Study on the Trends of U-City and Smart City Researches using Text Mining Technology

Abstract

City is currently developing into intelligent city which adopts the ICT technology to resolve the problems and increase the competitiveness. This intelligent city is promoted under the name of U-City or Smart City, yet it is also criticized in the trend for what the differences between U-City and Smart City are. In this study, we draws the differences between U-City and Smart City from our distinctive research method, text mining which analyzes the trend of research papers, and contribute to direction of U-City study in the future. Through this analysis, the study results in that U-City focuses practical implementation in domestic cities while Smart City focuses technological development and provision of single service. However, this paper has a limitation as the subjective opinion was reflected to configure the sets of keywords, and only keywords and abstracts were analyzed. Therefore, further studies are needed to confirm the differences between U-City and Smart City with related research papers and reports.

“…어떤 분야에서 특정 키워드가 출현하는 논문이 많거나 특정한 연관관계의 키워드 들이 출현하는 논문이 많다는 것은 해당 분야의 연구동향을 설명하기에 적합한 특성이기 때문이다. 클수록 연관성이 크다고 판단한다(Lim et al, 2014). 연관 관계도에서 노드가 클수록 키워드의 출현비율이 높으며 선이 굵을수록 연관관계의 향상도 값이 높음을 의미한다.…”
