Practical Approach and Applications to the 4th Industrial Revolution [Keynote]

Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. In the era of the Fourth Industrial Revolution, there is a lot of confusion caused by the lack of understanding of its nature. Understanding the nature of the Fourth Industrial Revolution requires a systen1atic and insightful view of goal, strategy, and tactics(technologies such as IoT, big data, 5G, AI, and digital twin). This approach will eventually enable to realize the need of technology convergence and further successful step to various applications such as sn1art city and sn1art factory. We have atten1pted a practical approach to the Fourth Industrial Revolution through Hyper-connected Data Ecosysten1 project since 2017. We encountered n1any issues in the phases of conceptual design, n1odelling, and implen1entation, but finally resolved then1 and gained lessons learned as a practical use case. In this talk, I'll give son1e hints to n1ove toward a better future by also showing various big data analysis and visualization results.
