Two contributions to the international reference forum reinforce CiTIUS' leadership in information search and verification systems
The prestigious ACM SIGIR 2025 conference, considered the world's leading forum in information retrieval and recommendation systems, selects and hosts the presentation of two works from the center.
The 48th edition of the international SIGIR conference, recently held in Padua (Italy), hosted the presentation of two new contributions from CiTIUS to the field of information retrieval, a key area for artificial intelligence systems focused on efficiently organizing, filtering, and accessing knowledge. Over five days, the world's leading experts gathered at this event, organized by the ACM (Association for Computing Machinery) and considered the most prestigious international forum in the area.
After a rigorous review process, the CiTIUS team shared two new scientific approaches at this reference meeting, which annually brings together the most outstanding research community in the field. The first, developed by Xiana Carrera, Marcos Fernández Pichel, and David E. Losada, investigates how Large Language Models (or LLMs) could be used to generate more precise medical queries to improve the reliability and safety of results obtained by search systems in health contexts. This work was presented in the "LLMs for IR" session, in the Short Papers block, reflecting one of the congress's most active lines. The second contribution, in collaboration with the University of Regensburg (Germany) and signed by Marcos Fernández Pichel and David E. Losada, focuses on techniques to guide users in information verification tasks, helping them locate web documents that can cross-check claims present in original news.
Both contributions have been entirely developed at CiTIUS (a center co-financed by the European Union through the Galicia Feder 2021‑2027 Program), consolidating its position as an international reference in research applied to search, retrieval, and critical verification of information. Two new steps in the line of research excellence of the center, which has showcased its latest advances to an audience of utmost relevance, as validated by the conference classification system of the Computing Research and Education Association of Australasia (CORE), one of the most established references in the field of computer science. According to this classification, the SIGIR conference consistently maintains its position in the highest category (A*), reserved for events with exceptional impact, a high level of scrutiny in the review of works, and sustained influence on the scientific evolution of the area.
Participation in this forum has also allowed strengthening collaboration networks, giving visibility to high-impact social research, and aligning the center with the most relevant technological challenges of the digital society.
