Rapid growth in the Internet of Things (IoT) means that connected sensors and actuators will be inundating the Web infrastructure with data. Semantics is increasingly seen as a key enabler for integration of sensor data and the broader Web ecosystem. The W3C and the Open Geospatial Consortium standardisation bodies have taken a second look at the Semantic Sensor Network ontology and have published a new standard ontology for representing Sensors, Observations, Sampling, Actuation and Sensor Networks. Analytical and reasoning capabilities afforded by Semantic Web standards and technologies are considered important for developing advanced applications that go from capturing observations to recognition of events, deeper insights and actions. Furthermore, the contribution of semantics to sensing and actuation patterns is currently being explored. Major industries including manufacturing, transport and logistics, personal and public health, smart cities and smart energy, crisis management and many others are spanning commercial, civic, and scientific operations that involve sensors, web, services and semantics. This workshop will continue the activity started within ISWC in 2006, and complemented by special tracks at ESWC since 2010. This 2018 edition benefits from renewed energy arising from the October 2017 W3C recommendation and OGC standard and, more importantly, increases significance due to the growth of IoT-enabled applications.

The proceedings of the Workshop are online at: http://ceur-ws.org/Vol-2213/

The SSN workshop is a full day event that revives and strengthens the community around the ontological representation of sensor and actuation data and welcomes researchers from related communities. It is highly interactive, so as to facilitate discussions among participants that could result in future collaborative work. Two invited talks will be given by Armin Haller and Michael Koster, and authors will present research papers in either long or short format, together with a demonstration. Demonstrations have been a successful feature of SSN in the past. Sufficient time will be dedicated to questions and answers for each paper. The session will end with a general discussion on experience with relevant ontologies and ideas for next steps.

Maxime Lefrançois

MINES Saint-Étienne, France

Maxime Lefrançois is a former student of the Ecole Normale Supérieure de Cachan, and prepared and passed the Agrégation exam in Mechanics in 2008. He then received a Master degree from Grenoble INP in Signal Processing in 2009, and another from Université Grenoble 2 in Informatics in 2010, while being sessional Lecturer in Mechanics at Université Grenoble 1. During his Ph.D. he prepared in the WIMMICS team, INRIA Sophia-Antipolis, he worked on knowledge representation and reasoning for the Meaning-Text linguistic theory. Between 2014 and 2017, he was a post-doctoral researcher at the École des Mines de Saint-Étienne, and was involved in several bilateral, national, and European projects, including the ITEA2 SEAS project in the context of which he bootstrapped the development of the SEAS ontology: a modular and versioned ontology built on top of the OGC&W3C SOSA/SSN standard, that consists of simple ontology patterns that can be instantiated for different engineering-related verticals. Maxime is one of the co-editors of the SOSA/SSN standard, and currently leads an ETSI Specialist Task Force (STF 556) to inject the SEAS proposals in the ETSI SmartM2M SAREF European standard ontology. He also initiated the development of the SPARQL-Generate RDF lifting language, and the cdt:ucum Datatypes. Finally, he has experience in organizing workshops and tutorials in international events. Since 2017 he is Associate Professor in the Connected-Intelligence team at the École des Mines de Saint-Étienne, France.
