In November 2025, The European Centre for Algorithmic Transparency (ECAT) hosted a research workshop in Seville, Spain. The purpose of the event was to bring together researchers from across Europe to share insights on systemic risks of online platforms, particularly of very large online platforms and search engines (VLOPs and VLOSEs), as set out in the Digital Services Act (DSA).
For this edition of the Workshop, the specific focus was on potential risks to the mental and physical health of children and young people, and how these can be mitigated.
Preceding the workshop, ECAT ran a call for contributions, and of the 52 submissions, 14 were selected to join to share their insights in poster sessions or presentations. In addition, the programme consisted of three panel discussions, a keynote, a presentation by local students and an overview of relevant ECAT activities.
The main purpose of this Book of Abstracts is to share some of the many insights that were shared throughout the workshop. In the first section, summaries of the workshop sessions are presented. In the second section, the selected abstracts for the event’s poster sessions are reproduced.
