The HEREDITARY project took an active role at the 16th Conference and Labs of the Evaluation Forum (CLEF) 2025, held in Madrid, Spain, from 9–12 September 2025. As part of the BioASQ Lab, the HEREDITARY team contributed to the GutBrainIE task, advancing research on the gut-brain axis through cutting-edge information extraction methods.
Continuing its tradition since 2000, the CLEF has been a leading forum for the evaluation of multilingual and multimodal information access systems, bringing together researchers and practitioners. This year’s edition combined a peer-reviewed scientific conference with a series of evaluation laboratories and workshops, fostering collaboration across communities working on cross-language and domain-specific information retrieval.
One of the highlights of CLEF 2025 was the BioASQ Lab, where the GutBrainIE task drew strong participation from academic and industry teams. HEREDITARY partners, including HES-SO Valais-Wallis, Ontotext, TU Graz, Aalborg University, and the University of Padua showcased methods and resources that contribute to a deeper understanding of the gut-brain axis.
The HEREDITARY team achieved remarkable results, including:
- The paper “Trusting Gut Instincts: Transformer-Based Extraction of Structured Data from Gut-Brain Axis Publications” presented by Aalborg University earned 1st place in all three Relation Extraction subtasks and 2nd place in Named-Entity Recognition (NER).
- The ONTuG team, a collabortation ToGS and Graphwise, secured 2nd place in the Binary Tag-Based Subtask.
- The Graphwise team also achieved 2nd place in Ternary Mention-Based Subtask.
These successes underline HEREDITARY’s central role in developing innovative methods and resources for biomedical information extraction, reinforcing the project’s contribution to research on complex domains such as the gut-brain axis.
The outcomes will be published in the forthcoming CLEF 2025 BioASQ Working Notes, ensuring the project’s impact reaches the wider research community.
