🥳 @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…

LLM-Assisted Pseudo-Relevance Feedback @davidoterof et al. propose using LLMs to filter pseudo-relevant documents before RM3 query expansion, reducing topic drift while avoiding hallucinations. 📝 arxiv.org/abs/2601.11238 👨🏽‍💻 github.com/davidoterof/ec…

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.

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

Couldn’t be prouder! 🎉 @anxopvila has received @sepln’s Best NLP PhD Thesis Award, a huge honor and well-deserved recognition of his work. 👏🌟

Now at #CLEF2025 @UNED! 🚀 @anxopvila is presenting this year’s @earlyrisk Lab overview. Join us at the #eRisk sessions today and tomorrow to discover the great work of our participating teams!

Para estos días y estos tiempos que corren sin freno, esto de Marías.

Had a great time during the poster session today! Many interesting conversations and cool ideas 🚀 #SIGIR2025

If you care about multiple comparisons in IR (you should!), you might want to check our work on this problem. Spoiler: Bonferroni is ok, but there are better alternatives. #SIGIR2025 arxiv.org/abs/2501.03930

Desde el @IRLab_UDC queremos agradecer a Enrique Carballo de @laopinioncoruna por el gran trabajo de difusión y síntesis de nuestros resultados de investigación: laopinioncoruna.es/coruna/2025/05… ¡Gracias por dar visibilidad a la ciencia, esto nos motiva a seguir buscando soluciones!

Just now, @itspalomap presented our paper: Decoding Hate: Exploring Language Models' Reactions to Hate Speech at #NAACL2025! 🧠💬 How do LLMs react to toxic content? Proud of her work! #NLP #LLM #HateSpeechDetection 📄 Paper: aclanthology.org/2025.naacl-lon…

Last day of #ECIR2025 listening to very interesting talks of some friends! @anxopvila @itspalomap @sciueferrara

Today @eliseobao presented MindWell: A Conversational Agent for Professional Depression Screening on Social Media at the #ECIR2025 demo session in Lucca 🇮🇹! Mindwell is a system designed with the help of health professionals to screen users at risk from social media content!

The @IRLab_UDC finishes its participation at #ECIR2025 with @eliseobao demoing a conversational agent for depression screening, @anxopvila presenting the eRisk 2025 challenges, and @itspalomap sharing her work on distilling efficient & explainable hate speech detectors
