Major industries including manufacturing, transport and logistics, personal and public health, smart cities and smart energy, crisis management and many others spanning commercial, civic, and scientific operations that involve sensors and actuators exposed on the web. In potential combination with other AI techniques, the Semantic Web offers representational, analytical, and reasoning capabilities that are important for the development of advanced applications that rely on sensors and actuators, potentially geographically distributed and/or exposed on the Web of Things. SAW 2019 targets Semantic Web practitioners that represent, reason with, publish, or use knowledge related to sensors and actuators in general. This workshop gives a breath of fresh air to the Semantic Sensor Network Workshop series that started within ISWC in 2006, was complemented by special tracks at ESWC since 2010, and was resumed by a successful 9th edition at ISWC 2019 which benefited from renewed energy arising from the October 2017 W3C recommendation and OGC standard, and more importantly, increases significance due to the growth in IoT enabled applications. SAW 2019 is organized by the contributors to SOSA/SSN and particularly welcomes early adopters of this ontology, whose work may not be mature enough to get published at the main conference, or consist in migrating previous work.

The SAW workshop is a half-day event that 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 were given by Raphaël Troncy and Payam Barnaghi, and three long research papers. The event ended with a general discussion on experience with relevant ontologies and ideas for next steps.

Raphaël Troncy


Keynote: Semantic Technologies for Connected Vehicles in a Web of Things Environment (slides)

Abstract: Vehicles are evolving from purely mechanical entities to highly connected and autonomous ones. This transition is made possible thanks to the emergence of recent technologies, among others 5G, big data or deep learning. While this leads to new business and technical opportunities, making vehicle fleets interoperable is still highly challenging. Many standards are competing and no unique solution fits all situations. Application developers in the automotive domain have to deal with thousands of different signals and attributes, represented in highly heterogeneous formats, and coming from various car architectures. This situation limits the development of modern applications. We hypothesize that a formal model of car signals, in which the definition of signals are uncorrelated with the physical implementations producing them, as well as a common data layer, would improve interoperability between connected cars and their ecosystem. We also propose to develop tools to automatically produce new information from vehicle data and formally enrich contextual knowledge about drivers, vehicles and their situations. In this talk, we present VSSo, a vehicle signal and attribute ontology that builds on the automotive standard VSS, and that follows the SSN/SOSA design pattern for representing observations and actuations. VSSo is comprehensive while being extensible for OEMs, so that they can use additional private signals in an interoperable way. VSSo is used as a future data model in the W3C automotive Working Group. We contribute to the Web of Things specification by aligning VSSo and the driving context ontology with it. We provide automotive-specific requirements and implementations, and highlight the benefit of the Web of Things for automotive application developers.

Payam Barnaghi

University of Surrey, UK

Keynote: Search, Discovery and Analysis of Sensory Data Streams (slides)

Abstract: This talk will discuss the query, search and discovery issues in finding and accessing sensory data streams their content on the Web. Semantic technologies have been widely investigated and used to publish linked and interoperable sensor data on the Web. The semantically annotated data is seen as a key enabler to create a large-scale and integrated web of sensors, actuators and their data. However, discovering, integrating and analysis of patterns and content of the sensor data streams play even a more important role in creating real-world applications using the connected sensing technologies. Using AI, machine learning and analytical models can lead to extracting actionable-information from raw sensory data and integrating heterogeneous and multimodal data sources. We will discuss the applications of AI and machine learning in processing sensor data streams and will explore real-world use-cases in healthcare and remote monitoring applications.

Bio: Payam Barnaghi is Professor of Machine Intelligence in the Centre for Vision, Speech and Signal Processing (CVSSP) at the University of Surrey. He works on the development of new machine learning and semantic computing algorithms and techniques for future internet and web systems, with a focus on Internet of Things, time-series data analysis, information search and retrieval and their applications in healthcare and smart cities. He is Deputy Director of the Care Research and Technology Centre at the UK Dementia Research Institute (UK DRI).


The SAW workshop will be a full day event meant to be highly interactive, so as to facilitate discussions among participants that could result in future collaborative work. A keynote/invited talk will be planned, and followed by authors presenting their paper. We will ensure sufficient time will be dedicated to questions and answers for each paper. The session will end with a general discussion session to discuss experience with the ontologies and decide on the next steps. It is expected that most of the standard's editors will be present.
