📢 New preprint: Urban highways are barriers to social ties: arxiv.org/abs/2404.11596 We overlay the highway network with a massive, geolocated online social network, and measure how social ties are impacted by highway segments in 50 US cities. #geospatial #urbanism #segregation

New tool to estimate the level of participation in collective action expressed in natural language. Applied to social media, it can produce large-scale and granular estimates of behavior change wrt collective action. Check it out: github.com/ariannap13/ext… @Carlsbergfondet @ITUkbh

Excited to share the tool @lajello & I built to predict social media participation in collective action! It moves beyond keywords, tracking activism stages across topics. See it in action with climate activism on Reddit 🌱 Check it out: arxiv.org/abs/2501.07368

Our Prisoner's Dilemma work got accepted to @icwsm! Looking forward to next year's edition in Copenhagen. @frapi9

Testing LLMs in Game Theory experiments reveals their moral biases as social agents -- useful to inform alignment. Llama2 playing Prisoner's Dilemma is more forgiving and non-retaliatory than humans, but only when the opponent defects rarely. New preprint: arxiv.org/abs/2406.13605

Seemingly unbiased LLMs exhibit "collective biases" when interacting with other agents. We ought to look at AI biases *within application contexts*, not simply by probing models in isolation. Great collab. with @RELflintashery and @a_baronca @nerdsitu @ITUkbh @Carlsbergfondet

Replying to @a_baronca
We explore how Large Language Models (LLMs) autonomously develop social conventions through interaction, without external programming or centralized coordination. 2/7

A fascinating historical overview of graph mining algorithms at the core of applications from polarization detection to brain activation network generation, with a mention of the legendary @YahooResearch Query Flow Graph. @FrancescoBonchi’s great closing keynote at @asonamcon
