This tutorial was prepared by the Semantic Interoperability Expert Group of the AIOTI WG Standardization. It was presented by Martin Bauer, Raúl García-Castro, Amélie Gyrard, María Poveda Villalón and Dave Raggett at theIoT Week 2021 on 2 September.
The tutorial introduces the idea of semantic interoperability and the use of ontologies. Participants learn what ontology is and how it can be used. A focus is on reusing and extending existing ontologies, e.g. SAREF, and getting experience in finding the right ontologies for a given purpose in an ontology catalogue. The semantic modelling of two use cases is shown, starting from the smart home domain, which is extended to smart health. The tutorial concludes with some semantic web best practices for better ontology reuse.
