Welcome to Wikidata, Theknightwho!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, don't hesitate to ask on Project chat. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

London GazetteEdit

Do you plan to add more properties or external links to the items for London Gazette issues beyond the four that are currently present? Mahir256 (talk) 01:54, 24 October 2021 (UTC)

Yes. It's unwieldy to add more with the first batch.Theknightwho (talk) 02:11, 24 October 2021 (UTC)
Just for curiosity. When you planning to add more properties and what properties? Thank you so much! --Valerio Bozzolan (talk) 16:28, 24 October 2021 (UTC)
So currently I'm adding all 63,507 issues, and will be adding the PDF links to the official Gazette website such as this. 99% of them going back to issue 1 (in 1665!) are currently uploaded. Longer-term aim is to correctly title and date them, but given the quantity that will be an ongoing process! Theknightwho (talk) 17:30, 24 October 2021 (UTC)
Now that each London Gazette item exists, what's the status on adding more properties to them? Mahir256 (talk) 17:40, 23 November 2021 (UTC)
I've run into some issues in determining which issues have been uploaded and which haven't - I will try to make sure this is sorted by the end of the year, but it's slow going due to manual checking. Theknightwho (talk) 17:29, 27 November 2021 (UTC)
Any updates on this? (There are at least 1500 references to just "The London Gazette" that could be migrated to the items you've created.) Mahir256 (talk) 01:48, 4 February 2022 (UTC)
I have added URLs to those issues that have them (approximately 50,000 iirc). The dates will have to be done manually and will likely take hundreds of hours, but I think having an external link where one is available is probably alright for now? Theknightwho (talk) 16:29, 4 February 2022 (UTC)


Hello. I don't know where the general discussion can be, so let's try here.

  1. How do you distinguish "letter" and "symbol"? Isn't beta (Q14382) an (indirect) instance of symbol alread? Why can't there be properties like these + TeX string (P1993)?
  2. What's the relation between (Q87524463) and radical sign (Q11536248)? Aren't they both "symbol" of square root (Q134237)? Should they be merged (like you've done with Q3490724+Q87496146)?
  3. Why do you use (e.g. for intersection (Q185837)) depicted by (P1299) and not notation (P913)? I'd prefer the latter for mathematical operators...
  4. The other problem with Q3490724+Q87496146 is that
    ⟨ less-than sign (Q87496146)      ⟩ has use (P366)   ⟨ Q100606170      ⟩
    while less-than sign (Q3490724) is semantically only for relation "less than", no? Same with greater-than sign (Q3490717).
  5. How can one Unicode character be depicted by (P1299) the other?
  6. May be you know how to find (query) all ASCII characters? --Infovarius (talk) 11:08, 18 November 2021 (UTC)
  • Hi - I think that's a good idea. My recent merges weren't really intended to be comprehensive, as I was just clearing things up anything that used the HTML entity (P4575) property before adding it en masse. Obviously in the long-term we'll want things to be consistent.
    1. My approach with Latin and Greek letters is that we need to have an item for the letter itself (e.g. the concept of the letter Beta), but the issue is that we also need items for uppercase and lowercase Beta as neither one is the "default" that can claim to be the true Beta. They're both instance of (P31) beta (Q14382), though I haven't got around to editing that yet. This is different from, say, letters that only have one character which represents them (i.e. the character is the letter), or where one is clearly a variant (e.g. a rare capitalisation, or a circle around etc.). Strictly speaking, the properties I removed weren't properties of beta (Q14382), but properties of particular instances of beta (Q14382) (i.e. they were properties of uppercase Beta and lowercase Beta). I know they had the qualifier applies to part (P518), but I'm not sure that it was being used correctly - they're instances, not parts of - and it would be good to avoid duplication to prevent divergence.
    2. I see no issue merging (Q87524463) into radical sign (Q11536248), agreed.
    3. I used depicted by (P1299) as I was doing that for anything where I was distinguishing the concept from the representation, but notation (P913) does seem better for mathematical operators, yes.
    4. So the question is whether less-than sign (Q3490724) and Q100606170 are semantically different (i.e. could they be used in the same document in different ways and be seen as different characters and not merely different uses?). Obviously a character can represent multiple concepts, but just because (for example) exclamation mark (Q166764) can represent emphasis (Q65044042) and factorial (Q120976), doesn't mean that they each have their own character. They're both exclamation mark (Q166764), being used in different ways.
    5. percent sign (Q7559698) is the percent sign, while (Q87544541) and (Q87544197) are variants (fullwidth and small, respectively). The latter two depict the former, which is a bit different from letters.
    6. I don't have much experience with querying, sorry. We seem to be missing a bunch of ASCII control characters - I haven't been able to find items for a lot of them. Theknightwho (talk) 16:12, 18 November 2021 (UTC)

Call for participation in a task-based online experimentEdit

Dear Theknightwho,

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, in which I have developed a personalised recommender system that suggests Wikidata items for the editors based on their past edits. I am collaborating on this project with Elena Simperl and Miaojing Shi.

I am inviting you to a task-based study that will ask you to provide your judgments about the relevance of the items suggested by our system based on your previous edits. Participation is completely voluntary, and your cooperation will enable us to evaluate the accuracy of the recommender system in suggesting relevant items to you. We will analyse the results anonymised, and they will be published to a research venue.

The study will start in late January 2022 or early February 2022, and it should take no more than 30 minutes. If you agree to participate in this study, please either contact me at kholoud.alghamdi@kcl.ac.uk or use this form https://docs.google.com/forms/d/e/1FAIpQLSees9WzFXR0Vl3mHLkZCaByeFHRrBy51kBca53euq9nt3XWog/viewform?usp=sf_link I will contact you with the link to start the study.

For more information about the study, please read this post: https://www.wikidata.org/wiki/User:Kholoudsaa In case you have further questions or require more information, don't hesitate to contact me through my mentioned email.

Thank you for considering taking part in this research.

The London GazetteEdit

Hello, you may find useful the item issue of the London Gazette (Q111011066) to be used as instance of the items of the single issues of the London Gazette. -- Blackcat   18:06, 24 February 2022 (UTC)
