RE: https://curia.social-network.europa.eu/@Curia/116758852644484436
Well. A lot of digital rights lawyers seem very excited about this ruling from the Court of Justice today - in particular, the final paragraph 122:
⚡️a website that controls what viewers see via an algorithm is liable for the content⚡️
Full judgment (in French): https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex:62024CJ0188

A Job I Like or a Job I Can Get: Designing Job #RecommenderSystems Using Field Experiments https://d.repec.org/n?u=RePEc:arx:papers:2603.21699&r=&r=exp
"… welfare-optimal RSs rank vacancies by an expected-surplus index, and shows why rankings based solely on utility, #hiring probabilities, or observed application behavior are generically suboptimal
… Algorithms informed by the model-implied optimal ranking substantially outperform existing approaches and perform close to the welfare-optimal benchmark.While the joint application-and-hiring probability is not welfare-optimal in theory, it emerges as a strong empirical benchmark in our setting. This result is structural rather than algorithmic: application probabilities are empirically small and remain so even under recommendation rules designed to stimulate applications
… rankings based solely on application behavior are theoretically fragile
… Machine-learning tools can substantially improve matching outcomes, but only when embedded in a framework that defines the economic objective and disciplines behavioral assumptions with experimental evidence. Without such a framework, RSs optimized for observable behaviors may perform well on predictive metrics yet remain misaligned with welfare-relevant outcomes."

Two teams from LIPN will present their joined work at IPMU 2026 👏.
Congratulations to Amal Beldi and Louenas Bounia for their work on Uncertainty-Aware Contextual Recommendation under Possible Worlds Semantics!
This paper proposes a probabilistic framework for uncertainty-aware contextual recommendation grounded in probabilistic database semantics.

Future recommendation infrastructures must integrate evaluation protocols, fairness metrics, and reproducible pipelines as first-class design principles—not afterthoughts.
The paper “WarpRec” proposes a framework that unifies academic rigor with industrial-scale recommendation systems, aiming for responsibility, reproducibility, and efficiency at scale.

Paige Saunders @paige (rather than Dawn Walker @dawn as I erroneously wrote earlier!) has this great video, 'We Have An Algorithm Problem' at https://video.fedihost.co/w/a1522517-704e-44a3-aa0e-5c4e7d49e7d1, where he says that fediverse users' suspicion of algorithms is completely warranted, but now that we have been able to opt out of algorithmic content where we had zero agency, we need a conversation about what it means to opt in with algorithms under our own control.

"Banning #socialmedia for young people will ignore the incredibly harmful societal effects of modern social media for most of the population…
The most immediate solution is to ban companies from using #recommendersystems entirely (outside a few specific cases); that would restore our freedom to choose what we see online, and at least pause our descent into the years-long spiral towards increased extremism, misinformation, social media addiction & polarisation."

Without dopamine optimising suggestions I am saving so much time! Highly recommended :D

NEW STUDY OUT IN IC&S
Putting #FilterBubble Effects to the Test
In an experimental survey study with real #news #recommendersystems (#NRS), we find **limited** support for #polarization effects of #algorithms inducing "filter bubble" like information environments.
Data also show how balanced algorithms may promote #depolarization.

"…recommender systems show different jobs to identical male & female job seekers, though most of the jobs overlap
…women are steered towards jobs that pay less, are in smaller firms, & require less experience, suggesting a lower rank in firms’ hierarchies

The next round of our Algorithmic Accountability Reporting Fellowship is just around the corner! 🚀
Got questions? Join us for a Q&A session with Naiara Bellio from our Journalism team TODAY at 6 pm: https://algorithmwatch.org/en/apply-fellowship/
In this round, we're diving deep into the political economy of AI, exploring crucial topics like #generativeAI and #recommenderSystems. Our aim? To unravel the AI value chain and its far-reaching impact on society, particularly on specific population groups.
