Big data, IoT and semantics

Big data and the Internet of things are two parallel universes, but they are so close that in most cases they blend together. The amount of devices that connect to the internet grows day by day and they bring millions of data. The IoT generates unprecedented amounts of data and this impacts on the entire big data universe. The IoT and big data are clearly growing apace, and are set to transform many areas of business and everyday life. Semantic technologies play a fundamental role in reducing incompatibilities among data formats and providing an additional layer on which applications can be built, to reason over data and extract new meaningful information. In this chapter we report the most common approaches adopted in dealing with Big Data and IoT problems and explore some of the semantic based solutions which address such problematics.
