Jheald added a comment to T238340: Import UK lakes in Wikidata.

@Pintoch That's great. I'' try and get matching these this weekend. Is there any chance of the full dataset, beyond the first 1000? We currently have 1660 items for bodies of water in the UK (plus more that possibly don't have P31s), so it would be nice to be able to try to match them all. But thanks again for this!

Jheald added a comment to T238751: Only generate maxlag from pooled query service servers..

If maxlag is to be based on the maximum lag of the pooled servers, will there be active measures to monitor these, and take any really badly lagged server (ie significantly worse lagged than any of the others) out of the pool, and out of the maxlag calculation, to give it a chance to recover ?

One thing that seems odd (to an outsider like me who knows very little about the system) is that some servers seem to be performing so much worse than others.

Jheald updated subscribers of T230314: Show constraint violations on SDC statements.

@Lucas_Werkmeister_WMDE How dependent is the wikibase constraint system on SPARQL ?
Maarten was just suggesting that a functioning SPARQL service is required for any of the constraint checking to operate (and so this ticket would be completely blocked until CDQS is reliably up and running)
Is that correct? Or are any of the simplest of the constraint checks (eg format constraints, one-of constraints, etc) available without SPARQL ?

There is some sense in what MisterSynergy says, but I also think there is sense in what @deryckchan wrote in the RfC (here), namely that there still ought to be some warning if someone tries to sitelink to a redirect page, and the user should be made to actively confirm that they didn't want to instead link to the redirect target. Otherwise I could see us ending up with a lot of accidental sitelinks to mis-spellings, which the present system mostly keeps us safe from.

Jheald added a comment to T235420: Create wikidata badges to indicate when sitelinks point to Wikipedia redirect pages.

Mostly, the existence of a sitelink to a redirect indicates a potential data problem on Wikidata: a sitelink that has been left over when two Wikipedia articles have been merged, but no corresponding merge has been made on Wikidata. A sitelink to a redirect can therefore be a strong indication that an item on Wikidata is a duplicate of another one, and should be merged with it. However, at the moment it is not possible for somebody browsing a Wikidata article to readily spot that a sitelink points to a redirect. A badge to identify this would bring the fact into plain sight.

On a separate but related issue: we now have quite a lot of images of old maps on Commons, with coordinate georeferencing allowing the maps to be "warped" to standard coordinate systems. It would be nice to be able to serve the warped versions of the maps as tilesets, allowing users to compare different historical representations of given places as layers.

The aim was to try to identify the different generic stages of the workflow in machine vision, and to think how each stage could be made as "pluggable" as possible, so how users could be made able to plug in their own approach at any stage, and report their results from that stage back into the overall pipeline.

Jheald updated subscribers of T228770: Design a system for serving images with depicts suggestions needing confirmation.

So for example this afternoon @Miriam is going to be leading a workshop session introducing image classifiers and clustering algorithms, with a view that Commons users can start to explore writing their own large-scale machine-learning image analysis tools. It would be good if there was syntax in place so they could write the results of those explorations to Commons SDC, for that they were there and accessible for the community to then refine or extract or take further for each image. Similarly two days ago @Multichill led a small group session, to try to think through what was the generic pipeline and workflow for machine-learning contributions, and what kind of open framework was needed to support bulk contributions of that kind from allcomers and any set or subset of images. @Fuzheado too has been talking about some of the investigations he has been doing with machine vision and the Metropolitan Museum collection. All those voices, and more, I think would have useful input for this conversation.

Agree with @alaa_wmde that no requirement's yet been made out for having structured data on EntitySchemas within Wikidata. But it would be useful to have the EntitySchemas themselves (not surrogate items for them) represented in WDQS, so that they can be queried. That is the subject of ticket T225701 "Add EntitySchemas to the Query Service". A federated service, rather than putting them in the main WDQS triplestore, would probably satisfy this.

As a postscript to my comment two posts above, note that in such a scenario a Commons category page might well be associated with both an item on Wikidata (via a sitelink equivalence) and a local item on the Commons wikibase.

In the context of this thread, it's worth recalling the ongoing wish from Commons users for Commons categories to be able to have their own local items on the Commons wikibase.

Hi @JeanFred . The point is not so much to link multiple versions of the same viewer, but rather to link to some of the different viewers available, for example here is the Alba Madonna in the "Universal Viewer" used as a default by the Wellcome Collection and the British Library and others.

To support what Smalyshev said: occasional termporary update lag may not be such a high-priority issue; but prolonged or repeated update lag rapidly would be.

Jheald added a comment to T187872: Support IIIF Image API for thumbnailing & tiling of images.

(Copied from T173346)
I'd like to note strong interest on two different occasions from two different people in the last month in a top-tier GLAM that I'm working with, about the possibility of being able to use Commons as an IIIF hosting service for high-resolution images, eg for serving tiles of old maps for geo-referencing to platforms that need to be able to access images from an IIIF service.

Jheald added a comment to T194401: Investigate storing commons data in BlazeGraph.

Presumably (as the original ticket suggests), one option would be to set up a Commons Data Query Service (CDQS) as a distinct endpoint on a new server that had both Wikidata and CommonsData installed in a Blazegraph instance locally. This would allow the existing WDQS service to continue without alteration, while allowing the CDQS service set-up to be optimised, as we learn more about the sort of queries that people want to run.

The 400 character limit can also be a problem for the titles of old books, maps, etc -- the original titles of these, as given eg in library catalogues, can get pretty long.

Jheald added a comment to T191633: Implement searching of 'depicts' on commons.

Interesting slide-show. But the fundamental problem -- as some of the attached tickets start to appreciate -- is that the key information that determines whether an image fits the specification being looked for is not going to be stored in statements just on the CommonsData item for the image in question, nor just on the Wikidata item for the thing it depicts, but is going to depend on statements distributed throughout the database.

Well of course you're going to copy all the CommonsData statements to Blazegraph.

I have now found T198261 and T199119, which investigate how some of the drawbacks above with the simple string-matching approach might be addressed.

Jheald added a comment to T199119: Research relationships between items in wikidata.

I'd say don't give up too easily. This is probably as good an approach as any. If the issues are structural, bots will fall prey to them in just the same way, just more slowly and more haphazardly.

Jheald added a comment to T191633: Implement searching of 'depicts' on commons.

The attached subtickets are an interesting read. They all seem to be based on taking the Q-number value of "depicts", storing it as a string in the text-search index, and then doing an indexed string-match for it. Of course first baby-steps are important, and this facility will be crucial to be able to confirm correct entry, storage, and direct retrievability of "depicts" values.

Jheald added a comment to T181062: Adapt QuickStatements2 to be able to work with structured data on Commons as well.

One sidelight on this. QS2 is great (invaluable!) for adding new statements, but not so good for modifying existing statements, especially if they are currently heavily qualified or referenced -- at the moment, the entire statement complete with all qualifiers and references has to be re-created, even if one only wants to change one qualifier value, or migrate the property being used for the qualifier.
