Dear Mr., I thank you for your efforts. I ask if a tutorial about merging Wikidata API with Wikidata Query Service or about doing federated queries with Wikidata Query Service can be done.

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.

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 queryhttps://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".

Hope this helps,

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
