The 4th Workshop on Foundational Ontology (FOUST IV) was held in September 2020. It was part of JOWO 2020, FOIS 2020, and the Bolzano Summer of Knowledge 2020.
Foundational ontologies are essential for tackling interoperability problems of systems and software. However, the comparison of different foundational ontologies is itself an interoperability problem.
The FOUST workshop series aims at contributing to the theory and practice of foundational ontologies broadly understood, and specifically addresses systematic comparisons between foundational ontologies.
