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.

It would be good for unassessed suggestions for statements (and not necessarily just "depicts" statements) to be accessible via the SPARQL query service, in the same way as regular statements, but possibly set with a lower trust level.

Jheald added a comment to T214884: linking Schemas in statements.

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.

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.

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.

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.

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.

To make this really useful, it would be valuable for a WDQS query to be able to display such shapes in the map view of query results.

Jheald added a comment to T157811: Wikidata reference URIs have become too many to search with WDQS SPARQL.

So you're saying, in effect, I should think of the strings being stored as a great big hash table rather than a B-tree, so there's nothing there that can help even STRSTARTS. And of course I know very little about the internals of BlazeGraph, whereas you've actually written modules for it. But I did think BlazeGraph uses B+ trees, which do specifically facilitate rapid in-order traversal and retrieval. But perhaps only to retrieve hashes, not strings?

Thanks for your speedy diagnosis. I've gone through and reverted and then un-reverted the ten edits by hand, so they are now fine.

Ouch. That sounds quite nasty. The only thing I can think of from the user side that was perhaps slightly different about this set of edits was they were made with QuickStatements while I already had a different QuickStatements run open and going in another window (a big batch of 10,000 corrections in capitalization of item labels, which took about two and a half hours to run, all of which went through fine).

Another case where it could be useful to be able to cast calculated co-ordinates back to a geo:wktLiteral would be to allow AVG() co-ordinates to be calculated and plotted, in cases where SAMPLE() is not sufficient.

Trying to get round this, by just plotting the values in a scatterplot, without a map, also failed -- though that's likely to be an issue with the scatterplot routine. (Ticket T160325 opened).

As one possible hack that could be a way forward on this, I see that the Blazegraph GeoSpatial extension (description on BlazeGraph wiki) allows custom compound data-types to be defined -- which do not necessarily need to include a geospatial element.

Indeed, I still get the same behaviour even if I dispense with the third column entirely, and SELECT just the first two (query) -- so the issue may not involve the counts at all.

Thanks for this Jonas, but given there is already the nice viewer on the page (which I didn't know about when I wrote the bug, because until then I'd only right-clicked on it), perhaps on consideration a better link is just the simple Commons file page, ie 'https://commons.wikimedia.org/wiki/File:{FILENAME}'

Re: my previous comment, nodes that can store both a string and a URL would appear to be necessary to enable T121274 "Provide an RDF mapping for external identifiers" -- even though there are no such value nodes at the moment.

So is there no way to create any kind of compound type that the GUI can interpret appropriately?
-eg date + precision, here
-or url + linktext, on other tickets

Jheald added a comment to T159160: Take account of date precision when displaying dates in WDQS GUI.

So if instead one wrote a query to return a wikibase:Time,
-eg by using p:P569/psv:P569 instead of wdt:P569
could it be possible for the GUI to pick that up and return an appropriately precisioned time?
