd:Q45762. }
      UNION
      { ?deadLanguage wdt:P31/wdt:P279* wd:Q38058796. }
    }
  }
} AS %deadLanguage
WITH {
  SELECT ?deadLanguageLinguaLibre {
    INCLUDE %deadLanguage.

    BIND(REPLACE(STR(?deadLanguage), '.*/', '') AS ?deadLanguageQid)

    ?deadLanguageLinguaLibre
      prop:P2 entity:Q4;
      prop:P12 ?deadLanguageQid.
  }
} AS %deadLanguageLinguaLibre
WITH {
  SELECT
    ?deadLanguageLinguaLibre
    (COUNT(*) AS ?count)

      prop:P4 ?deadLanguageLinguaLibre.
  }
  GROUP BY ?deadLanguageLinguaLibre
} AS %count
{

  OPTIONAL{INCLUDE %count.}
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
}
ORDER BY DESC(?count)
