Dear Mr.,
I thank you for the query. This is absolutely useful to ameliorate data mining methods for Wikidata. I always said that Wikidata Query Service is still misused.
Yours Sincerely,

Objet : Re: [Wikidata] Full-text / autocomplete search on labels

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 that looks for "human (Q5)"  whose label contains the string "einst".

Hope this helps,

Ettore Rizza

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
