Martim Zanatti completed his master's degree in Computer Science and Engineering in September of 2021 at Instituto Superior Técnico. He holds a BSc in Computer Science and Engineering, completed in July 2019 at Instituto Superior Técnico and, since February 2022, he is pursuing a PhD in Computer Science and Engineering. His area of research is within the field of Natural Language Processing (NLP), where he is trying several NLP tasks for Portuguese Legal documents, such as automatic summarization, extreme multi-label classification, segmentation of judgments into sections and evaluation metrics for summarization. From September 2021 to September 2023, he worked on the IRIS project, a collaboration between INESC-ID and the Supreme Court of Justice, focused on producing automatic summaries of judgments and labeling each judgment with relevant descriptors. He is now involved in the Center for Responsible AI project. As of September 2024, he serves as a professor at the Faculdade de Direito, Universidade de Lisboa, in the AI & Law master’s program.

Institution / Organization
2025/06/05 - 2025/06/05 In June 2025, I presented a research poster at the Summer Demo Day 2025, showcasing preliminary work on the role of Large Language Models (LLMs) in the evaluation of legal summaries. The poster highlighted the limitations of traditional metrics like ROUGE in capturing semantic and legal adequacy, and proposed the use of LLMs for more nuanced, multi-dimensional evaluation tailored to the legal domain.
