SWoT group

A Web space for the Semantic Web of Things (SWoT) group's research work conducted at Intelligent Systems lab(i-Lab), Dept. of Cultural Technology and Comm., University of the Aegean.

About Us

Semantic Web of Things group, founded in 2020, conducts research on the following topics:

Ontology Eng., Semantic Web, IoT/WoT, Semantic Web of Things, Semantic Data Management, Semantic trajectories, Conversational AI and KGs , Linked Data.

A list of peer-reviewed papers authored by our group can be found at Google Scholar profile.
A list of ontologies developed (co-developed) can be found here and at GitHub!
A list of source code (ontologies and apps) can be found at GitHub!
A video of selected apps demo at YouTube can be found here!
