Large Language Models for the Galician-Portuguese Diasystem
Pablo Gamallo
CiTIUS / Universidade de Santiago de Compostela
Abstract
I will do a systematic exploration of strategies for pretraining generative Large Language Models (LLMs) within the Galician-Portuguese diasystem. We investigate the impact of combining versus separating linguistic varieties during continued pretraining, the trade-offs between large-scale noisy data and smaller high-quality corpora, and the potential gains from incorporating instruction-based data during the training phase instead of in post-training (e.g., instruction tuning). In sum, I will try to give some hints on how to improve an LLM, taking into account factors such as the quality and size of the corpus, language varieties used and the ability to understand instructions.
Short Bio
Pablo Gamallo defended his Linguistics thesis in 1998 at the Université Blaise Pascal (France), and since 2004, he has been working at the University of Santiago de Compostela (Spain), first as a Ramón y Cajal research fellow and now as Full Professor. He was promoter and founding partner of Cilenis, spin-off of the University of Santiago de Compostela on language technologies. Concerning his research activities, he is a member of the Centro Singular de Investigación en Tecnoloxías Intelixentes (CiTIUS). His main scientific interest is Natural Language Processing and Information Extraction. At present, he is the Coordinator of the European project HYBRIDS, a MSC Doctoral Network with nine European Beneficiaries, and is one of the Principal Investigators of Proxecto NÓS, an ambitous project aimed at building linguistic resources (corpora, datasets, and language models) for Galician language.
An ontology for the Language Domain
Pedro Rangel Henriques
Algoritmi / Universidade do Minho
Abstract
After four decades in the study of (formal) languages, the time has come to pause, reflect on the insights gained, and weave an ontology that elegantly connects the myriad facets of this rich domain, laying the foundation for a deeper characterization. In this talk, I invite you to explore topics such as knowledge representations, language types and their subclasses, language affinities, blended language paradigms, problem-solving, programming, reasoning frameworks, computational thinking, grammars, quality, language processing, interpretation, compilation, and static analysis, among others. Through this journey, I will adopt a structured lens, presenting concise slices of the ontology. My aim is not to reach a singular destination but to meander thoughtfully through these interwoven themes, embracing the exploration itself as the reward.

Agentic AI: state of the art, challenges and limitations
Paulo Quaresma
VISTA Lab / Algoritmi / Universidade de Évora
Abstract
In this talk an overview of the current state of the art of agentic artificial intelligence systems will be presented. Recent advancements in the field, highlighting how these systems can be developed and applied to different domains, will be discussed. A special focus will be done on the current challenges and limitations associated with the development of trustworthy AI agentic systems, namely, systems with the following characteristics: explainability, transparency, privacy, security, accountability, fairness, inclusiveness, reliability, and ethics.
