On last day of #aoir2025 @lionw.bsky.social presents our @weizenbauminstitut.bsky.social work on TikTok data donation from the 2025 German Federal Election - only 5% of content was political and the Left party could capitalize most in reaching voters of other parties with their content on TT.

#DigitalNewsDynamics research group present #datadonationsymposium2025 @lkseiling.bsky.social and Quentin Bukold on an Ontology for digital trace data, me on data donation behavior, and @dscheykopp.bsky.social on our experience with #deinfeeddeinewahl.

#datadonationsymposium2025 @lmumuenchen.bsky.social @dscheykopp.bsky.social @lboeschoten.bsky.social @antmandan.bsky.social On the myth of the need for representative samples, public partnership recruiting, the value of specialty samples, and a value proposition to the public as an incentive.

Has anyone else recently received a reply from the #tiktok research API support team after just 6 months? They transitioned to a new communication system. God knows how that company is still running if they could not communicate for 6 months, or could they 👀. #capitalistprioritiesarewild

Goodbye Zürich once again. It was an absolute pleasure to engage with the participating scholars on visual communication at the Computational Visual Communication Research Symposium organized beautifully by Meg Jing Zeng. Take away - LLMs are too good and convenient to avoid them ...

I put together a list of scholars speaking at the Computational Visual Media Research Symposium in Zürich today. Maybe interesting for some of you. Let me know if I missed you/isn't find you! bsky.app/profile/did:...

Really excited to also present this work at #IC2S2 next week in Norrköping! 🎉 I'd love to discuss how to produce LLM survey responses at my poster on Wed at 13:30 (Poster Session 2, Poster ID 68) 📊

Loving @ic2s2.bsky.social , but I wonder if we're asking the right questions. Is "How can I outsource this task to a proprietary, black box, resource-intensive, often un-validated LLM?" when fit-for-purpose classifiers abound a computational a computational research question? Or even scientific?

@ic2s2.bsky.social Thought provoking keynote by Arnout van de Rijt! What's a better proxy for economic success over lifetime - wage rank or wealth? Wealth might show the exact opposite results, with wage being rather another (un)lucky event instead of an outcome of the other (un)lucky events.

Poster presentation at #ic2s2 done. Inspiring talks and a sore throat come hand in hand. Looking forward to the remaining days!

"From Isolation to Extremism: Radicalization in the Manosphere." We spoke to @lionw.bsky.social & Linda Coufal about how extremist views take hold and spread within digital communities: 🔗 t1p.de/sqii5 #DigitalExtremism #OnlineHate #PlatformAccountability #Misogyny

#ic2s2 getting started! A grand hall for a grand opening. Unsurprisingly LLMs make up their own strong topic among conference presentations. But amazing to see that CSS still maintains an identity and topical diversity beyond that! @ic2s2.bsky.social

A curious way to make use of so called AI for a change! Participation encouraged!

#IC2S2: Join me tomorrow at my poster on how to measure information use on social media in #DataDonations! 🌐 Survey development, panel study, digital trace data, TikTok, and multimodal classification—it has it all! 📢 Perhaps we can even debunk the myth that the youth aren't informed no more 👀.

„Wer beim Forschungsdatenzugang jetzt liefern muss” – @lkseiling.bsky.social, @dscheykopp.bsky.social, @claesdevreese.bsky.social & @ulrikeklinger.bsky.social heute im @tspbackground.bsky.social: 🔗 t1p.de/zf6pa ⬅️ #dsa @dsa40collaboratory.bsky.social

📢 Big news for platform researchers across Europe and beyond: Today, the @ec.europa.eu adopted the Delegated Act for Article 40 of the Digital Services Act (DSA) – a long-anticipated milestone enabling researchers to request access to non-public platform data under Article 40.4.

Stellar panel on data donations at #ica25 @lionw.bsky.social presenting on across platform sample biases, Yangliu Fan @weizenbauminstitut.bsky.social on sequence mining in digital trace data, and @ernesto-deleon.com on tailored recruitment messages. Full room shows how important #datadonation is

Join us and be enlightened!

How or why does #political content spread on #TikTok? Is there a large supply by political actors, is there a high demand by users for political content or is that content preferred by the platform algorithms? Weizenbaum researcher Felix Gaisbauer takes the issue apart at #WIConf2025

Axel Bruns @snurb.info talks at #WIConf2025 about #SocialMedia Practice Mapping in #ClimateChange debates in Australia, from climate policy advocates to the local fire departments.

Felix Gaisbauer presenting first insights into political content suggested too and seen by actual German users around the German election earlier this year. Debunking assumptions of asymmetrical algorithmic curation on #tiktok in recent years. #WIConf2025 @weizenbauminstitut.bsky.social

The second day of #WIConf2025 opens with a talk by @victosilva.bsky.social on the impacts of public #digital #infrastructure on civil society. Part of a panel on „Infrastructure and Market Dynamics“, hosted by @lionw.bsky.social

@weizenbauminstitut.bsky.social #WIconf2025 has started and lunch is about to be served oO!

New paper out! What impact had the first wave of COVID-19 lockdowns on radicalization processes in the incel community? Find out now, the answer may suprise you! -> doi.org/10.1177/1461...

Teilen - gerade auch außerhalb der Bluesky Bubble :)))

Ihr nutzt TikTok? Es wäre super hilfreich, wenn ihre eure Daten für ein Forschungs- und Datenjournalismus-Projekt spendet: Wir wollen wissen, wie viel Wahlkampf im Feed landet. Alle Infos, auch was genau mit den Daten passiert, im Text.

Spende TikTok-Daten, bekomme Politik-Sofortanalyse - nach diesem Prinzip starten wir ein Rechercheprojekt mit @weizenbauminstitut.bsky.social @brdata.bsky.social und anderen. Weitersagen und mitmachen!

🗳️Soziale Netzwerke beeinflussen, welche Inhalte Nutzer:innen sehen – doch was bedeutet das für Wahlen? Das neues Forschungsprojekt „Dein Feed, Deine Wahl“ untersucht, wie politische Inhalte auf TikTok auftauchen. Mehr Infos und das Interview mit Lion Wedel: www.weizenbaum-institut.de/news/detail/...

Our new project is finally out! dein-feed-deine-wahl.de Share, like, and participate. Donate your data to get a personalized report on political party activities in your feed!

So sieht's aus! Wir freuen uns auf euch!

#servicepost The #tiktok research API finally returns data for the week before the Trump inauguration... How that data looks like? tba

The TikTok Research API continues to fail in providing any data, no matter the query, on videos published between (incl.) the 13th and 21th of January. Across APIs, researchers, and institutes in Europe. Tiktok data access is a farce. #dsa #eu #tiktok

Chipping in, to the #ica25 celebrations! Bitter sweet but tbf I get it - anything but my dissertation paper got accepted lol. Looking forward to projects led by @jonathanhendrickx.bsky.social , @atmayer.bsky.social , Yangliu Fan, and my humble self to be presented! See you in Denver 🔥 🐸

What an exciting workshop on Visual Aspects of Political Communication and Digital Platforms, I had the pleasure to host at the Collegium Helveticum. Welcoming @franzimarquart.bsky.social for her keynote on Visual Velocity & researches from @weizenbauminstitut.bsky.social and UZH. Really inspiring!

Grand final of an exciting and inspiring workshop on visual political communication! @Collegium Helveticum, Zürich. It was a pleasure to be part of this. Thanks to @dscheykopp.bsky.social for organizing this! @weizenbauminstitut.bsky.social

Drone demo presentation in the office? Nothing is impossible at UZH Zurich oO.

Want to collect TikTok data but need help figuring out where to start? Look no further but here 👀: methodslab.weizenbaum-institut.de/2024/11/12/t...

We finally published our study on information categories for risk communication in data processing! Read the full paper here: ieeexplore.ieee.org/document/104... (open access) tl;dr: youtu.be/864gq-D6H7s So, what did we research and why? 🧵 @weizenbauminstitut.bsky.social

Save the Date! I'm excited to be part of organizing this year's WiDS Rhine-Neckar event, focusing on Smart Cities. It will be held online on June 24th, and registration will open shortly. Stay tuned for more details!
