Social media feeds today are optimized for engagement, often leading to misalignment between users' intentions and technology use. In a new paper, we introduce Bonsai, a tool to create feeds based on stated preferences, rather than predicted engagement. arxiv.org/abs/2509.10776

Last day of #ACL2025NLP but there's still lots to do: attend the #WikiNLP workshop, where we explore how NLP and wikipedia can help each other! We have amazing keynotes, discussions with Wikipedia editors, a panel + posters! Details: meta.wikimedia.org/wiki/NLP_for... Join us in room 2.31!

Excited to co-organize the Bridging Human and LLM Annotations for Social Science tutorial at #ic2s2 tomorrow! Join us at 1:30pm CEST to learn how to combine Qualtrics+Prolific, MTurk, & LLMs for automated annotation and valid estimates. Code&materials: github.com/kristinaglig...

#ICWSM @icwsm.bsky.social would be nothing without its community. Here are some of the heroes who work hard to guarantee that authors receive useful reviews: @aldayelabeer.bsky.social @chibold.bsky.social @lespin.bsky.social @elaragon.bsky.social @shrutiphadke.bsky.social @tiziano.bsky.social

Looking forward to giving a tutorial on Social Media Feed Ranking Algorithms with @tiziano.bsky.social at @icwsm.bsky.social today! Come join us at AAU, Room 2.1.083.

I'm so excited to join the CS department at Johns Hopkins University (@jhu.edu) as an Assistant Professor! I'm looking for students interested in social computing, HCI, and AI—especially around designing better online systems in the age of LLMs. Come work with me! piccardi.me

I'm excited to announce that I’ll be joining the Computer Science department at Johns Hopkins as an Assistant Professor this Fall! I’ll be working on large language models, computational social science, and AI & society—and will be recruiting PhD students. Apply to work with me!

100 Years of Engineering @ Stanford!

Deadline today! 🚨 Join us at the 2nd WikiNLP Workshop on NLP for Wikipedia, co-located with #ACL2025 in Vienna. We welcome both in-person and virtual attendees! 🗓️ Submission deadline: April 30 🔗 Details: w.wiki/CumQ

New funding opportunity for Wikimedia-related research! Grants up to $150K available. Apply by April 16th: meta.wikimedia.org/wiki/Grants:...

2⃣ seminars coming up on Thursday with @tiziano.bsky.social and @uthsav.bsky.social! Check them out at bit.ly/3Fv5n7C and bit.ly/3FssGPr

Book announcement: with Melissa Valentine, we are publishing "Flash Teams: Leading the Future of AI-Enhanced, On-Demand Work." It's a leadership book synthesizing a decade of Stanford research on how computing, online platforms, and AI reshape teamwork. Coming October from @mitpress.bsky.social!

Thanks to @tilmanbayer.bsky.social for covering our work on Wikipedia readership in the latest Wikimedia Research newsletter! ➡️ arxiv.org/abs/2501.00939

🤖🍲 What can LLMs do for sustainable food? 🤖🍲 We collaborated with domain experts (food scientists and chefs) to define a typology of food design and prediction tasks. LLMs can assist in food and menu development, saving food scientists' time and reducing emissions! URL: bit.ly/3ERJbUV

The call for papers for the second edition of the #WikiNLP workshop at @aclmeeting.bsky.social is out! We welcome contributions on #NLProc + Wikimedia, especially on datasets, and ideas to advance its mission. More details: meta.wikimedia.org/wiki/NLP_for...

📢 Call for #ICWSM2025 workshop proposals! icwsm.org/2025/submit/... All Web + social media topics are welcome! Especially emerging approaches and task areas, bridging gaps between the social sciences and computing, and elucidating results of exploratory research. Due Fri Jan 24th AoE!

How do people *really* read Wikipedia? 📖 👀 We explored how readers navigate, fall into rabbit holes, and engage with information in a chapter for the ‘Handbook of Computational Social Science,’ edited by @tahayasseri.bsky.social. Stay tuned for the full book! 📚 Preprint: arxiv.org/abs/2501.00939

Thrilled to share that the Handbook of Computational Social Science manuscript was finally submitted to the publisher in full! Huge thanks to all the authors and reviewers who made this possible. Check out the Table of Contents!

Weekend exercise: testing the Bluesky firehose. Who doesn't need a real-time dashboard to track EVERY emoji in messages? 😭, 😂, 🤣, ❤️ are topping the leaderboard! feeds.feedwizard.org (counters just started)

New @acm-cscw.bsky.social paper, new content moderation paradigm. Post Guidance lets moderators prevent rule-breaking by triggering interventions as users write posts! We implemented PG on Reddit and tested it in a massive field experiment (n=97k). It became a feature! arxiv.org/abs/2411.16814

New paper: Do social media algorithms shape affective polarization? We ran a field experiment on X/Twitter (N=1,256) using LLMs to rerank content in real-time, adjusting exposure to polarizing posts. Result: Algorithmic ranking impacts feelings toward the political outgroup! 🧵⬇️
