Hello I understand the wikidata SPARQL label service only fetches the labels, but does not allow to search/filter on them; labels are also available in regulare rdfs:label on which a FILTER can be made. However I would like to do full-text search over labels, to e.g. feed an autocomplete search field, actually just like the usual top-right wikidata search field does. I would also be interested to combine this with a criteria on "instance of", to search only on instances of a given class. Can I do that efficiently using the Wikidata SPARQL service ? or is there a separate API I could use ? (exemple welcome) Thanks Thomas -- *Thomas Francart* -* SPARNA* Web de *données* | Architecture de l'*information* | Accès aux *connaissances* blog : blog.sparna.fr, site : sparna.fr, linkedin : fr.linkedin.com/in/thomasfrancart tel : +33 (0)6.71.11.25.97, skype : francartthomas _______________________________________________ Wikidata mailing list Wikidata(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata

Hello Thomas, You can perform a full text search with the API, but not yet with SPARQL AFAIK. However, it is possible to call the API in a SPARQL query. For example, here is a query <https://query.wikidata.org/#SELECT%20DISTINCT%20%3Fperson%20%3FpersonLabel%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Amwapi%20%7B%0A%20%20%20%20%20%20bd%3AserviceParam%20wikibase%3Aapi%20%22EntitySearch%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20wikibase%3Aendpoint%20%22www.wikidata.org%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20mwapi%3Asearch%20%22einst%22%20.%0A%20%20%20%20%20%20bd%3AserviceParam%20mwapi%3Alanguage%20%22en%22%20.%0A%20%20%20%20%20%20%3Fperson%20wikibase%3AapiOutputItem%20mwapi%3Aitem%20.%0A%20%20%7D%0A%20%20%3Fperson%20wdt%3AP31%20wd%3AQ5.%0A%20%20%0A%20%20%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%0A%20%20%0A%7D%20ORDER%20BY%20DESC(%3Fperson)%20LIMIT%2020> that looks for "human (Q5)" whose label contains the string "einst".

Forgot to mention: you can do the same search using the API only: https://www.wikidata.org/w/api.php?action=wbsearchentities&search=einst… But not sure you can easily filter the results by "instance of".
