Workshop on Ontology and Semantics of Explanations and Trustworthy AI

OSETAI 2026 is a workshop about the formal representation and characterization of explanations and trust. It is part of JOWO 2026 and is co-organized by the Horizon Europe project DigiPass CSA.

The proceedings will be published in the CEUR-WS series as part of the JOWO 2026 proceedings.

This is the first workshop organized under this name. The direct precursors to OSETAI are DAO-XAI (Data meets Applied Ontologies in Explainable AI), held in 2021 and 2024, and DCLXVI (Designing the Conceptual Landscape for a XAIR Validation Infrastructure), held in 2024. Precursor events to DAO-XAI had already been part of JOWO 2017 (DAO 2017 Workshop) and JOWO 2019 (DAO-SI 2019 Workshop).
