토픽모델링을 이용한 자율주행 연구 동향 분석

Abstract

With the recent development of the fourth industry, there is a lot of interest in research related to artificial intelligence, the Internet of Things, and big data, and various convergence studies are being conducted on one technology. Among them, autonomous driving research is increasing exponentially, and countries around the world are investing not only in research support but also in autonomous driving by changing legal regulations. This study examines annual research topic trends in LDA and TF-IDF from papers related to autonomous driving and vehicles in the Scopus journal and extracted promising topics in 2023 using Week Signal process. In LDA, it is not limited to 'vehicle' in autonomous vehicle analysis, but has been studied in various ways such as aviation and underwater, and various research algorithms have been extracted without focusing on 'vehicle' in autonomous driving analysis. In TF-IDF, we can find out the new topics that appeared in the latest year, through the Week Signal. It is possible to guess that research such as artificial intelligence research and environmental factors would be promising, as well as research on stability and accuracy regarding safety.
