Key Finding: Generative AI broadens participation and facilitates user interaction, but risks saturating platforms with perceived lower-quality, generic content, leading to diminishing authenticity, trust, and diversity of perspectives. Check out the explainer: ai-research.andersgiovanni.com

No fewer than three people were needed to cover all the aspects of our dialogue simulation paper. Thanks for the interest — check out the preprint. Link in Dustin’s post. @dustinbwright.com @ic2s2.bsky.social #ic2s2

#ic2s2 I’ll have a poster (#21) today on 𝐭𝐡𝐞 𝐢𝐦𝐩𝐚𝐜𝐭 𝐨𝐟 𝐠𝐞𝐧𝐞𝐫𝐚𝐭𝐢𝐯𝐞 𝐀𝐈 𝐨𝐧 𝐬𝐨𝐜𝐢𝐚𝐥 𝐦𝐞𝐝𝐢𝐚 ✌🏼

It’s a wrap ✨ One more edition of #icwsm is over. Amazing research outputs, insightful conversations and many new, exciting ideas! Thanks to all the organizers, chairs and volunteers who made the event possible, and to all the participants for making ICWSM 2025 a memorable edition 🇩🇰

Excellent story in @theverge.com today on the impact of AI-Mediated Communication. Quotes me but the best line is the closer from the writer, Sara Parker.

Testing LLMs in the Prisoner’s Dilemma to reveal their moral biases. LLMs can defect often but become more forgiving and less retaliatory than humans when opponents are mostly cooperative. Nicolò Fontana at #ICWSM. w @frapierri.bsky.social Paper: ojs.aaai.org/index.php/IC...

Detecting participation in collective action from social media text. Great tool to build large-scale ground truth about collective engagement online. Fantastic work by @ariannapera.bsky.social at #ICWSM. Paper: ojs.aaai.org/index.php/IC... Code: github.com/ariannap13/e...

Fresh evidence agreeing w/ one of our studies mentioned in the story above, from @danielmromero.bsky.social @davidjurgens.bsky.social @lajello.bsky.social "AI-tools increase user engagement and volume of generated content, but... decrease the perceived quality and authenticity of discussion"

AI-assisted social media posting increases the volume of content people produce. However, that content is perceived as lower quality than purely human-generated posts. A dangerous spiral that may flood social media with low-quality content. Results from a controlled study: arxiv.org/abs/2506.14295

I'll be at #ICWSM 2025 next week to present our paper about Bluesky Starter Packs. For the occasion, I've created a Starter Pack with all the organizers, speakers, and authors of this year I could find on Bluesky! Link: go.bsky.app/GDkQ3y7 Let me know if I missed anyone!

What actually happens on social media when users get access to integrated AI?🤖 In our new preprint, we present a controlled experiment testing the impact of generative AI (4 treatments + control) on a social media platform, using a representative sample of nearly 700 U.S. participants.

"Urban Highways Are Barriers to Social Ties" out on PNAS! The 1st large-scale measure of how highways weaken social connections between the communities they separate. This barrier effect is strong in the 50 largest US cities--especially for low-income Black communities. www.pnas.org/doi/10.1073/...

The second edition of my Atlas for the Aspiring Network Scientist is out! You should check it out if you like to learn about network science or graph neural networks. Check out the blog post I wrote to present it: https://www.michelecoscia.com/?p=2393

Happy 2025! 🎉 📅 The ICWSM submission deadline is just two weeks away (Jan 15)! Check the page limit here: www.icwsm.org/2025/submit/... Don't forget the mandatory Ethics Checklist and that optional Appendices don’t count toward the limit

My TEDx talk about people-centered AI and mental health is finally live! This was a really big accomplishment with a lot of work, and I'm proud of it, esp in light of conversations on social media and mental health we're having today - www.youtube.com/watch?v=H30b...

What a nice blogpost from Hugging Face (@hf.co) on test-time "thinking" with open-source models, showing how a 1B model can beat an 8B and how a 3B can beat a 70B with the right strategies. It also gives a great overview of different approaches - check it out! 🚀 huggingface.co/spaces/Huggi...

📢 New preprint: #network analysis of the #danish #Bicycle infrastructure 🚲🕸️ -Yes, a *whole country's* bike network analyzed, led by @ane. See the 37-page paper: https://arxiv.org/abs/2412.06083 Main results: Good bikeability in cities, some regional […] [Original post on datasci.social]

Quick tip: use uv to handle your envs, packages, and projects. I've used poetry for quite some time now, it's just pretty convenient even though it is slow. uv is, as they say on their website, "An extremely fast Python package and project manager" - this is true. 💨 You're welcome!👏🏼

Podcasts are a popular medium, but data for computational research is limited! We introduce the Structured Podcast Research Corpus (SPoRC - huggingface.co/datasets/bli...), a large, multimodal dataset of English podcasts 🧵 arxiv.org/abs/2411.07892

It's great to see the massive wave of people coming to 🦋. Here's my first stab at a Computational Social Science starter pack: go.bsky.app/2m6iQ68 Go check out similar lists to bootstrap your network: bsky.app/starter-pack... bsky.app/starter-pack... Wonder if these lists could be merged somehow..

Do this, really! So helpful 👌
