Semantic Interoperability has been identified as a crucial topic for the Internet of Things
enabling the so-called world of everything connected. A connected world of “Things” not only
requires development of infrastructure and new protocols but also deployment of new data
services capable of supporting multiple, scalable (cloud-based) and interoperable (crosssystems
and cross-domain) applications. Semantics plays a relevant role in this interoperability
requirement and thus the intersection between semantic web and the IoT is yet an unexplored
area that requires research attention and industry development.

The Connected World & Semantic Interoperability 2017 (CWSI) workshop is addressed to
developers, scientific researchers, industry experts and general audience interested in the
evolution of the Internet of connected things world. CWSI aims to provide the possibility to
explore interoperability research challenges and provide a room to expose research/scientific
ideas and industry vision/progress. CWSI is also a venue to explore new trends and
opportunities of using semantic web technologies for solving problems and creating new
solutions on emerging specialized paradigms like the current Internet of connected Things
using semantics towards the Internet of Everything Connected (IoE).

In the race of designing the connected world as part of the Internet of Things architecture,
academia and Information and Communication Technology (ICT) industry communities have
realized that a common problem to be tackled is the interoperability of the data and the
availability for providing cross-domain information services. Worldwide there is an increasingly
focusing on how to evolve communications technologies to enable a Connected World of
“Things”, thus CWSI 2017 workshop focuses on defining and architecting semantic-enabled
connected world of things systems and the ways to interact and be interconnected for offering
the always-promoted everything-connected interoperability paradigm.
