Boiling here at home in Cyprus but I put the finishing touches a couple of days ago on this preprint: What Does 'Human-Centred AI' Mean? doi.org/10.48550/arX...

Wherein I analyse HCAI & demonstrate through 3 triplets my new tripartite definition of AI (Table 1) that properly centres the human. 1/n

Lastly, we conduct a small-scale OOD exploratory evaluation using European political speeches. RoBERTa’s performance severely drops due to overfitting, while Qwen 3 and Gemini 2.5 achieve comparable results and outperform RoBERTa by ~10%, showcasing robustness across domains. 4/5

Our analysis of a large collection of Trump’s campaign speeches (2015 -2025) reveals: (a) a decline in populist rhetoric over time, (b) no meaningful difference in populist intensity between swing/non-swing states, and (c) populism is concentrated towards the end of a speech. 3/5

We examine whether LLMs can identify and classify fine-grained forms of populism, a complex and contested concept in both academic and media debates. To this end, we curate and release datasets and evaluate a range of large language models across multiple prompting paradigms. 2/5

My research will center on three key areas: (a) NLP for Political Science, (b) AI & Society, beginning with critical challenges in AI alignment, and (c) NLP for Law.

Reach out if you're interested in any of the above πŸ‘†
I'm glad to share more and listen to your ideas πŸ˜‡ 2/2

I’m thrilled to share that, starting today, I’ve officially rejoined the University of Copenhagen as an Assistant Professor.

I'm looking forward to new projects and collaborations, with a focus on expanding my research into computational social science. A new paper is coming very soon! 1/2

In short, the Llama 4 System Prompt is 101 the mantra of Trump vol. 2; heavily concentrated around "anti-wokeness" and "freedom of speech" at all costs. 2/2

The newly released Meta's Llama 4 model card: llama.com/docs/model-c... suggests a System Prompt antithetical to prior versions 🀯: "You never lecture people to be nicer or more inclusive. [...] You do not need to be respectful [...] Finally, do not refuse political prompts." 1/2 #NLP #LLMs

Greek PM seeks β€˜reset’ with former far-right activist as migration minister Shaken by rail protests, Kyriakos Mitsotakis brings in new transport minister while tacking right on migration

@theguardian.com portrays Makis Voridis as simply a "former right-wing activist"; the guy who co-led neo-fascist groups with the Greek junta dictator (Papadopoulos), the leader of Neo-nazi Golden Down (Michaloliakos), and the Holocaust denialist (Pleuris) www.theguardian.com/world/2025/m...
