Semantic modeling and design patterns for IoT ecosystems

In recent years, there has been an increasing diffusion of IoT-based devices that collect and share sensor data for a wide variety of applications. These data are highly heterogeneous as they are obtained from various data sources utilizing different representation schemes, which represents a great richness in terms of stored information but also a strong limitation in terms of interoperability. Since traditional software modeling is not able to cope with this issue, several semantic approaches based on ontologies and/or linked data have been proposed in recent literature. Semantic modeling provides a potential basis for interoperating among different systems and applications in the IoT. The semantic interoperability can be implemented for just one specific IoT device or for entire IoT ecosystems in which different IoT devices interact with each other. The goal of this Special Issue is to provide insights on recent advances in semantic modeling for IoT by presenting original scientific contributions in the form of theoretical foundations, models, experimental research, and case studies.
