Comparison of Smart City Development in Japan and China by Text Mining Analysis

With the information technology development, Smart city has become popular worldwide in recent years. However, the applications of smart cities are diversified among countries to achieve different objectives. This research compared how the smart city concept has been applied differently in China and Japan, two major economies in East Asia, through text mining techniques on relevant journal articles. The journal articles in either countries are analyzed by software, KH-Coder, which automatically extracts word, count the frequency of each word then using statistic method to classify and find the relationship among each high-frequency word. The results imply that in the case of Japan, energy efficiency in local level is a primary focus while the smart city concept is applied as a basic infrastructure for economic development in China.
