Hello team :)
So while I'm helping with the Wikidata - Schema.org mappings, a request came in to expose subcategories of an existing Wikipedia category.
For example, say I start with this topic: https://www.wikidata.org/wiki/Q27119725 Parking facilities
The topic's main category is shown as "Category:Parking facilities" and that has links to Wikipedia, specifically a Wikipedia category link, and where the WP category page has subcategories that I would like to expose somehow in whichever way is *easiest* currently with our tools, apis, etc.
Can it all be done in SPARQL against some services that already expose WP subcategories given a specific category ? Or is there an API that does this already ? other tools that might expose WP categories ?
The IDEAL GOAL is to query 'equivalent class' = schema.org/ParkingFacility and get back the WP categories *in one shot or query or api call.*
http://schema.org/ParkingFacility
- Parking facilities in India https://en.wikipedia.org/wiki/Category:Parking_facilities_in_India - Parking facilities in the United States https://en.wikipedia.org/wiki/Category:Parking_facilities_in_the_United_States
- Aircraft hangars https://en.wikipedia.org/wiki/Category:Aircraft_hangars
- Garages (parking) https://en.wikipedia.org/wiki/Category:Garages_(parking) - Railway depots https://en.wikipedia.org/wiki/Category:Railway_depots
Any gurus ?
Hi!
Can it all be done in SPARQL against some services that already expose WP subcategories given a specific category ? Or is there an API that does this already ? other tools that might expose WP categories ?
I don't think subcategory relationship is not recorded in Wikidata. E.g. https://www.wikidata.org/wiki/Q7361750 contains https://www.wikidata.org/wiki/Q14436424 but neither have any indication of that. The problem I guess is that category hierarchy is different on all wikis, so it's hard to have one property that expresses it on Wikidata.
You could do through "subclass of" and "category's main topic" but not sure that'd capture all. E.g.: http://tinyurl.com/h7qpcdn but that only captures one subcategory, since other items don't have the same hierarchy in Wikidata.
Thanks Stas,
So, hmm...we'd have to build our own parser or something is what your saying ? Because Wikidata doesn't have those kinds of connections in its graph and also doesn't have a SPARQL service yet against the Wikipedia API:Categorymembers https://www.mediawiki.org/wiki/API:Categorymembers to deduce those subcategories, right ?
How difficult is it for someone to create a service like the LabelService , but instead using the WP Categorymembers API ? Or do you have some other ideas ?

Stas,
This is what I was thinking would have already been integrated into Wikidata somehow, somewhere, ideally as a SERVICE to call in SPARQL if there were any Category Labels , maybe another serviceParam for the label Service that could take another serviceParam to retrieve the subcategories ?

Right now, we do not support calls out to external services, due to security issues it may produce. However, making limited API to specifically mediawiki API may be possible, it's actually an idea we haven't considered before and may be possible to do. Needs some thinking though, so don't expect it to be done by next week :) but interesting, I'll look into it.
We probably will need to use generator since we'd need Wikidata IDs, but something like this:
/w/api.php?action=query&format=json&prop=pageprops&generator=categorymembers&ppprop=wikibase_item&gcmtitle=Category%3AParking&gcmprop=ids%7Ctitle&gcmtype=subcat
should work. It needs some code to be able to properly build and consume queries, but not impossible.
Cool. Yeap, you got the idea now.
OK, We'll stay tuned for a future new Service !
Schema.org and Google and the World thank you Stas :)

DBpedia has the category data in RDF. The last release of DBpedia also included Wikidata - it should be possible to query the combined dataset there.

Hi Thad,
One quick red flag - I'm not sure how familiar you are with the category system, but automatically parsing it without sanity-checking can very quickly lead you into a minefield. There are a substantial number of category trees which seem reasonable at first, but rapidly go in unexpected directions.
For example, if you start at "Category:Road transport" on enwiki and go two categories deep, you get "Category:Parking facilities" - so far, so good - but you also get "Category:The Hitchhiker's Guide to the Galaxy", "Category:Songs about buses", and "Category:Cycling journalists".
There are a few pairs of categories which contain each other directly, and a much larger number which contain each other once you go a few levels of subcategories deep & so go in endless loops. And, of course, a clean category tree in French might be a mess in German, or vice versa.
None of this is to say "don't do it", but rather "don't expect it to be clean and tidy" :-)

Thanks Andrew but I know and see the pitfalls. The use case is only 1 level deep and to be treated not as a Category but instead as simply something "Related" or "Relative" to the topic. Keeping within those 2 constraints from my tests seems to work reasonably well. Beyond those constraints... I agree, its the wild west and not something that we are interested in.

Hoi, Magnus does use subcategories extensively in his tools. It is not WDQS but it is data. Be warned, many of the "lists" and "categories" in Wikidata are not only this but are reused for other purposes. Thanks, GerardM

Hi Thad,
If there are owl:equivalentClass mappings in some Linked Data Space, and the SPARQL service associated with said Data Space supports owl:equivalentClass reasoning, then the answer to your question is yes.
What unknown right now is the class mappings between Wikidata and Schema.org. If a dump of those exist, the rest is trivial :)
Class mappings are almost complete Kingsley. We were trying to get Wikidata to the point where it is easy for folks to do trivial queries right inside WDQS as part of WD Goals for 2016.

Is there a dump of the class mappings anywhere? Fundamentally, once you have those mappings the result you desire will be achievable and demonstrable via a live Linked Data Space.

Thad,
Here is a post (brought up to date in last day) that demonstrates owl:equivalentClass reasoning and inference. Once I have a link to the new mappings I will integrate into this demo.
Note, this particular LOD Cloud Cache instance has 30 Billion+ triples against which the owl:equivalentClass inference is being applied, at query evaluation time.

Kingsley,
The mappings are already in Wikidata (we still have a few properties left to map, but the classes are done, except for a few in pending.schema.org. You can just query them in some fashion such as this: http://tinyurl.com/h9vjqd8

The topic's main category is shown as "Category:Parking facilities" and that has links to Wikipedia, specifically a Wikipedia category link, and where the WP category page has subcategories that I would like to expose somehow in whichever way is *easiest* currently with our tools, apis, etc.
Can it all be done in SPARQL against some services that already expose WP subcategories given a specific category ? Or is there an API that does this already ? other tools that might expose WP categories ?
The IDEAL GOAL is to query 'equivalent class' = schema.org/ParkingFacility and get back the WP categories *in one shot or query or api call.*
http://schema.org/ParkingFacility
Parking facilities in India https://en.wikipedia.org/wiki/Category:Parking_facilities_in_India
- Parking facilities in the United States
https://en.wikipedia.org/wiki/Category:Parking_facilities_in_the_United_States
- Aircraft hangars
https://en.wikipedia.org/wiki/Category:Aircraft_hangars
- Garages (parking)
https://en.wikipedia.org/wiki/Category:Garages_%28parking%29
- Railway depots
https://en.wikipedia.org/wiki/Category:Railway_depots
Any gurus ?
Hi Thad,
If there are owl:equivalentClass mappings in some Linked Data Space, and the SPARQL service associated with said Data Space supports owl:equivalentClass reasoning, then the answer to your question is yes. What unknown right now is the class mappings between Wikidata and Schema.org. If a dump of those exist, the rest is trivial :)

Thad,
Not getting the point you are trying to articulate i.e., the solution isn't comprised strictly of https://www.wikidata.org/wiki/Property:P1709 https://www.wikidata.org/wiki/Property:P1709 relations.
I am assuming https://www.wikidata.org/wiki/Property:P1709 https://www.wikidata.org/wiki/Property:P1709 identifies equivalentClass relations i.e., https://www.wikidata.org/wiki/Property:P1709 https://www.wikidata.org/wiki/Property:P1709 owl:equivalentProperty owl:equivalentClass .
You should be able to articulate the equivalent of the following, using SPARQL against Wikidata:
SELECT DISTINCT ?s ?relation ?o WHERE { ?s owl:equivalentClass ?o. BIND (owl:equivalentClass AS ?relation) FILTER (isIRI(?s)) FILTER (isIRI(?o)) } LIMIT 100

Kingsley,
You might ask others on the list who could help more with providing the WD - Schema.org mappings or get them into a format that you want...or an RDF dump file.
I just don't have the knowledge to assist you with that via SPARQL. (i.e., I am not a SPARQL guru)

The topic's main category is shown as "Category:Parking facilities" and that has links to Wikipedia, specifically a Wikipedia category link, and where the WP category page has subcategories that I would like to expose somehow in whichever way is *easiest* currently with our tools, apis, etc.
Can it all be done in SPARQL against some services that already expose WP subcategories given a specific category ? Or is there an API that does this already ? other tools that might expose WP categories ?
The IDEAL GOAL is to query 'equivalent class' = schema.org/ParkingFacility and get back the WP categories *in one shot or query or api call.*
http://schema.org/ParkingFacility
Parking facilities in India https://en.wikipedia.org/wiki/Category:Parking_facilities_in_India
- Parking facilities in the United States
https://en.wikipedia.org/wiki/Category:Parking_facilities_in_the_United_States
- Aircraft hangars
https://en.wikipedia.org/wiki/Category:Aircraft_hangars
- Garages (parking)
https://en.wikipedia.org/wiki/Category:Garages_%28parking%29
- Railway depots
https://en.wikipedia.org/wiki/Category:Railway_depots
Any gurus ?
Hi Thad,
If there are owl:equivalentClass mappings in some Linked Data Space, and the SPARQL service associated with said Data Space supports owl:equivalentClass reasoning, then the answer to your question is yes. What unknown right now is the class mappings between Wikidata and Schema.org. If a dump of those exist, the rest is trivial :)

Thad,
I assumed an understanding of how wikidata models properties. Anyway, I'll take a look as what I requested should be possible, assuming there isn't new bent on RDF data modeling that exist in this data.
I'll take it from here.
Thanks for your assistance :)

Basically, I am using SPARQL-FED to produce the desired result using a variety of RDF related document types (JSON-LD. RDF-Turtle, HTML5+Microdata, and XHTML+RDFa).
We will load this into the DBpedia DBMS which will make this data available via SPARQL and relevant Linked Data pages, now that the new 2016-04 release is live [1].

Nice Kingsley! Great work. So now....the bad news and where we need further help still :)
I do want to let everyone know however that within Classes and Properties...there are a slight few mappings that were taken as an opinionated view
I.E. they may slightly conflict with other views of the mappings in Languages that are not English. Or might not seem correctly mapped or aligned. But I think most folks know that around here and deal with that everyday in Wikipedia and Wikidata.
Still, we encourage all communities to review the Schema.org-WD mappings and voice any issues, errors, mistakes, or alternative viewpoints in this Wikidata mailing list or the Schema.org mailing list or our Schema.org Github issues.

Oops ! one more thing about the mappings that I forgot to mention to all. Which is very important.
That is were schema.org holds its work-in-progress or review of a draft idea for Classes (Types) and Properties.
We have already mapped several of them that are currently in http://pending.schema.org and those also show in the Schema.org-WD mappings. There is some usefulness for doing this ahead of time, so that way we can see upcoming overlap and raise issues on either WD or Schema.org side. BUT NOTE: http://pending.schema.org is not a final view or official release and so those particular mappings against that subdomain MIGHT BE SUBJECT TO CHANGE IN THE FUTURE.
As already mentioned in our Schema.org issue, We (Thad and others) will continue to update the mappings inside Wikidata as we go forward with Schema.org changes and releases and where things move out of pending and into our current release.

Kingsley,
The http://pending.schema.org namespace will show up as this in RDF Turtle
ns1:Q1251750 owl:equivalentClass ns3:Distillery .
and this way in JSON-LD
{
- @id: "http://www.wikidata.org/entity/Q1251750", - equivalentClass: "http://pending.schema.org/Distillery"
},

Thad,
I assume you will have @context in the JSON-LD doc preamble with regards to owl: namespace mapping to "equivalentClass" ?
Anyway, here are some live examples of the effects of mappings (classes and properties) across wikidata, schema.org, and dbpedia vocabularies using the latest edition of DBpedia.

Kingsley,
Hmm. I am actually not sure about the preamble. That is something you will have to discuss with DanBri on the Schema.org mailing list.

Nice Kingsley! Great work. So now....the bad news and where we need further help still :)
I do want to let everyone know however that within Classes and Properties...there are a slight few mappings that were taken as an opinionated view
I.E. they may slightly conflict with other views of the mappings in Languages that are not English. Or might not seem correctly mapped or aligned. But I think most folks know that around here and deal with that everyday in Wikipedia and Wikidata.
Still, we encourage all communities to review the Schema.org-WD mappings and voice any issues, errors, mistakes, or alternative viewpoints in this Wikidata mailing list or the Schema.org mailing list or our Schema.org Github issues.

Thad,
These mappings can end up in their own special named graph, in a quad store. Net effect, massaging and improvements can occur forever without turning anything on its head. For instance, I can use the mappings named graph as the basis for an inference rule that's only invoked conditionally (in the case of Virtuoso that would via a pragma).
I will update or make a new blog post with live examples.
Anyway, we should be set :)
