The Semantic Web: ESWC 2025 Satellite Events

This book constitutes the proceedings of the satellite events held at the XXX Semantic Web Conference, ESWC 2025, held in Portoroz, Slovenia, during June 12, 2025.

The 31 Posters & Demos papers are presented together with 12 PhD Symposium papers and 7 Industry papers in this book were carefully reviewed and selected from 43 Posters& Demo papers, 15 PHD Symsposium papers and 14 Industry papers.

The theme of the conference was Empowering Knowledge through Semantics: From Knowledge Graphs to Neurosemantics. The satellite events are an important aspect of facilitating the main conference discussion as well as fundamental questions about how we acquire, represent, use, and interact with knowledge and semantics.

The satellite events of ESWC 2025 include the poster and demo session, the PhD symposium, the industry track, project networking, and workshops and tutorials.
