We have an open PhD position on Fair Social Network Analysis (focused on method development but also on integrating social theory and real data analysis). Please consider applying if this is something of your interest or share this to potentially interested candidates. uuinfolab.github.io/joinus/

We welcome @anmen.bsky.social as a new postdoctoral researcher at Uppsala University, Dept. of Information Technology, and as a new member of the InfoLab.

Congratulations to our @dvladek.bsky.social for being appointed Docent in Computer Science!

🚨 New paper out! 🚨 🔗 arxiv.org/abs/2509.21092 [read comments for more!] Special thanks to my co-authors @dvladek.bsky.social and Alessio Gandelli from @uuinfolab.bsky.social ! #ComputationalSocialScience #OnlineSocialNetworks @arxiv-cs-si.bsky.social

Our new study provides the first large-scale look at how collective action is expressed in spoken digital discourse, using #BlackLivesMatter as a case study. Many thanks to @ariannapera.bsky.social @dvladek.bsky.social @lajello.bsky.social for the collab Check it out: arxiv.org/abs/2509.13197

Last week we have been at the International Tutorial and Workshop on Artificial Intelligence, Data Analytics and Democracy to present our work on visual political communication. Thanks to the organisers for the invitation! @susanly.bsky.social @lorenzo-mannocci.bsky.social aidem2025.isti.cnr.it

Our article on population-scale networks of social opportunities constructed from administrative data is now available online: www.nature.com/articles/s41....

This week we are at the Comp. Visual Media Research Symposium in Zurich, with @matiaspiqueras.bsky.social presenting his work on visual structured topic modelling. @lrossi.bsky.social is also presenting recent results based on joint work on LLMs and social image clustering (osf.io/preprints/so...).

@uuinfolab.bsky.social @ #ic2s2

We welcome Dariia Puhach as a new research assistant at the lab. Dariia will work as part of the PolarVis project to develop a method for the computational analysis of visual climate narratives.

This week many of us are in Norrköping for the International Conference on Computational Social Science. In the thread, a list of our presentations. #ic2s2

Two PolarVis presentations this week: (1) on the (mis)uses of VLLMs for analysing climate change visuals, today at the CCVision Network Meeting, and (2) on methods for longitudinal coordination detection applied to PolarVis data, tomorrow at SunBelt. @lrossi.bsky.social @matmagnani.bsky.social

This week we are at #ICWSM, with @giorgospanay.bsky.social talking about representational fairness in graph community detection.

This week we are at SunBelt, in Paris - starting today with a tutorial on multiplex social network analysis.
