Abstract

The purpose of this study is to explore the trend of blockchain technology through analysis of patents and news articles using text mining, and to suggest the blockchain policy agenda by grasping social interests. For this purpose, 327 blockchain-related patent abstracts in Korea and 5,941 full-text online news articles were collected and preprocessed. 12 patent topics and 19 news topics were extracted with latent dirichlet allocation topic modeling. Analysis of patents showed that topics related to authentication and transaction accounted were largely predominant. Analysis of news articles showed that social interests are mainly concerned with cryptocurrency. Policy agendas were then derived for blockchain development. This study demonstrates the efficient and objective use of an automated technique for the analysis of large text documents. Additionally, specific policy agendas are proposed in this study which can inform future policy-making processes.

본 연구의 목적은 텍스트 마이닝을 활용하여 특허와 뉴스 기사 분석을 통해 블록체인 기술 동향을 탐색하고 사회적 관심을 파악하여 블록체인 정책의제를 제안하는 것이다. 이를 위해 국내 블록체인 특허 요약문 327건과 온라인 뉴스기사 전문 5,941건을 수집하고 전처리 과정을 거쳐 LDA 토픽모델링 방법을 사용하여 특허 토픽 12개와 뉴스 토픽 19개를 추출하였다. 특허 분석을 통해 인증과 거래 관련 토픽이 높은 비중을 차지하였다. 뉴스 기사 분석 결과, 사회적 관심은 암호화폐에 치중되어 있는 것으로 나타났다. 이러한 분석 결과와 의제설정이론에 근거하여 블록체인 관련 정책의제를 도출하였다. 본 연구는 대용량 텍스트 문서 분석의 자동화된 기법을 활용하여 분석을 효율적·객관적으로 수행하였으며, 블록체인 기술 동향과 사회적 관심도를 파악한 실증된 기초 분석 자료를 기반으로 정책의제를 제안하였다. 본 연구에서 제시된 정책의제는 향후 정책 결정과정에의 기초자료로 활용될 수 있을 것이다.
