Comments and endorsements open for WikiCite plugin for Zotero grant proposalEdit

I have posted a draft grant proposal to develop a WikiCite plugin for the open source reference management software Zotero. The idea is to add citations support to Zotero, retrieve citations data from WikiData, provide an easy way for users to fill in missing citation information and contribute it back to WikiData, and offer citation graph visualizations. I would very much appreciate it if you could post your questions/comments in the proposal discussion page. Please, endorse the proposal if you think it may be worth it. Thanks! --Diegodlh (talk)

so apparently me personally adding data about myself to Wikidata has been flagged as spam and self promotion?

Surely if i have a wikidata profile, and i add my social media links, or an article ive been featured in which is factual information, that cant be seen as spam.

How does that even work?  – The preceding unsigned comment was added by Craigcampbell0302 (talk • contribs).

Dean Court Hotel, YorkEdit

The Dean Court Hotel in Duncombe Place, York, England, comprise two distinct groups of buildings: numbers 1, 2 and 3 Duncombe Place (Q26549206) and numbers 4, 5 and 6 Duncombe Place (Q26549207). These are two groups of what were houses that are now parts of the hotel. Each group is separately identified as being buildings of heritage interest and Wikidata has two separate entries for them. So far, so good. :)

Commons has one category for the Dean Court Hotel: c:Category:Dean Court Hotel, York. This category is included on (Q26549206) under 'other sites' but I am unable to include it on (Q26549207) as it is already being used. What is the solution here please? Thank you, --Malcolmxl5 (talk) 19:14, 17 October 2020 (UTC)

Make a new Wikidata item for the whole thing, and list the other items as parts? Ghouston (talk) 03:58, 19 October 2020 (UTC)
An item for the function (the hotel) and separate items for the buildings as parts, that could work (I’ve realised also there’s a third building that is part of the hotel: 21, High Petergate (Q26548945)). I shall have to write an article on the hotel and buildings, I think. :) Thanks, --Malcolmxl5 (talk) 19:03, 20 October 2020 (UTC)
The relationship between the hotel and the buildings is probably occupant (P466). Ghouston (talk) 08:09, 23 October 2020 (UTC)
Yes, that would logical. --Malcolmxl5 (talk) 17:12, 24 October 2020 (UTC)

Ontology fix for "badges"Edit

All digital badges (including Wikimedia badges) are now appearing as <instance of> "clothing" because up the tree, they are subclasses of badge (Q336533). I'm not sure where (or how) to break this chain - any ideas? Clearly all (notional) badges are not clothing accessories. - PKM (talk) 22:43, 22 October 2020 (UTC)

Where does the Yeti live?Edit

Mystical creatures often stay in a region of their liking, for instance the legendary Yeren (Q2006961) lives in the moutains of Hubei (Q46862).

What property should I use to document that?

Thanks! Syced (talk) 00:31, 23 October 2020 (UTC)

endemic to (P183), perhaps, or taxon range map image (P181) if you have a map. Ghouston (talk) 01:51, 23 October 2020 (UTC)
Are we talk about an individual or the species of Yeti's? If it's an individual residence (P551) seems the nearest. If we are talking about the species then what Ghouston said. ChristianKl❫ 20:37, 23 October 2020 (UTC)

Political GraveyardEdit

Can someone peek at Property:P8462, the links do not work. I think the scheme has changed for the database. --RAN (talk) 00:59, 23 October 2020 (UTC)

@Richard Arthur Norton (1958- ): User:GZWDer adjusted the formatter URL to bypass the Wikidata UI problem. It takes a little while for that to come into effect; if you purge a page with one of these id's now it should work though. ArthurPSmith (talk) 16:20, 23 October 2020 (UTC)
OK, I'll wait and check tomorrow, btw, what is the secret to getting the new scheme? When I visit the website via Google, all I get is a page for a surname. --RAN (talk) 19:47, 23 October 2020 (UTC)
@GZWDer: I see what the problem is, the Unicode for # is being interpreted as ASCII code for #. See that "archer.html#811.30.85" is converted to "archer.html%23811.30.85" when it becomes a URL, giving an error. Click on the two examples at Property:P8462 and see if it happens to you. The error must be in the "format as a regular expression" formula. --RAN (talk) 02:17, 25 October 2020 (UTC)
The problem is the UI automatically URL-encodes all special characters in any id. The external-id tool undoes that encoding and forwards you to the right place. ArthurPSmith (talk) 16:50, 26 October 2020 (UTC)

John Fraser vs John FraserEdit

Hello, I discovered there is some confusion between John Fraser (Q1700123) and John Fraser (Q94122683) but the situation is more complicated than usual so I am asking for second opinion. In my view, identifiers in John Fraser (Q1700123) (VIAF: 14256973) point to a writer born in *1932 rather than to an actor born in 1931. However, the interwiki links all point to the actor. The item storing correct actor's identifiers is John Fraser (Q94122683) (VIAF: 41145971492532331970). Should we keep John Fraser (Q1700123) for the actor and swap the identifiers, or move interwiki links to John Fraser (Q94122683)? Vojtěch Dostál (talk) 07:36, 23 October 2020 (UTC)

I'd keep John Fraser (Q1700123) as the actor, given the descriptions, sitelinks, birth date and occupation. From the history it seems that appropriate VIAF ids have been present at times, namely 20774607 (which is now a redirect) and 41145971492532331970, but people have removed them. I'd put them back, and deprecate anything that refers to somebody else. Ghouston (talk) 07:58, 23 October 2020 (UTC)

OK, I created John Fraser (Q100741986) and John Fraser (Q100741993). Q1700123 is now redirected but I will nominate it for deletion once the links from other Wikidata items are fixed by bot.Vojtěch Dostál (talk) 13:00, 23 October 2020 (UTC)

  • Rather than delete it I would convert it into an entry similar to Christopher Turner (Q5113349). In case third parties have are using the entry as an external link already. --RAN (talk) 19:39, 23 October 2020 (UTC)
The community can decide whether to keep Q1700123 as a conflation, or delete it, I have no firm opinion as to whether it is in use anywhere. --RAN (talk) 19:16, 24 October 2020 (UTC)

mw:Help:Extension:WikibaseCirrusSearch or mw:Help:CirrusSearchEdit

Which page would be better as an entry point for people searching on Wikidata?

Currently mw:Help:CirrusSearch is linked, but features used here are described on mw:Help:Extension:WikibaseCirrusSearch. There are probably one or two interface messages where we could update the link from one to the other. --- Jura 11:24, 23 October 2020 (UTC)

Having issues with trial parametersEdit

I've been trying to improve Wikidata's of persons that have been criminaly charged, but I'm having a hard time figuring out how to add that they've been acquitted of their crime, or pardoned from their penalty, or taken and Alfrod plea later on after conviction.*Treker (talk) 04:21, 24 October 2020 (UTC) I'm also not too fond of that general concept of "innocence" and the legaly defined plea of "not guilty" are the same item.*Treker (talk) 04:24, 24 October 2020 (UTC)

  • Anonymous personal attacks should not be given much weight. If you want to criticize another user, how about setting up an account so that we know more about who you are?

  Done Michgrig (talk) 15:44, 24 October 2020 (UTC)


At Talk:Q19546 we have a table of the popes, but there was an import from the Catalan Wikipedia that caused all the early popes to be duplicated, because the Catalan Wikipedia used dates that are slightly off from the canonical dates used by the Vatican. Is there a way to automatically delete them? Or should they be deprecated so that the bot does not add the information again, and the duplication restored? I would prefer deletion and rely on the canonical dates supplied by the Catholic Encyclopedia. --RAN (talk) 19:30, 24 October 2020 (UTC)

  • Is it a transcription error of cawiki or are they dates also found elsewhere? In the later case, it's better to mark preferred whatever is preferred. In the first case, maybe it's worth to tell cawiki about it. --- Jura 13:26, 25 October 2020 (UTC)
@Jura1: I see what the problem is, one source is using the day of the election as the start date of being a pope, and the other source is using the date of the inauguration as the start date for being a pope. The modern popes are all using one date, but the early ones are using a mixture of the two dates, so we are getting two entries. I do not know which one is correct. For a US president the authority does not begin until the inauguration, but you only get a new pope when the old one is dead, so the authority may begin at the election, and the inauguration just a formality. I will write a professor at University of Notre Dame and see if I can get a response. --RAN (talk) 19:39, 25 October 2020 (UTC)

Languages available "Traditional Chinese" and "Chinese"?Edit

At Taiwan Transportation Safety Board (Q4828674) the options for the name include "Chinese" and "Traditional Chinese". Isn't there a way to change "Chinese" to "Simplified Chinese"?

Thanks WhisperToMe (talk) 20:36, 24 October 2020 (UTC)

WhisperToMe, I'm assuming that you are talking about the few labels of the item visible before expanding the full list, and that you want to have simplified and traditional Chinese labels there. Did you try changing your language fallback chain, for example by adding some Babel boxes? whym (talk) 11:31, 29 October 2020 (UTC)

Updating SPARQL federation input review processEdit

wikidata:SPARQL federation input page has been abandoned for some time and on October 8 @Multichill: marked page as historic to make it visible. (discussion) After that, the phabricator ticket phab:T265290 (Review the federation input process for WDQS) was created.

The phabricator ticket defines as a target that adding new SPARQL-endpoints to Wikidata Query Service requires community input on the process. Also, the Search Platform team should not be in charge of deciding which request makes sense and which does not.

After the community decides, there may be technical reasons why and when new endpoints will be added, but defining the community process is one step going forward with the ticket.

One simple process could be (more or less the same as before)

  1. Add proposal of the new endpoint to the wikidata:SPARQL federation input page
  2. Community would review the proposal
  3. If rejected then mark the rejection to the proposal
  4. If approved then the community will create phabricator ticket for a SPARQL endpoint to be enabled where the relevant information is described including a link to the discussion.
  5. When phab ticket is ready and the endpoint is working mark the status of the proposal

--Zache (talk) 09:33, 25 October 2020 (UTC)

Thanks for picking this up. I think the criteria for acceptance should be made very clear to avoid disappointments or needless discussions:
  1. The data in the SPARQL endpoint should be licensed under a free license. Rule of thumb: If Commons accepts the license, you're good. A link to the license should be included in the proposal so it's easy to verify it
  2. The data in the SPARQL endpoint is somehow relevant to combine with Wikidata. Just to prevent people from nominating every free SPARQL endpoint because they can.
Maybe model the flow of requests like Wikidata:Requests for permissions/Bot? Multichill (talk) 10:51, 25 October 2020 (UTC)
I agree with #1, though it is not always so easy to see what is in the endpoint without actually looking into it. (examples: Wikidata:SPARQL_federation_input#European_Environment_Agency_SPARQL_endpoint) About #2, if we are gonna create separate pages for approvals it could be more useful to just to archive the discussion part to the talk page for example, and convert the rest of the content as the living documentation of the endpoint. So editors could add new examples and update links to documentation etc. Currently, the biggest blockers for using federation and SPARQL, in general, is that it is hard to know what is in the endpoint and how to access it. --Zache (talk) 11:27, 25 October 2020 (UTC)
Multichill Is there a bit more reasoning behind the license requirement? I ask because it is distinctly different than Wikidata's license requirement (CC0). If we allow federation to depart from that, would there be any value in going further, such as allowing "non-commercial" licenses as well? That would obviously expand the possibility of such a service, but I feel uneasy about it. Matthias Winkelmann (talk) 14:01, 28 October 2020 (UTC)
The reasoning behind this licensing restriction is that Wikimedia websites should only offer free content. Multichill (talk) 17:35, 28 October 2020 (UTC)

If you wonder what federated input or queries mean then the simple answer would be that those are database queries that can use multiple databases simultaneously. The common use case in Wikimedia is to query both Structured Data on Commons and Wikidata and combine the results. However, it can be other sites too. I wrote an example query to Commons for a query which uses Wikidata, Commons structured data, Europeana (Q234110) and Finto (Q61677804) for reading subjects of photo from Europeana and then converting them to Commons categories. In the Wikipedia context example, it can be used for reading numerical data like population time series which are currently too complex to store in Wikidata from dedicated services like Eurostat (Q217659). --Zache (talk) 08:10, 26 October 2020 (UTC)

Golden Song by Harry StylesEdit

Golden (Q100701128) and Golden (Q91250107) both relate to the song "Golden". I don't know the correct modeling for compositions and releases, so maybe they should stay separate. Can someone please complete these items? By the way they were both targeted by vandals, I requested semi-protection. --Pyfisch (talk) 09:52, 25 October 2020 (UTC)

I've merged the two items because they are evidently about the same object - a song that is part of an album. Michgrig (talk) 14:47, 25 October 2020 (UTC)
@Michgrig: That is not correct. Per Wikidata:WikiProject Music overview the track should not be merged with the release. Golden (Q100701128) is the single and Golden (Q91250107) is the track that is on the single and album. - Premeditated (talk) 10:17, 26 October 2020 (UTC)
@Premeditated There was no indication that Golden (Q100701128) is a single, otherwise I wouldn't have merged these items. If you take a look at previous versions, you'll see that the former was about a song from an album. If there are articles about both a song and a single, my merge can be safely reverted. Michgrig (talk) 11:30, 26 October 2020 (UTC)
@Michgrig: If you now look at Golden (Q100890626) and Golden (Q91250107) there is a clearly difference between composition and vocal track. Another example of why this modeling is favorable:
|--Stardust (Q91190107): The composition
|--Stardust (Q1543022): The lyrical adaptation of the song
|--Stardust (Q93717770): The vocal track by Willie Nelson
|--Stardust (Q94544075): The vocal track by Rod Stewart

Horsedrawn tram or railway?Edit

Q874504 is an example of an horsedrawn railway. However Q832003 is also used for typical Horse-drawn trams (see Commons:Category:Horse-drawn trams). I suggest that a seperate data item is created for 'Horse-drawn trains' typicaly used by very early railways such as Q874504.Smiley.toerist (talk) 11:59, 25 October 2020 (UTC)

Wikidata weekly summary #439Edit


What needs to happen to help fix a problem accessing Wikidata from Wikiversity?

Several pages in Wikiversity:Category:Freedom and abundance contain {{cite Q|...}} references that display something like the following:

@Rehman, ChristianKl, Jura1, Jklamo: It looks like I do receive Mathematics pings--there's just no indication in the notification that indicates it is a result of {{Ping project|Mathematics}}, so I didn't connect the dots. (It would be nice if the notification was more informative.) On the other hand, Ontology project pings are definitely not coming through. Turns out, per Template:Ping project/doc, that if there are more than 50 people are in a project list, then none of them receive notifications. Should we start pruning inactive members from lists? — The Erinaceous One 🦔 11:12, 28 October 2020 (UTC)

Alternatively there exists another project notification possibility, used by some project on frwiki : a ping template adds a category to the page, and a template puts the number of pages in this cat on the project main page. The category is removed when the discussion is considered closed by someone by adding a parameter to the ping template. This works, but requires an active behavior of the pingee to watch the project page. author  TomT0m / talk page 15:18, 28 October 2020 (UTC)

Cathédrale or cathédrale?Edit

VIGNERON (talkcontribslogs) reverted my edition of changing "cathédrale Saint-Lazare d'Autun" for "Cathédrale Saint-Lazare d'Autun" at Q611944. The issue is the capitalization of an noun. The rules at [1] say that "...however proper nouns such as the names of specific people, specific places, specific buildings, specific books, etc., should be capitalized." "Cathédrale Saint-Lazare d'Autun" is the name of an specific building. So, I think the name cathédrale in this case (and similar) should be capitalized. GualdimG (talk) 07:25, 27 October 2020 (UTC)

  • If it's about the French label, please use Help:Label/fr. --- Jura 07:33, 27 October 2020 (UTC)
Hi @GualdimG:,
The names of specific buildings are "cathédrale Saint-Lazare d'Autun"@fr and "cattedrale di Autun"@it. Not entirely sure for italian but 100% sure for French. Take a look at the wikipedia articles, the introduction starts with "cathédrale Saint-Lazare d'Autun" and "cattedrale di San Lazzaro".
Cheers, VIGNERON (talk) 07:38, 27 October 2020 (UTC)

I couldn't find policy that specifying edit interval limit per time-unit (have searched 'insource:"edit interval"'). Could someone help me with it? Thanks.--Semi-Brace (talk) 12:33, 27 October 2020 (UTC)

8 edits/min for IPs and Newcomers (i.e. not yet "autoconfirmed"), and 90 edits/min otherwise. The limitation is technically enforced by MediaWiki, and the values are default values for Wikimedia projects. —MisterSynergy (talk) 12:54, 27 October 2020 (UTC)
Thanks for telling me that, I'm glad to hear. --Semi-Brace (talk) 12:58, 27 October 2020 (UTC)
In addition, for uses of the API, there's a maxlag parameter which signals a requirement for the user (normally a bot) to decrease its edit rate when load on the servers is too great - see e.g. --Tagishsimon (talk) 22:49, 28 October 2020 (UTC)

Idea for item updateEdit

You found a good idea to add product or material produced (P1056) on Nokia (Q1418)? --2001:B07:6442:8903:7174:8606:ACD2:282E 17:04, 27 October 2020 (UTC)

Can I edit with this account? (alternate account)Edit

I've made this alternate account with the purpose to be used on my streaming computer. I'd like this account to be limited from the beginning. I will link to my main username User:Datariumrex and I've linked back from it. RustProton (talk) 17:16, 27 October 2020 (UTC)

There is no problem with having multiple accounts, so long as you don't use them to evade a block/ban or try to manipulate a consensus discussion by using the accounts to support each other. The fact that you have made an open statement on the user page of each account about the link is a positive. From Hill To Shore (talk) 17:35, 27 October 2020 (UTC)
I do see this as a valid use for an alternative account.
@From Hill To Shore: Given our current rules making an open statement on the user page is not only positive but required. ChristianKl❫ 15:23, 28 October 2020 (UTC)
It is a positive that the user has made an open and frank statement about the link prior to seeking clarification on whether what they are doing is allowed. I have encountered other editors in the past who have not been as honest. From Hill To Shore (talk) 23:08, 28 October 2020 (UTC)

Ranks messed up in this one itemEdit

Hiya! Could some gentle soul perhaps straighten the ranks of the software version identifier (P348) in Q21041255. Now 2.7.4 would seem to get the lime light instead of newer versions. I would do it myself except it can't be done without JavaScript I think... --Palosirkka (talk) 20:57, 27 October 2020 (UTC)

@Palosirkka, it has nothing to do with JavaScript. I changed the rank of version 2.7.4 from preferred to normal, and the rank of the latest version from normal to preferred. For more details, please see Help:Ranking. Michgrig (talk) 06:26, 28 October 2020 (UTC)
@Michgrig: Thanks for changing the pref rank to normal. I wonder if setting the latest to preferred will cause the same problem once a new version appears. Or are they supposed to go change the rank of the other older release. Should they all be normal? Ranks have nothing to do with JS but editing Wikidata has. Try it. :) --Palosirkka (talk) 10:35, 28 October 2020 (UTC)
@Palosirkka: "I wonder if setting the latest to preferred will cause the same problem once a new version appears." - Yes, it will. As soon as a new version appears, the ranks must be changed. This way, Wikipedia articles will display only the latest version. If all versions are normal, then all of them will be displayed in Wikipedia. Michgrig (talk) 13:26, 28 October 2020 (UTC)

Can't set ISQ dimension propertyEdit

I've just tried to set the ISQ dimension (P4020) of specific impulse by mass (Q100793317) to "\mathsf{L} \mathsf{T}^{-1}" (that is to say, the ISQ dimensions of velocity in math markup). However, when attempting to publish the change, I'm getting the message "Could not save due to an error. Bad value type unknown, expected string". The property ISQ dimension (P4020) has datatype "Mathematical expression", and the value I'm using certainly looks like a valid expression: it's directly cut-and-pasted from the "ISQ dimension" field of velocity (Q11465).

I've done a bit of testing, and seem to get the same error regardless of the string I enter, whether or not it's a valid math formula. I also get similar results if I try to set defining formula (P2534), so this might possibly be a problem with other types of math expression property.

What's going wrong here? Can anybody help me with this, please? -- The Anome (talk) 07:47, 28 October 2020 (UTC)

I had filed the same issue yesterday: Toni 001 (talk) 09:28, 28 October 2020 (UTC)

There seems to be a high degree of conflation between Carthage (Q6343) and Ancient Carthage (Q2429397). Do we have a subject-specialist who could sort them out, and make the distinction between them clearer? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 13:36, 28 October 2020 (UTC)

Type @ in searchEdit

If I type @ in search bar on left site then ill getreuslts but If I type it in Search ill get no resuls and also why Wikipdia search is so bad? Eurohunter (talk) 14:39, 28 October 2020 (UTC)

1. They're two distinct systems, the first capable of invoking the second. 2. CirrusSearch is rather good, but like any search technology, it is not great at everything. It will not search for metacharacters without reaching for regex, afaics, and even then it finds it all a bit hard. More info here:

24-hours online meetup for the Wikidata birthdayEdit

Hello all,

As a reminder, the 24-hours online meetup to celebrate Wikidata's birthday is starting today at 17:00 UTC/GMT (18:00 in Central Europe), in a bit less than two hours.

This informal discussion is open to everyone who would like to chat about Wikidata and virtually meet other people from the community. The main topic is "what makes you feel enthusiastic about Wikidata" and some people will facilitate certain slots with a specific topic. You can find more information here.

You're welcome to jump in at any point that is convenient for you! To access the call, you will first need to register here (free of charge, valid email address needed). An individual link to the BigBlueButton call will then be sent to you one hour before the beginning of the event. (the service provider complies to GDPR and the email address you provide will be deleted after the event, we will not access or reuse it in any way)

We're looking forward to chat with you and to learn more about your favorite projects, tools or anecdotes on Wikidata!

If you encounter any technical issue, feel free to contact me by email. Cheers, Lea Lacroix (WMDE) (talk) 15:04, 28 October 2020 (UTC)

Can't join the call, but the birthday logo is super cute! Matthias Winkelmann (talk) 20:26, 28 October 2020 (UTC)
I registered about an hour ago. I received an immediate confirmation of my order, but no joining link for the BigBlueButton event. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:44, 29 October 2020 (UTC)

Idea for item updateEdit

I wish to add on the item Nokia (Q1418) the section product or material produced (P1056) and add all the products made by Nokia , for example Nokia 5110, Nokia 3210, Nokia 7110 and the other Nokia models. It is eligible for Wikidata? --2001:B07:6442:8903:808B:BAD6:9C9A:7BF8 17:40, 28 October 2020 (UTC)

Sucky idea. Much better to create items for the company's products. As has already been done. Nokia 5110 (Q2016083) &c --Tagishsimon (talk) 22:16, 28 October 2020 (UTC)
@Tagishsimon: Apple Inc. (Q312) also has the section product or material produced (P1056). Why Apple yes and Nokia no? --2001:B07:6442:8903:6DEE:8CDE:9DC7:6FC9 09:18, 29 October 2020 (UTC)
It's a useful thing do do from a pespective of redundancy. But the cost is bloated items which do not play well with the RDF serialisation process, besides making the items a PITA to navigate. Given that the data is redundant, because it is (or can be) represented in discrete child items, the question would be, why do it? There are, I'm afraid, all sorts of properties for parent items that are more sanely catered for by pointing child items at the parent, given the technical constraints under which wikidata labours. Being able to point to examples of unnecessary bloat is not a good reason for adding more bloat. Clearly, mine is just a view, and if you want to add cruft to an item, knock yourself out, but don't kid yourself that it's unambiguously the case that you're improving wikidata. --Tagishsimon (talk) 13:28, 29 October 2020 (UTC)

Is there a property for adding quotes from people?Edit

Hi all

Is there a property for adding quotes from people? I know there's one for quoting from books but not sure if that is usable for this purpose.


--John Cummings (talk) 23:18, 28 October 2020 (UTC)

No & no, afaics. You're thinking quotation or excerpt (P7081). --Tagishsimon (talk) 00:20, 29 October 2020 (UTC)
Probably best to simply use Wikiquote (Q369), rather than clutter items with what could easily be hundreds of trivial, unstructured quotes. -Animalparty (talk) 04:13, 29 October 2020 (UTC)

Automated finding references: dump and dashboardEdit

Hello all,

As you may know, in May 2020 we released new data for automated references, as well as a game that you can use to associate references with statements. We released this game containing 4200 potential references (see statistics). In the meantime, we parsed many more websites and collected 529K potential new references.

These new references will not be added to the game, because they are too many for their relevance to be checked by hand. As requested by some of you after the previous announcement, we published the list of all references in a dump available here.

Subsets of this dump can be reused by bots and tools, however, we advise you to be careful when using it and to not mass import them to Wikidata without careful review: it is quite raw, some references may be wrong or irrelevant. In order to help you analyze these references and filtering the most useful ones, we are also providing a dashboard containing an overview of the judgements made in the game so you can see which parts are more likely to be of higher or lower quality.

We’re happy to release the dumps and the dashboard just in time for the Wikidata birthday :)

If you have any questions or encounter issues with the dump or the dashboard, please let us know on the talk page. Cheers, Lea Lacroix (WMDE) (talk) 08:56, 29 October 2020 (UTC)

Better Item quality judgments from ORESEdit

Hello all,

Wikidata’s content is growing and our data is used in more and more high-profile places. This means the pressure around data quality is rising. We want to provide people with good data. One important piece in the data quality puzzle is being able to understand where we currently stand quality-wise and how that changes over time. We need to be able to do this at scale and in an automated and repeatable way because no-one of us wants to do this by hand for 90 Million Items for sure.

That’s where ORES, the machine learning system, comes in. One of the things it can do is judge the quality of an Item. Or to be more exact it can judge some aspects of the quality of an Item. It puts each Item into a quality class between A (amazing) and E (ewwww, terrible). It’s been doing this for a while already but the quality judgments it provided were not very good. The reasons for this were that it took only a limited number of signals into account (that’d be something like the number of References on the Item or the number of Labels) and because it was trained on rather old data. Since then Wikidata’s data has changed a lot so ORES could not tell what to do with the new kinds of Items like astronomical objects because it had never seen them before.

We wanted to improve that and make the quality judgments ORES provides better. We did this by:

  • adding a number of new signals (e.g. does this Item have an image attached)
  • changing existing signals (e.g. missing references on external ID statements no longer punish the Item so much)
  • retraining the model on more current data so it better understands scientific papers, astronomical objects, etc.

While we were at it we also wanted to better understand how data quality changes over time on Wikidata. Before we only looked at the global average quality score. But how do Items change over time? How many Items are being improved from D to C or even B class for example? To better understand this we started creating diagrams like the following one. It shows the development from January 2019 to January 2020.


We’re happy to present these improvements for Wikidata birthday, and we hope this will help us get a better and more accurate view of the data quality on Wikidata now.

If you want to see the quality score near the header on each Item you can include the following user script in your Common.js page: importScript("User:EpochFail/ArticleQuality.js")

What’s coming next on the same topic?

  • ORES can’t judge all aspects of quality. It for example can not tell if a statement is generally considered true. We will look at ways of judging this aspect of quality as well but it’s considerably harder. If you have ideas how to go about it let us know.
  • We will build a small tool that’ll make it possible for you to provide a list of Items and then get the quality of that subset of Wikidata as well as the lowest and highest quality Items. This will hopefully help wiki projects etc to have a good overview of their data.

If you have any questions or feedback, or want to keep discussing about Item quality, feel free to use this talk page. Cheers, Lea Lacroix (WMDE) (talk) 09:03, 29 October 2020 (UTC)

Save the date! WikidataCon distributed conference on 29-30-31 October 2021Edit

Hello all,

On this day of Wikidata’s birthday, I’m excited to announce some news about the next edition of the WikidataCon.

The WikidataCon is an event organized by Wikimedia Germany and focused on the Wikidata community in a broad sense: editors, tools builders, but also 3rd party reusers, partner organizations that are using or contributing to the data, the ecosystem of organizations working with Wikibase. The content of the conference will have some parts dedicated to people who want to learn more about Wikidata, some workshops and discussions for the community to share skills and exchange about their practices, and some space left to include side events for specific projects (WikiCite, Wikibase, GLAM, etc.).

During the first two editions, we gathered an international crowd in Berlin for a few days. However, as the global COVID pandemic is still hitting the world, and the forecast for 2021 doesn’t indicate much improvement, the situation doesn’t allow us to plan a traditional onsite international conference. In order to allow the event to take place, and to ensure the safety of all participants, we had to make some clear decisions. In 2021, we will not gather all participants in Berlin, and we will avoid any international travel. Instead, we are experimenting with a hybrid format for the conference: most of the content and interactions will take place online, and small, local gatherings will be possible, if the situation allows it.

In a similar way to the distributed Wikidata birthday events, we will encourage Wikimedia chapters, local groups and communities to organize their part of the event, to support and gather people inside their country, and to contribute to the content, for example with running talks, workshops and discussions. Wikimedia Germany will provide the technical infrastructure and support the coordination of these distributed events. We’re already inviting Wikimedia organizations to include the event in their 2021 plan (especially if you’re requesting an APG), and to reach out to me if you want to be involved in the distributed conference.

On top of this, we would like to partner with a Wikimedia organization outside of Europe/North America, to strengthen the Wikidata community in their country and to allow a fairer distribution of content and speakers. We are currently evaluating several possibilities, focusing on groups who have been very active with Wikidata-related events over the past years. Our criteria include not only the motivation and past activities, but also the ability of the group to support part of the WikidataCon organization workload. The choice of the partner organization will be announced at the end of November. If you would like to know more about the process, feel free to contact me off-list and I’ll be glad to give you some details.

In these quite unpredictable times, organizing an event is a challenge, and the WikidataCon 2021 will definitely be one of a kind: we will have to adapt, to be agile, to make the best out of the situation, and to work closely with the local Wikidata groups all over the world.

Since the first WikidataCon in 2017, I am deeply committed in providing a nice experience for everyone and making sure that this event remains a gathering for and by the Wikidata community. I’m really excited to coordinate this project and run this new experiment with you all!

If you’re interested in joining the effort, if you have questions, suggestions for formats, etc.: feel free to use this talk page or to reach out directly to me.

Old Georgian statesEdit

Hello, I don't know very much about Georgian (caucasus) history. I somewhat think there is a mess with, say, Q56089236 and Kingdom of Imereti (Q1069959) and for instance / . Could anyone of better history knowledge help clean and fix their items ? Bouzinac💬✒️💛 21:04, 29 October 2020 (UTC)

Sacral architecture vs. religious buildingEdit

There seems to be a mix-up of two concepts in sacred architecture (Q47848), which is supposed to be about the architectural practises. However, it is a subclass of religious building (Q24398318) which must be wrong. I already moved the three site-links which were definitely wrong, but as I am not familiar how to model architecture and it gets late here - can someone else take over and clean those two items up?
