✅ Is Sex or Gender(sex or gender (Q7)) → list all possible values
SELECT ?item ?itemLabel
WHERE {
# P2: instance of; P9: subclass of; Q7: gender or sex.
?item prop:P2/prop:P9 * entity:Q7
SERVICE wikibase:label {
bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
}
}
|
|
✅ Is Speaker (speaker (Q3)) → list all speakers
select ?speaker ?speakerLabel
where {
?speaker prop:P2 entity:Q3 .
SERVICE wikibase:label {
bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" .
}
}
|
|
Speaker name → Speaker Qid
select ?speakerName ?speakerId
where {
VALUES ?speakerName { "Yug" "VIGNERON" } #One or multiple values are acceptable here
BIND ( STRLANG(?speakerName, "en") AS ?speakerLabel )
?speakerId prop:P2 entity:Q3 ; rdfs:label ?speakerLabel .
}
|
|
Speaker Qid (0x010C (Q42)) → Speaker data
SELECT ?predicate ?object
WHERE {
entity:Q42 ?predicate ?object .
}
|
|
Speaker Qid → Speaker data → speaker languages
SELECT ?languages
WHERE {
entity:Q42 prop:P4 ?languages .
}
|
|
Speaker Qid + language → list of all associated audios
SELECT ?audio WHERE {
?audio prop:P5 entity:Q42 .
?audio prop:P4 entity:Q21 .
}
|
|
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 .
}
|
|
Isolang → Language WD Qid
SELECT * WHERE {
?lang prop:P12 ?idWikidata .
}
|
|
Language WD Qid → Language data
SELECT * WHERE {
?lang prop:P12 "Q12107" .
?lang ?predicate ?object .
}
|
|
Language LL Qid → Language data
SELECT * WHERE {
entity:Q209 ?predicate ?object .
}
|
|
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" )
}
|
