  • great work in Wikidata
BrokenSegue (talkcontribs)

You modified the crunchbase identifier on Fyber (Q100319972) but it seems your edit points at a non-existent entry? How are you making these updates?

couldn't there be other/lots of identifiers that don't work in all lowercase? How do we know this didn't break lots of items

Vladimir Alexiev (talkcontribs)
  • I've seen thousands of CB identifiers and never seen one in uppercase.
  • The prop definition says "format as a regular expression: [^A-Z \/]+ ; constraint status: mandatory constraint" (but has no reference). I didn't add this constraint.
  • I'm not changing identifiers to lowercase en-masse, just this one
  • I've added http://km.aifb.kit.edu/services/crunchbase/ en-masse which unfortunately has errors. In addition to those fixed by batch described in "Crunchbase bug" below, I'm currently working out many more

ok thanks for doing this

Based on this edit, the task you just ran appears to have a bug of some sort.

Hi Vladimir,

Based on your questions on my talk page, you seem to be working on artists regularly. Could you have a look at Q2146291 and Q41323135? It seems the data on two different artists are mixed up here (see RKDartists links).

Best, ~~~~

Call for participation in the interview study with Wikidata editors

Kholoudsaa (talkcontribs)

Dear Vladimir Alexiev,

I hope you are doing good,

I am Kholoud, a researcher at King’s College London, and I work on a project as part of my PhD research that develops a personalized recommendation system to suggest Wikidata items for the editors based on their interests and preferences. I am collaborating on this project with Elena Simperl and Miaojing Shi.

I would love to talk with you to know about your current ways to choose the items you work on in Wikidata and understand the factors that might influence such a decision. Your cooperation will give us valuable insights into building a recommender system that can help improve your editing experience.  

Participation is completely voluntary. You have the option to withdraw at any time. Your data will be processed under the terms of UK data protection law (including the UK General Data Protection Regulation (UK GDPR) and the Data Protection Act 2018). The information and data that you provide will remain confidential; it will only be stored on the password-protected computer of the researchers. We will use the results anonymized to provide insights into the practices of the editors in item selection processes for editing and publish the results of the study to a research venue. If you decide to take part, we will ask you to sign a consent form, and you will be given a copy of this consent form to keep.

If you’re interested in participating and have 15-20 minutes to chat (I promise to keep the time!), please either contact me at [] or [] or use this form https://docs.google.com/forms/d/e/1FAIpQLSdmmFHaiB20nK14wrQJgfrA18PtmdagyeRib3xGtvzkdn3Lgw/viewform?usp=sf_link with your choice of the times that work for you.

I’ll follow up with you to figure out what method is the best way for us to connect.

Please contact me if you have any questions or require more information about this project.

Thank you for considering taking part in this research.

Hi Kholoud, my interests are very eclectic, from BG orthodox icons to MIC market codes to GLEI RAL company registries. So I'm not sure what you can learn from that :-) Sorry I won't have time to participate. Send regards to Elena!

Restyling of WikiProject Authority Control

Summary by Epìdosis

I've tried to enact the renewal of the main page, in order to collect ideas from all members of the project: I'm looking forward to hearing your ideas in Wikidata talk:WikiProject Authority control#Renewal of main page. Thank you in advance!

Epìdosis (talkcontribs)

Hi! I've finally succeeded in writing a draft of a possible restyling of the mainpage Wikidata:WikiProject Authority control: it is Wikidata:WikiProject Authority control/Draft. I've tried to insert only basic information about related pages and tools/gadget, in order not to confound new users reaching the page and looking for a little overview; all the useful information collected in the last years would obviously remain accessible in Wikidata:WikiProject Authority control/Archive - I've also added in the fifth tab of Wikidata:VIAF a link to VIAF Games.

Obviously the mainpage can still be expanded, but I would keep it relatively brief, while I think that specific pages about single groups of identifiers would be very useful: as Wikidata:VIAF, also Wikidata:AAT (or a more general Wikidata:Thesaurus) can potentially be created - unfortunately I haven't enough experience to structure such a page, so at the moment I have just inserted a link to Coreference AAT. I wouldn't make them subpages of Wikidata:WikiProject Authority control, in order not to make their title too long and so less easily reachable by users.

Let me know your opinion and thank you in advance for the great work you do!

Vladimir Alexiev (talkcontribs)

hi @Epìdosis: I don't see a lot of the data about VIAF in your new structure (eg the table with counts per source in time), I was only able to find it in archives.

Epìdosis (talkcontribs)

Hi! That's because I had no up-to-date data ready for showing and the old ones referred to many years ago. However, I project to have some good data by the end of the year and I will surely add tables.

Здравствуйте! Пожалуйста, проверьте эту Викидату. Нет ли там ошибок? Всё ли там правильно оформлено? С уважением, Урыл (talk) 10:11, 19 July 2020 (UTC)

Vladimir Alexiev (talkcontribs)

It's pretty good! I just:

  • added two values for "movement"
  • made those instances of "literary movement"
  • changed the "movement" prop constraint to include class "literary movement"
  • changed the encyclopedia URL to use "+" instead of "%20" and Cyrillic instead of encoded chars (IRIs were adopted 15 years ago!)
  • moved the prop "reference URL" to "references" and added prop "URL" as "qualifier"

New OpenRefine reconciliation service

Summary by Vladimir Alexiev


Pintoch (talkcontribs)


Thank you for wearing the {{User loves OpenRefine}} userbox on your user page!

Because the existing Wikidata reconciliation service has had severe performance issues recently, I have created a new one which should be faster and more robust. You can add it to OpenRefine in the reconciliation dialog with the following URL: https://wikidata.reconci.link/en/api (or by replacing en by any other language code).

If you have any issues with this new service, let me know.

Happy reconciling!
