In recent years, the Internet of Things (IoT) and the Semantics and Web of Things (SWoT) have been more and more often combined to collect sensing data conforming to the semantic web stack, expose kg-based services and build smart applications. At the same time, the need for decentralized infrastructure to capture and transform data on the edge has gained attraction due to the real necessity to reduce the global carbon emission of centralized architectures. A step towards the so-called Green Web. For this edition of SWoCoT2023, there were 8 papers submitted for peer-review to this workshop. Out of these, 6 papers were accepted for this volume, 5 as regular papers and 1 as short paper.
