Fetch data using SPARQL

LinguaLibre data can be fetched using various coding languages such as Python, Javascript, R and others, returning JSON or other formats.

  • For code snippet in your language : open query.wikidata.org (WikiData Query Service, aka WDQS), run your SPARQL query, click "Code" : a pop up window appears with various implementations.
  • For downloading data, click "Download".

Javascript:
At least 3 methods exists (code snippet), example:

Query Result's basic unit
SPARQL:
SELECT ?item WHERE { ?item prop:P2 entity:Q5 } LIMIT 10

{ … },
{
  "item": {
    "type": "uri",
    "value": "https://lingualibre.org/entity/Q12"
  },
  "itemLabel": {
    "xml:lang": "en",
    "type": "literal",
    "value": "beginner"
  }
},
{ … }
Javascript: 
var endpoint = 'https://lingualibre.org/sparql';
var sparql = 'SELECT ?item WHERE { ?item prop:P2 entity:Q5 } LIMIT 10';
$.getJSON(endpoint,
	{ query: sparql, format: 'json' },
	function(data){ console.log('JQuery: ',data)}
);

Audio Qid → Audio data

Langue + speaker + word → Audio's Commons url

Heavy queries

❌ Is Language (speaker (Q3)) → list all languages with number of unique words and speakers

Too large to run (not even on Lingualibre Query). 

SELECT ?language (COUNT(?audio) AS ?nbAudio) (COUNT(?speaker) AS ?nbSpeaker) WHERE {
  ?language prop:P2 entity:Q4 .
  ?audio prop:P4 ?language .
  ?speaker prop:P4 ?language .
}
GROUP BY ?language

To do: do smaller sub-queries. For now, works only for one counter and one language at a time:

❌ Languages → Name, Wikidata Qid, LLQid, Iso-639-3, and genders

Query Result 
SELECT ?languageQidLabel ?wdQid ?languageQid ?isoCode 
(COUNT(DISTINCT(?record)) AS ?recordCount)
(COUNT(DISTINCT(?speakerLangM)) AS ?speakerM) 
(COUNT(DISTINCT(?speakerLangF)) AS ?speakerF)
wWHERE{
  ?record prop:P2 entity:Q2 .     # Filter: items where P2 'instance of' is Q2 'record'
  ?record prop:P4 ?languageQid .  # Assign value: P4 'language' into variable ?language
  ?languageQid prop:P12 ?wdQid .  # Assign value: P12 'wikidata id' into variable ?WD
  ?languageQid prop:P13 ?isoCode. # Assign value: P13 'iso639-3' into ?isoCode
  
  #?record prop:P5 ?speakerQidM .   # Assign value: P5 'speaker' into variable ?speakerQidM
  #?speakerQidM prop:P8 entity:Q16 .   # Filter: P8 'sex or gender' is Q16 'male
  #?speakerQidM prop:P4 ?speakerLangM .  # Assign value: P4 'language' into variable ?spakerLangM
  
  ?record prop:P5 ?speakerQidF .   # Assign value: P5 'speaker' into variable ?speakerQidF
  ?speakerQidF prop:P8 entity:Q17 .   # Filter: P8 'sex or gender' is Q17 'female
  ?speakerQidF prop:P4 ?speakerLangF .  # Assign value: P4 'language' into variable ?spakerLangF
  
  SERVICE wikibase:label { bd:serviceParam wikibase:language "en" . } 
}
GROUP BY ?languageQidLabel ?languageQid ?wdQid ?isoCode
ORDER BY DESC(?recordCount)
