The market of the Internet of Things (IoT) is growing rapidly, and people will obtain even more benefits from the services that handle the composed IoT devices through cloud services in the future. The World Wide Web Consortium pursues dealing with IoT devices on Web layers, called the Web of things (WoT). Applications can access the functions of things anytime, anywhere by exposing things through...
Achieving the interoperability of Internet of Things (IoT) platforms raises a key challenge, as most current IoT applications are vertically integrated within separate silos without horizontal communications. In response to this, we propose the Semantics Extractor, a framework for automatic extraction of semantic graphs from REST interfaces exposed by IoT platforms. Through an iterative process of...
The vision of the Internet of Things (IoT) promises the capability of connecting billions of devices, resources and things together. In the realisation of this vision, we are currently neglecting the interoperability between devices that is caused by a heterogeneous landscape of things and which leads to the proliferation of isolated islands of custom IoT solutions. A first step towards enabling some...
Transparency and data integrity are crucial to any scientific study wanting to garner impact and credibility in the scientific community. The purpose of this paper is to discuss how this can be achieved using what we define as the Semantic Catalog. The catalog exploits community vocabularies as well as linked open data best practices to seamlessly describe and link things, data, and off-the-shelf...
Sensors are embedded nowadays in a growing number of everyday life objects. Smartphones, wearables, and sensor networks together play an important role in bridging the gap between physical and cyber worlds, a fundamental aspect of the Internet of Things vision. The ability to reuse sensor data integrated from multiple heterogeneous sources is a step towards building innovative applications and services...
In recent years, common-use devices' equipment has seen a leap transition in terms of shipped technology, introducing the so called “smart things” to the consumer market. To take full advantage of opportunities arising from connectivity, smart things approached the application realm bringing the novel Web of Things vision to life. In this paper, we propose an approach for modeling and implementing...
The technological advances in hardware and software communication technologies are speeding up the path towards the actualization of the Internet of Things. Nonetheless, novel requirements are emerging for the effective and efficient usage of the huge amount of available sensor information and functional capabilities. Several approaches have been proposed for leveraging the Web to this purpose (i...
