Overview of the 2024 ALTA Shared Task: Normalise Adverse Drug Events

Diego Mollá, Xiang Dai, Sarvnaz Karimi, Cécile Paris


Abstract
The ALTA shared tasks have been running annually since 2010. In 2025, the task focuses on the normalisation of Adverse Drug Events (ADE) found in forum posts to their corresponding standard term specified by the Medical Dictionary for Regulatory Activities (MedDRA). This is a comprehensive ontology of ADEs, which contains more ADE descriptions than those mentioned in the available training dataset. This makes the task more challenging than a straightforward supervised classification. We present the task, the evaluation criteria, and the results of the systems participating in the shared task.
