Today we will be presenting our work "PartisanLens: A Multilingual Dataset of Hyperpartisan and Conspiratorial Immigration Narratives in European Media". 📍 Poster Board #41 🕓 16:30–18:00 📌 Poster Hall 🤝 If you're around, come say hi! #EACL2026 #NLP

Una reflexión personal: ¿y si la IA pudiera detectar a tiempo señales de malestar emocional en lo que escribimos? 👇 🔗theconversation.com/cuando-la-ia-e…

Paper accepted at #LREC2026 🎉 Mute Cods: A Multilingual Telegram Dataset with Benchmark Models for Conspiracy Theory Detection 🌐 w/ Katarina Laken, Erik Marino, Davide Bassi, Søren Fomsgaard, Michele Maggini, Renata Vieira, Marcos Garcia & Sara Tonelli See you in Palma! ☀️📚

🥳 @itspalomap paper "Can LLMs Evaluate What They Cannot Annotate? Revisiting LLM Reliability in Hate Speech Detection" has been accepted at #LREC2026 w/ @davidoterof & @patrimrodilla See you in Palma 🇪🇸✈️ 🔗arxiv.org/abs/2512.09662 📀github.com/palomapiot/hat…

Hoy, en el #SaferInternetDay, reafirmamos nuestro compromiso: investigamos para detectar y frenar mensajes de odio y conductas abusivas, y para identificar señales de riesgo en redes sociales, con rigor y responsabilidad. Por un internet más seguro.

🎉 Our paper “PartisanLens: A Multilingual Dataset of Hyperpartisan and Conspiratorial Immigration Narratives in European Media” accepted at #EACL2026 🇲🇦 main conference. Work done with Michele Maggini @itspalomap @anxopvila and the @HYBRIDS_MSCA team! See you in Rabat! ✈️📍

Happy to see this work with @davidoterof accepted at #ECIR2026. A deceptively simple yet effective idea: improve PRF through selective relevance feedback using small LLMs, denoising the feedback set without polluting or overcomplicating the underlying PRF model.

Encantada de participar na xornada “Onde queda a ética cando falamos de IA?” que tivo lugar o pasado luns 1 de decembro no CIE Mans. Foi un pracer compartir reflexións e aprendizaxes nun ambiente tan enriquecedor ✨ 📸 Fotos: ESTUDIOS MANS

O luns 1 de decembro no CIE Mans terá lugar a xornada “Onde queda a ética cando falamos de IA?”. @itspalomap achegará unha visión investigadora sobre o impacto positivo e negativo da IA na sociedade. Máis info e inscricións 👉 manspaideia.com/xornada-inteli…

🎓 Happy to share our latest work: “Beyond questions: Leveraging ColBERT for keyphrase search”. A study on improving dense retrieval for keyphrase-style queries using ColBERTKP. 🔗sciencedirect.com/science/articl… With @jparapar & @craig_macdonald

This week @wangxieric & @eliseobao presented our works at CIKM 2025. We unveiled: TalkDep: Clinically Grounded LLM Personas for Conversation-Centric Depression Screening and ReDSM5: A Reddit Dataset for DSM-5 Depression Detection. Great work! #CIKM2025 w/ @anxopvila

Just published @itspalomap's agentic software for supporting hate speech moderation, WATCHED is a Web Agent that combines LLMs, BERT-based classification, and explainable reasoning to assist moderators in identifying and understanding harmful content. 🔗 authors.elsevier.com/sd/article/S23…

The Special Issue on LLMs as Evaluators in Springer Nature is now open for submissions. We welcome contributions on reliability and bias, human–LLM collaboration, efficiency, and applications across domains such as IR, NLP, healthcare, or social computing. link.springer.com/collections/cj…

🧠💬 How does depression "talk" on social media? @eliseobao’s work explores depression-related language on Reddit & Twitter using relevance-based models to better understand and detect mental health risks. 🔗sciencedirect.com/science/articl… w/ @anxopvila & @davidoterof

🎉 Very proud of @JorgeGabin_! Today, he successfully defended his PhD Thesis titled 'Improving the Search Experience on Complex Search Scenarios' 📚 Big thanks to @wangxieric, @patrimrodilla and @DavidELosada, for serving on the committee
