Abstract In this chapter, we provide an overview of the current trends in using
semantic technologies in the IoT domain, presenting practical applications and use
cases in different domains, such as in the healthcare domain (home care and occupational health), disaster management, public events, precision agriculture, intelligent transportation, building and infrastructure management. More specifically, we
elaborate on semantic web-enabled middleware, frameworks and architectures (e.g.
semantic descriptors for M2M) proposed to overcome the limitations of device and
data heterogeneity. We present recent advances in structuring, modelling (e.g. RDFa,
JSON-LD) and semantically enriching data and information derived from sensor
environments, focusing on the advanced conceptual modelling capabilities offered
by semantic web ontology languages (e.g. RDF/OWL2). Querying and validation
solutions on top of RDF graphs and Linked Data (e.g. SPARQL, SPIN and SHACL)
are also presented. Furthermore, insights are provided on reasoning, aggregation,
fusion and interpretation solutions that aim to intelligently process and ingest sensor
information, infusing also human awareness for advanced situational awareness.
