토픽 모델링을 활용한 국내 자동차 특허기반 기술개발 동향 분석

초록

In addition to the semiconductor, shipbuilding, and heavy and chemical industries, Korea's automobile industry occupies an important position in the economic ecosystem such as job creation and tax revenue. In particular, since the automobile industry has a high connection with SMEs that manufacture more than 20,000 parts, it is necessary to look at technology trends and trends of change. The purpose of this study is to examine the flow and change from a technical perspective and assess the future of the automobile industry, which is facing a major transformation period such as autonomous driving, electricity, and transition to the service industry with the advent of the 4th industrial revolution. In order to examine technology trends, topic modeling was used as a research method in this study, and importance analysis between key words was performed through network analysis. For this study, 30,088 technology patents registered from the 1990s to the present were classified into inventors, research date, and invention content summary, and then an in-depth analysis was conducted through topic modeling. Precedent research using topic modeling is limited to daily and comprehensive frequency analysis and emotional analysis of SNS, papers, and portal comments, but this study has academic significance and differences in that it can examine the current state of technological development in the automobile industry and provide insights on future technological implications by deriving representative keywords for each field and the development of technology patents every 10 years.
