Und wieder ein neues Wort gelernt: "Homologierung", auch Homologation. Die offizielle Genehmigung oder Zulassung eines Produkts durch eine zuständige Behörde. Danke orf.at @juortner.bsky.social. sport.orf.at/stories/3147...

New academic year, new team photo! Hello from the Computational Social Science group @tum.de @hfp.tum.de @School of Social Sciences and Technology.

Welcome to another week of international meeting coordination drama! Europe has concluded "Summer Time", while the US will stay another week in Day Light Saving time.

'10 Regeln für die Digitale Welt' sind nun "in der Welt"! 😊 Ich durfte sie in einer spannenden Gruppe mitdefinieren, u.a. mit @jurgenpfeffer.bsky.social und @paulnemitz.bsky.social. Hier eine der vielen News dazu: news.vm.uni-freiburg.de/de/newsarchi... Kommentare sind sehr willkommen! 1/2

Ever wanted to pan through the latent🌌 space of TikTok videos? Made using the amazing toponymy and datamapplot from @lelandmcinnes.bsky.social and data from mine and @jurgenpfeffer.bsky.social 's first complete TikTok slice. link below

Bremen, it was a pleasure! Thank you for the workshop on our book project on why the "data revolution" needs qualitative research and the keynote of @jurgenpfeffer.bsky.social

In the updated version, we can now estimate for the one day: - a total of 269 million posts produced - 176 years of videos uploaded - ~1/4 of videos gets deleted New version: www.arxiv.org/pdf/2504.13279 PS: Thanks for all your comments and questions. :)

Heute zu Gast: @jurgenpfeffer.bsky.social von der @tum.de. In seiner #LIfBiLecture drehte sich alles um Herausforderungen beim Umgang mit neuen #Datenquellen, die vor allem auf #digitalen #Technologien beruhen. Für einige Forschende geht's jetzt noch in den persönlichen Austausch.

Researchers reckon they've managed to reverse-engineer access to a single day on TikTok. Among the findings? One in five videos features kids, and uploads at zero seconds past the minute do better. By me for @fastcompany.com www.fastcompany.com/91323722/ins...

Humbled to find via @JurgenPfeffer that dataViz of interlocking corporate directories predates my take by >130 yrs:

Have you ever asked yourself about the overall extent of TikTok? Here some numbers from "Just Another Hour on TikTok" - Great compliment to @bendavidsteel.bsky.social for this data collection effort! w/ @miriamschirmer.bsky.social & Derek Ruths arxiv.org/abs/2504.13279

Hallo @faznet.bsky.social -Ich höre Eure Tech/KI Artikel in der Regel und denke, es muss irgendwie möglich sein, dass Eure Text-to-Speech Software das Wort "Daten" korrekt ausspricht. Aktuell ist es ein englisches "Daitn". Ich habe gut Erfahrungen mit Wörter im Text ersetzen, versucht mal "Daaten".

Paper alert! 🚨 We investigate Bluesky’s journey from an invitation only platform with a few thousands of users to reaching 30 million users in terms of user activity and network growth. 📄 Full paper: arxiv.org/abs/2504.12902 💻 Codes: github.com/osome-iu/ris... 💾 Dataset: zenodo.org/records/1506...

I guess the question of learning something becomes hard when the correct solution is only a click away. "... nearly half (~47%) of student-AI conversations were Direct—that is, seeking answers or content with minimal engagement. ..." www.anthropic.com/news/anthrop...

Wir sammeln alle Wissenschaftler:innen und wissenschaftliche Institutionen, die auf Bluesky sind. Falls wir jemanden oder eine etwas vergessen haben, schreibt uns!

Ein Hoch dem orf.at Mut mit dem Konjunktiv II auch an grammatikalische Orte zu gehen, die die meisten Menschen meiden würden. PS: Dennoch würde ich gerne auch mal eine "tadad" lesen. :) @juortner.bsky.social

Every time I am on X at the moment, I get several negative campaign ads for the German election from paid for reach campaigns from new non-German language accounts with less than 10 followers.

That’s interesting: a random hater can push his message on X to ~30k views and has a little commercial (Werbung) Label. I‘m wondering who pays for these campaigns…

Correct. If the birthdate field contains corrupt or mismatched data, it defaults to 1875-05-20, which serves as a flag. May 20, 1875, is the day the international standards and metrics treaty was signed. Everything is a conspiracy when you don’t know how anything works.

This is the playbook. Find single cases of possible errors or fraud in the system as argument for destroying the entire system. Automation will then be used to take away people‘s rights. Read about it in „Automating Inequality“ by Virginia Eubanks.

I finished my PhD in 1999 IES funded my career for nearly two decades I will be fine I worry about the young scholars whose work is being knee-capped

I guess using generative AI for education is the future. ;)

I guess the AI-boom is not so self-confident after all ... a little open language model gets released and Nvidia is losing close to 20% in value ($500 billions) in a couple of hours. #AIBubble #DeepSeek

Nice piece on our latest article! :)

Hier genau auf den unteren Teil der Abbildung schauen (Achtung: log-Darstellung): Die Reichweite verzehnfacht sich hier plötzlich!

Roughly 6,000 readers answered our poll, with many declaring that Bluesky was nicer, kinder and less antagonistic to science than X https://go.nature.com/42tH8Ai

Echt jetzt, Microsoft...?

It seems that ChatGPT has recently become more utilitarian! "...we can show clear evidence for a shift in ethical stances in recent model developments." #ethics #LLMs papers.ssrn.com/sol3/papers....

Does anybody have positive experience with the pre-print service Research Square (Springer Nature)? After three weeks, the article is still under initial screening and they are trying hard to sell me their language quality improvement service - this feels a bit like a scam.

Sure, I could say some things about social media and politics right now. It’s my job and everything. Instead I ran outside in the freezing temps to join my neighbors who are setting off their leftover stock of New Year’s fireworks. DC needs something to celebrate. #Commanders 🧨 🎇
