An International Comparative Study of Internet of Things Technologies Using Keywords Extracted from Newspapers

抄録

Currently, a large amount of news and articles related to Internet of Things (IoT) are circulatingworldwide along with information about Industry 4.0-related technical developments. In 2011, the German government even adopted “Industrie 4.0/industry 4.0” as their national strategy to improve their global competitiveness. This study compares data from four countries: United States, Germany, China, and Japan. I perform clustering by the weight of group after extracting IoT-related keywords that have appeared in newspapers. It was seen that the United States focuses on the Internet/data processing technologies, and Germany focuses on the production/M2M (Machine to Machine) technologies. However, Japan and China lacked such focus.
