Thrilled to announce CS2Nordics: the First Nordic Conference on Computational Social Science. Copenhagen, September 21-22, 2026.
We invite all CSS researchers in the Nordics as well as in the international research community to submit 2-page abstracts by June 19: nosocss.org/conference.h....
Overview of the three data storytelling conditions and visualizations used in our experiment. The baseline visualizations for each topic are shown in (a) and (b); they served as the baseline for the NO storytelling conditions. Figure (c) shows the written narrative for the Written storytelling condition and Figure (d) shows a single frame from the video used in the Verbal storytelling condition.
Two new NERDS papers: data storytelling visualization, LLMs for complex information needs

New 🚲 preprint! https://arxiv.org/abs/2604.07029
Quality assessment of a country-wide bicycle node network with loop census analysis
We analyzed the new 30000km long Danish #bicycle node network, exploring all 28M round trips in the network up to day-trip length. 🧵
After 17 years of many manuscripts cleaned+submitted to #arxiv, I finally automated and wrote down the process, see: github.com/NERDSITU/research-resour...
Thanks to the amazing Python packages bib_optimizer and arxiv_latex_cleaner.
A two barplots side by side.The left plot shows accuracy of information retrieval (y-axis, ranging from 0 to 100%) across three conditions (No AI, AI, and AI providing wrong answers). The right plot shows self-reported confidence in the answer correctness (y-axis, ranging from 0 to 5) across the same three conditions. Across the two plots, each condition contains two bars: one for users who watched the relevant segment of the video containing the answer to a question, and one for users who did NOT watch the segment. The plot conveys the following messages. 1) In the "No AI" condition, people who did not watch the video provide far less accurate responses. 2) In the "AI" condition, accuracy is high regardless of whether people watched the video or not. 3) in the "AI providing wrong answer" condition, accuracy drops to the minimum values for people who did not check the video. 4) Self-reported confidence in the answers is always high across all conditions, with just a tiny difference between the watched vs. non-watched scenarios
AI can now answer questions about video content, transforming how people consume information on the Web. An experiment with 900+ participants found that AI improves speed and accuracy of retrieval BUT, users become overreliant on AI answers, accepting wrong answers without any loss of confidence.

@mikk.datasci.social.ap.brid.gy just made a super interesting analysis of how much actual voting behaviour is aligned with the political alignment emerging from the online tests that allow you to "make up your mind". As expected the answer is "not so much" and the question then becomes how is
