Happy to announce the 2nd edition of our Summer School in Computational Social Science that will take place in the beautiful Villa del Grumello on Lake Como between June 22-26, 2026! *** DEADLINE FOR APPLICATION: February 15, 2026 (firm deadline) *** More details here: css2.lakecomoschool.org

👋🏼 I'm at #EMNLP2025 presenting "The Prompt Makes the Person(a): A Systematic Evaluation of Sociodemographic Persona Prompting for LLMs" 🕑 Thu. Nov 6, 12:30 - 13:30 📍 Findings Session 2, Hall C3

🚨New paper alert🚨 🤔 Ever wondered how the way you write a persona prompt affects how well an LLM simulates people? In our #EMNLP2025 paper, we find that using interview-style persona prompts makes LLM social simulations less biased and more aligned with human opinions. 🧵1/7

Thrilled to talk about how seemingly small decisions in silicon sampling can have a large impact on simulated survey responses 👀 Join us on Oct 29th! 👈

Come join next Wednesday if you want to rant about society's love-hate relationship with LLMs!

👋 #ACL2025NLP 🇦🇹 @marlutz.bsky.social and I are presenting our poster on demographic representativeness of LLMs today! 🕦 10:30-12:00 📍 Hall X5 (board 1 or 14 according to different sources 🧐) Here’s the paper on ACL anthology: aclanthology.org/2025.finding... Drop by!

All the keynote recordings are available now, enjoy! www.youtube.com/playlist?lis...

Chair for Data Science in the Economic and Social Sciences at University of Mannheim having lots of fun at #ic2s2 @janajung.bsky.social @wanlo.bsky.social @indiiigo.bsky.social @jrupprec.bsky.social @maximiliankreutner.bsky.social and Stefano Balietti

Really inspiring keynote by @lauraknelson.bsky.social this morning at #IC2S2 discussing when to model and when to generate societies—among many other themes in computational qualitative research!

Before heading to ACL, I'm excited to be at #IC2S2 this week! 🌞 I'll present a related working paper on validating LLM social simulations at the ABM session on Tuesday (11 AM, Vingen 7): indiiigo.github.io/files/GABM_V... (w/ @wanlo.bsky.social @mstrohm.bsky.social and @janalasser.bsky.social)

Do LLMs represent the people they're supposed simulate or provide personalized assistance to? We review the current literature in our #ACL2025 Findings paper and investigating what researchers conclude about the demographic representativeness of LLMs: osf.io/preprints/so... 1/

LLMs can understand political discourse, but can they actually predict votes of real politicians? Excited to share my work at #IC2S2 this week! I will present my poster on Tuesday between 1:30 and 3:30 p.m.

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) 📊

LLMs can generate synthetic survey responses, e.g. for imputation, but how reliable are they? 📋 At #IC2S2, I'll be sharing our research on the robustness of AI-generated responses to perturbations and if they mirror human survey biases. 🤖 Come by my poster on Tuesday between 1:30 and 3:30 p.m.

Very excited to head to #IC2S2 next week! 🎉 In our project, we tested whether a psychological assessment can measure sexism in LLMs, and found that applying such tools to LLMs is not as straightforward as it seems. Find me and my poster at Poster Session 1 (Tue 12:30-14:30) — hope to see you there

LLMs are trained to produce open-ended responses 📝, but most survey items require closed-ended responses instead 📊 This Wed 11:00–12:30 at #ESRA25, I'll discuss the large impact that Answer Production Methods have on prediction results + share recommendations for methods and parameters. 👈

Day 3 morning sessions: language change and generative AI #ICWSM

Excited to present our paper with @maxpe.bsky.social, @dgarcia.eu, and @mstrohm.bsky.social next week at #ICWSM! ✨ We extend social simulation with LLMs to a longitudinal setting by fine-tuning Temporal Adapters—here's how: 🧵

We're excited to announce #DataFest Germany 2025 at LMU Munich, March 28-30! In this #hackathon, students from diverse study programs compete for the best insights and visualizations from an exclusive dataset within 48 hours. More info: www.datafest.de/home

Ready for another Computational Social Science Starter Pack? Here is number 2! More amazing folks to follow! Many students and the next gen represented! go.bsky.app/GoEyD7d

Sharing my first Computational Social Science starter pack! Will grow with time, feel free to nominate and self nominate! go.bsky.app/CYmRvcK

Repost if you’ve participated in a Summer Institute in Computational Social Science. Let’s get #SICSS Bluesky going!
