Fetch SPARQL data

Data can be fetched using various coding languages such as Python, Javascript, R and others. On the Wikidata Query Service page, after running your SPARQL query, click "Code" : a pop up window appears with various implementations.

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

Query Result 
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)}
);

{
      "item" : {
        "type" : "uri",
        "value" : "https://lingualibre.org/entity/Q12"
      },
      "itemLabel" : {
        "xml:lang" : "en",
        "type" : "literal",
        "value" : "beginner"
      }
    }

✅ Is Sex or Gender(sex or gender (Q7)) → list all possible values

SELECT ?item ?itemLabel
WHERE {
  ?item prop:P2 entity:Q5    # Condition 1, P2 'instance of' is Q5 'language level'.
  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
  } 
}
... Loading ...

✅ Is Speaker (speaker (Q3)) → list all speakers

SELECT ?speaker ?speakerLabel
WHERE {
  ?speaker prop:P2 entity:Q3 .  # Condition 1, P2 'instance of' is Q3 'speaker'.
  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
  } 
}
... Loading ...

✅ Speaker name(s) → Speaker Qid(s)

SELECT ?speakerName ?speakerId
WHERE {
  VALUES ?speakerName { "Yug" "VIGNERON" } # One or multiple values
  BIND ( STRLANG(?speakerName, "en") AS ?speakerLabel )
  # P2: instance of; Q3: speaker.
  ?speakerId prop:P2 entity:Q3 ; rdfs:label ?speakerLabel .
}
... Loading ...

✅🇶 Speaker Qid: 0x010C (Q42) → Speaker data

# Get Q42 (User:0x010C)'s data
SELECT ?predicate ?predicate ?object ?objectLabel
WHERE {
  entity:Q42 ?predicate ?object .
  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
  } 
}
... Loading ...

✅🇶 Speaker Qid: 0x010C (Q42) → Speaker data → Speaker languages P4

SELECT ?languages ?languagesLabel
WHERE {
  entity:Q42 prop:P4 ?languages .
  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
  } 
}
... Loading ...

✅ Speaker Qid + language → list of all associated audios

SELECT ?audio ?audioLabel
WHERE {
  ?audio prop:P5 entity:Q42 .   # Condition 1, P5 Speaker is Q42 User:0x010C
  ?audio prop:P4 entity:Q21 .   # Condition 2, P4 language is Q21 French
  # Labels
  SERVICE wikibase:label {
    bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
  } 
}
... Loading ...

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

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

Too large to work :(

Isolang → Language LL Qid

SELECT * WHERE {
  ?lang prop:P13 ?code .
}
... Loading ...

Isolang → Language WD Qid

SELECT * WHERE {
  ?lang prop:P12 ?idWikidata .
}
... Loading ...

Language WD Qid → Language data

SELECT * WHERE {
  ?lang prop:P12 "Q12107" .
  ?lang ?predicate ?object .
}
... Loading ...

Language LL Qid → Language data

SELECT * WHERE {
  entity:Q209 ?predicate ?object .
}
... Loading ...

Langue + speaker + word → Audio's Qid

SELECT ?audio
WHERE {
  ?audio prop:P4 entity:Q209 . #language
  ?audio prop:P5 entity:Q584098 . #speaker
  ?audio rdfs:label ?word . #word
  FILTER ( STR(?word) = "ni" )
}
... Loading ...

Audio Qid → Audio data

✅ Langue + speaker + word → Audio's Commons url
