This study aims to examine the trend in changes in keywords and topics of the 4th Industrial Revolution as it pertains to education between 2018 and 2020, and to derive future development directions and educational implications. For the public sector, posts on the Ministry of Education s website and its monthly magazine have been targeted. For the private sector, articles from eleven comprehensive daily newspapers nationwide are targeted. After collecting data through web crawling, keyword analysis, topic modeling, and sentiment analysis were performed using R. As a result, technical education, middle and high school education, and university education were found to be emphasized in the Ministry of Education s documents. Technical education showed an extension to career and vocational education. In the case of middle and high school education, the emphasis was on student-specific education and on the strategic location of high schools. In university education, cooperation through subjects such as universities, companies, and society were emphasized. On the other hand, in daily newspapers, interest in AI was steadily high. In middle and high school education, major changes in the subjects on the College Scholastic Ability Test were dealt with, and career education and government policies, and political circles were dealt with broadly. Finally, the proportion of positive words in the public sector increased, while the proportion of negative words in private sector increased.
