I have written the following query to find the languages that have a label in Tunisian in Wikidata: SELECT ?_tre_humain ?_tre_humainLabel WHERE { SERVICE wikibase:label { bd:serviceParam wikibase:language "aeb-arab". } ?_tre_humain wdt:P31 wd:Q34770. } However, I found that many languages not having a label in Tunisian are sorted as well. For these languages, the featured label is the Wikidata ID of the language. I ask about how to eliminate these languages from the results of my wikidata query.

Hi Iván, You provided an explanation, where I only gave the updated query. There's one difference between our queries: I removed the service line because that doesn't add anything in this case. Since you only use it to fetch the label and you're already doing that with rdfs:label. If you needed labels for other claims or needed descriptions, than the adding the service line would still be useful. Mbch331 Op 4-3-2018 om 22:33 schreef Iván Hernández Cazorla:

Hi Iván, I need to learn a lot too about SPARQL. The best way to learn is by doing it. And if you don't succeed, Google it or ask for others to help. Mbch331 Op 12-3-2018 om 19:23 schreef Iván Hernández Cazorla:

I modified your query with the filter, check it: SELECT ?_tre_humain ?_tre_humainLabel WHERE { ?_tre_humain wdt:P31 wd:Q34770. ?_tre_humain rdfs:label ?itemLabelAebArab . FILTER(lang(?itemLabelAebArab) = "aeb-arab") SERVICE wikibase:label { bd:serviceParam wikibase:language "aeb-arab". } } You can test it [0]. To explain the query now, what I added is: ?_tre_humain rdfs:label ?itemLabelAebArab . FILTER(lang(?itemLabelAebArab)="aeb-arab") The first line query the label with the ?itemLabelAebArab object and the second filter the language. Note that the object (?itemLabelAebArab) must to be in the filter. I hope it helps you.
