Overview of MentalRiskES at IberLEF 2025: Early Detection of Addiction Risk in Spanish

Resumen

This paper presents the MentalRiskES shared task organized at IberLEF 2025, as part of the 41st International Conference of the Spanish Society for Natural Language Processing. This task aims to promote the early detection of mental risk disorders in Spanish. We propose two detection tasks: Task 1 for risk detection of gambling disorders, Task 2 for risk detection of gambling disorders but determining the type of addiction. Furthermore, we asked participants to submit measurements of carbon emissions for their systems, emphasizing the need for sustainable natural language processing practices. In this third edition, 27 teams registered, 13 submitted results, and 12 presented papers. Most teams experimented with Transformers, including features, data augmentation, and preprocessing techniques.
