Issue with Wikidata Knowledge Base in INCEpTION

[Milica Ikonić Nešić]

Dear Community, 

Thank you for existing above all! 

I have been using the INCEpTION tool for a very long time and it has been extremely useful! At the moment, I am facing a problem: since noon, text connected to the Wikidata knowledge base shows an Error and returns the following message:

Unable to list root concepts: Please set a user-agent and respect our robot policy https://w.wiki/4wJS. See also T400119.

while running the query:

SELECT DISTINCT ?m ?dc ?dp ?subj WHERE { { { { VALUES ( ?subj ) { (<http://www.wikidata.org/entity/Q35120>) } } FILTER EXISTS { { ?subj <http://www.wikidata.org/prop/direct/P31> <http://www.wikidata.org/entity/Q35120> . } UNION { [] <http://www.wikidata.org/prop/direct/P279> ?subj . } UNION { ?subj <http://www.wikidata.org/prop/direct/P279> [] . } } } } OPTIONAL { ?pMatch <http://www.w3.org/2000/01/rdf-schema#subPropertyOf>* <http://www.w3.org/2000/01/rdf-schema#label> . } OPTIONAL { { ?subj ?pMatch ?m . FILTER ( ( LANGMATCHES( LANG( ?m ), "en" ) || LANG( ?m ) = "" ) ) } } OPTIONAL { { ?subj <http://www.w3.org/2000/01/rdf-schema#comment> ?dc . FILTER ( ( LANGMATCHES( LANG( ?dc ), "en" ) || LANG( ?dc ) = "" ) ) } } OPTIONAL { { ?subj <http://www.w3.org/2002/07/owl#deprecated> ?dp . FILTER ( ( LANGMATCHES( LANG( ?dp ), "en" ) || LANG( ?dp ) = "" ) ) } } } LIMIT 2000

Could anyone please help me resolve this problem?

Best regards,

Milica

Hi,

I saw some post related to a change on the Wikidata mailing list, but
I didn't fully check it yet... I'll have a closer look at what new
requirements they have now and get back to you.

That said: the obvious way around those query limitations is that you
download the Wikidata dumps and set up your own SPARQL endpoint with
those and use that one instead of using the official Wikidata SPARQL
endpoint.

Cheers,

-- Richard

I have just released INCEpTION 37.5 which should restore the ability to talk to
the WikiData SPARQL endpoint.

Hi Richard, 

I used to see the description from Wikidata when I hovered over the linked entity, but now I don’t see it. How can I enable this again? 

Thanks in advance!  

Best regards,

Milica

Check if a description is shown under the concept input field in the right sidebar.

When a description is shown there, I also get it in the hover popup when using WikiData.

No, It’s not showing for me, although it used to.

Try annotating something with "Obama" (http://www.wikidata.org/entity/Q11462618) - that shows a description for me.

If that description does not show, try creating a new entity linking project and check if it works for you there.
If it does, check if you changed anything in the knowledge base sesttings in your old project, in particular
in the mapping part where all the IRIs are set.
