I found this following code snippet on opendata.stackexchange.com, which returns name and description of citizens of the US from Wikidata:
prefix wdt: <http://www.wikidata.org/prop/direct/>
prefix wd: <http://www.wikidata.org/entity/>
PREFIX wikibase: <http://wikiba.se/ontology#>
SELECT ?Name ?itemDescription WHERE {
?item wdt:P27 wd:Q30 .
?item rdfs:label ?Name
SERVICE wikibase:label {
bd:serviceParam wikibase:language "en" .
}
}
LIMIT 3
The query can be evaluated at https://query.wikidata.org/
I am trying to get a description of a particular entity, for example Q3(life). But it in this case, the labelService does not return anything.
prefix wdt: <http://www.wikidata.org/prop/direct/>
prefix wd: <http://www.wikidata.org/entity/>
PREFIX wikibase: <http://wikiba.se/ontology#>
SELECT ?Name ?itemDescription WHERE {
wd:Q3 rdfs:label ?Name
SERVICE wikibase:label { bd:serviceParam wikibase:language "en" }
}
LIMIT 3
EDIT: I am using Virtuoso and therefore cannot rely on Wikidata Label Service.
I am using
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX schema: <http://schema.org/>
SELECT ?o
WHERE
{
wd:Q3 schema:description ?o.
FILTER ( lang(?o) = "en" )
}
now, since I am querying a Virtuoso Server with Full-Text-Search capabilities, and it would be better to retrieve the description with other properties in one go.
