(How) can AI help build better online spaces? ✨ Last week, 16 researchers from 8 institutions gathered in Vienna to explore exactly that question. Between the Christmas markets, the WHAT-IF team discussed how LLMs can power agent-based simulations to tackle online hostility and harmful content 👇

Antico Caffè Torinese, Trieste 🇮🇹 1st visit. Stunning classical café with a booze & cakes focus. Red River & Erdinger on tap, special cocktails and wall of Amaro. The sort of bar you dream of finding in Italy. 🍸 🍻👍

It was a great week at IC2S2 in Norrköping! This community is really something. Today I got to share our findings on tracking engagement with news content on Facebook (check the preprint: arxiv.org/abs/2409.13461 )...and I was lucky enough to do so on the amazing auditorium stage✨️

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: 🧵

A lineplot that shows how scared people in the UK were over time, during the first COVID-19 lockdown. Our method (Llama 3 Temporal Adapters) produces similar estimates of as the survey data gathered by YouGov.

WHAT-IF team members met in Konstanz last week to design the WHAT-IF machine—an agent-based simulation with LLM-driven agents. It models media ecosystems to test 'what if' policy scenarios. Curious how? Read more: what-if-horizon.eu/2025/05/16/o...
