The objective of this book is to present a comprehensive evaluation of the smart revolution, including its social and economic impacts. It proposes a modern framework to help assess how recent information and communication technologies (ICTs) can contribute to societies as a whole. The authors offer a guide to how advanced network technologies have led to a greater variety of applications and social networking services. These allow people to connect with each other both at a more personal and global level, and will ultimately herald a new era of ICTs that will shape the "digital society."
