Denkmalliste Brandenburg

Nun geht es los, die Denkmal-Items laufen in der Liste der Regelverletzungen auf, da fehlen Koordinaten, Verwaltungseinheiten etc., kannst es dir ja mal angucken. Queryzo (talk) 22:45, 15 December 2016 (UTC)

Dover Passage

Hello Sebastian Wallroth.

You have made a mistake with Q21917769. You have merged a watercourse in Canada with a street in Copenhagen, which just happens to have the same name. --Dannebrog Spy (talk) 10:46, 25 April 2018 (UTC)

Thank you for the hint. --Sebastian Wallroth (talk) 10:49, 25 April 2018 (UTC)

pronunciation audio - probably should be on lexemes

Hi - I notice you've been adding pronunciation audio for a lot of items in Wikidata. Since items represent "concepts" (across any language) rather than words (in a specific language), and the labels may be changed since several words can represent the same concept, it's probably better to move these relations to the corresponding lexeme entries, like organization/organisation (L4333). Check in with Wikidata talk:Lexicographical data if you have any questions about working with lexemes. Thanks for getting all these audio files! ArthurPSmith (talk) 14:52, 17 May 2019 (UTC)

Hi ArthurPSmith, you are absolutely right. The problem is, that the Lingua Libre bot is overloaded. Can you help me with this? I need a list of all lexeme IDs for a given list of words (i.e. Schirm,Schirms,Schirme) where the words can be the value of several lexemes. --Sebastian Wallroth (talk) 16:45, 17 May 2019 (UTC)

I'm not sure quite what you're asking for, but you should be able to do it with the query service. For example, see this query for all lexemes with a form that matches "Schirm", providing some details about the data associated with it (click "Edit SPARQL" from the menu to see the original query syntax).

Problems for item pronunciation

Hallo, Sebastian! I came here to mention Items->Lexeme transition too. Now I just want to show some examples of problems linked with adding pronunciations to items. Mainly they are caused by non-unique correspondence between words and notions.

1. As you understand one item like family name (Q101352) can have different denoting words, just look at label and aliases: "Nachname", "Zuname", "Schreibname", "Geburtsname", "Ehename", "Geschlechtsname". You've just recoreded "Familienname".
2. At hair (Q28472) you've added "Haar" but probably it is more logical to have some plural form like "Haare" or "Haarschaft". Also look at hair (biomaterial) (Q40895177) which I don't understand and head hair (Q336128).
3. Human word like "Regenwürmer" may correspond to several scientific names like Lumbricidae (Q2925555) and earthworm (Q124378). Also
4. Sometimes you are choosing even not a label but alias like in thank you (Q19279214). What about manometer (Q216782)? I cannot even find a word you pronounced among labels and aliases. And do you know what is finimeter (Q12311350)? --Infovarius (talk) 11:04, 21 May 2019 (UTC)

Grüss. --Infovarius (talk) 10:59, 21 May 2019 (UTC)

Hi User:Infovarius, I'm playing around with https://lingualibre.fr/ There you can record files for lexemes as well as for Wikipedia articles. What I did is getting a list of wikidata entries with queries like https://w.wiki/4BV and lingua libre adds the files to the wikidata entries. I hope this answers the question, how and why a add pronounciations files. --Sebastian Wallroth (talk) 11:32, 21 May 2019 (UTC)

Merge of podcast episode (Q61855877) into podcast (Q24634210)

Hi,

I don’t think this merger was a good idea yet:

• podcast episode (Q61855877) was about a podcast episode (eg, 60words is a podcast episode)
• podcast (Q24634210) is about a podcast show (eg, Radiolab (Q2856080) is a podcast show)
• podcast (Q20899) is a weird mix between the above and podcasting as a distribution medium and broadcasting technology (eg, podcasting allows people to subscribe to content using RSS)

Based on this, I don’t think the merge was a good idea. What do you think? Jean-Fred (talk) 10:39, 18 June 2019 (UTC)

I was reading it like this: There are podcasts, consisting of podcast episodes, and podcasting is the producing/hosting of podcasts. This compares to blogs, consisting of blog posts, where blogging is the writing/hosting of blogs. I did the merge having this is my mind. What do you think? --Sebastian Wallroth (talk) 11:33, 18 June 2019 (UTC)

I think we are mostly in agreement here (I like your analogy to blogposts too :)) But what I said above still stands: podcast episode (Q61855877) is a podcast episode, podcast (Q24634210) is a podcast show − hence merging the former into the latter does not work, does it? Jean-Fred (talk) 11:46, 18 June 2019 (UTC)

In that case, please revert the merge. I'll change the German title afterwards. --Sebastian Wallroth (talk) 11:50, 18 June 2019 (UTC)

 Done! :) Jean-Fred (talk) 22:03, 28 June 2019 (UTC)

Next meetup in Berlin

Hello Sebastian and @A ka es:,

I remember that we talked about the Wikidata meetups in Berlin during Wikimania but I can't remember what you told me, I'm sorry. Is there a new one planned soon?

Could you imagine organizing one in October, close to the dates of the WikidataCon (25-26.10)? It could be nice for people who are in Berlin but can't attend to the conference, or for people who are attending but would like a short introduction beforehand.

If you need anything, let me know. Lea Lacroix (WMDE) (talk) 13:38, 26 August 2019 (UTC)

Call for participation in a task-based online experiment

Dear Sebastian Wallroth,

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.

Regards

Preferred Rank

Hi Sebastian Wallroth,

please do not put given names in "Preferred Rank", this will affect infoboxes and categories in other Wikimedia projects. Use "usual forename (Q3409033)" as the qualifier instead. Best regards --HarryNº2 (talk) 17:18, 8 June 2022 (UTC)

Hi HarryNº2, thanks for the advice! I really appreciate that! Greetings from Berlin, --Sebastian Wallroth (talk) 05:23, 9 June 2022 (UTC)

That's great. You can observe the effects on Commons, for example, because then the other names in connection with the infobox are not displayed in the categories. Accordingly, whole name categories are suddenly empty, especially if they only have one name as an entry. Greetings to Berlin, --HarryNº2 (talk) 09:05, 9 June 2022 (UTC)

Invalid Wolfram Language Entity code

Hello. Your recent batch created invalid entries for Wolfram Language entity code (P4839).

See for instance: https://www.wikidata.org/w/index.php?title=Q119477874&oldid=1914904410#P4839

Here's an example evaluation of the entity code in Mathematica, which demonstrates that the code in invalid:

In[1]:= Entity["Surname", "Bayersdörfer"]["Name"]

Out[1]= Missing["UnknownEntity", {"Surname", "Bayersdörfer"}]

Which makes me wonder: Where did you get those codes from? Toni 001 (talk) 08:55, 14 June 2023 (UTC)

Thank you for your message. I created the code following the scheme. I assume that if not yet inthe future the code will work since it is for valid surnames. Sebastian Wallroth (talk) 09:07, 14 June 2023 (UTC)

Die "Else Rauch"

Hallo Sebastian,

einer deiner letzten Nachnamens-Edits ist schief gelaufen: Else Rauch statt Rauch (Q2133058)

Danke für den Hinweis, @U. M. Owen, ich habe es korrigiert. -- Sebastian Wallroth (talk) 16:36, 27 September 2023 (UTC)
