IWSIoT 2025: 4th International Workshop on Semantic IoT HTWK, Leipzig, Germany, November 26-28, 2025

Introduction

The Semantic Internet of Things (SIoT) refers to the integration of semantic technologies into the Internet of Things (IoT) ecosystem. Unlike conventional IoT, which primarily emphasizes device connectivity and data exchange, SIoT introduces meaning, structure, and contextual understanding to the data generated by IoT devices. Semantic technologies—such as ontologies, linked data, and knowledge graphs—enable systems to not only exchange data but also interpret, reason, and derive knowledge from it.

By embedding semantics, SIoT enhances interoperability across heterogeneous devices, facilitates context-aware decision-making, and improves the usability of IoT-based services and applications. It acts as a bridge between the physical environment of sensors, devices, and actuators and the digital domain of semantic reasoning and knowledge representation, thereby transforming raw IoT data into actionable intelligence.

The field of SIoT is rapidly evolving, particularly with its convergence with artificial intelligence (AI), machine learning (ML), and big data analytics. This synergy empowers IoT systems to become more adaptive, autonomous, and intelligent, opening new possibilities in domains such as smart cities, healthcare, transportation, and industrial automation.

Objective

The primary objective of SIoT is to augment the IoT ecosystem with semantic intelligence in order to:

1. Enhance interoperability – Enable seamless communication between heterogeneous devices, systems, and services across diverse domains.
2. Facilitate context-aware reasoning – Support systems in interpreting data meaningfully to improve automation, personalization, and decision-making.
3. Transform data into knowledge – Convert raw sensor outputs into structured, machine-interpretable information that can be reasoned over.
4. Support intelligent applications – Leverage the integration of semantics with AI and ML to create adaptive, predictive, and self-organizing IoT environments.
5. Promote cross-domain scalability – Enable IoT solutions to function across industries, ensuring broader adoption and innovation.

By achieving these objectives, SIoT aims to create smarter, more interconnected ecosystems where devices and services do not merely coexist but actively collaborate to deliver intelligent, human-centric outcomes.
