Abstract

To analyze the main topics related to the use of blockchain technology, the Topic Modeling Technique was applied to the 'Blockchain Technology Utilization' big data shown in newspaper articles. To this end, from 2013 to 2019, when newspaper articles on the use of blockchain technology first appeared, the topics were extracted from 21 newspapers and analyzed by time to 15,537 articles. As a result of the analysis, articles related to the utilization of blockchain technology have increased exponentially since 2015 and focused on IT_science and economics. Key words related to cryptocurrency, bitcoin and virtual currency were weighted high, although they differed depending on time. Blockchain technology, which had focused on financial transactions, gradually expanded to big data, Internet of Things and artificial intelligence. As a result, changes in corporate topics were also made together to expand into various fields at banks for financial transactions, focusing on large and global companies. The study showed how these topics were changing, along with the main topics in newspaper articles related to the use of blockchain technology.

이 연구에서는 블록체인 기술의 활용과 관련된 주요 토픽을 분석하기 위해 신문기사에 나타난 '블록체인 기술 활용' 빅데이터를 토픽 모델링기법을 적용하였다. 이를 위해 2013년부터 2019년까지, 21개의 신문사로부터 15,617건을 대상으로 토픽을 추출하고 주요 트렌트를 시기별로 구분하여 분석하였다. 분석결과 블록체인기술 활용과 관련된 기사는 2015년부터 기하급수적으로 증가하였으며 IT_과학 분야와 경제 분야에 집중되었다. 기간에 따라 차이는 있지만 암호화폐, 비트코인, 가상화폐와 관련된 키워드의 가중치가 높았다. 금융거래에 집중되었던 블록체인기술은 빅데이터, 사물인터넷, 인공지능으로 점차 확대되었다. 이에 따라 기업의 토픽 변화도 함께 이루어져 금융거래를 위한 은행에서 다양한 분야로 확대되면서 대기업과 글로벌기업으로 집중되었다. 이 연구를 통해 블록체인기술의 활용과 관련한 신문기사의 주요 토픽과 함께 이러한 토픽들이 어떠한 변화추이를 보이고 있는지에 대해 확인할 수 있었다.
