Abstract

As time goes by, the amount of data is increasing regardless of government, business, domestic or overseas. Accordingly, research on big data is increasing in academia. Statistics is one of the major disciplines of big data research, and it will be interesting to understand the research trend of statistics through big data in the growing number of papers in statistics. In this study, we analyzed what studies are being conducted through abstract data of statistical papers in Korea and abroad. Research trends in domestic and international were analyzed through the frequency of keyword data of the papers, and the relationship between the keywords was visualized through the Word Embedding method. In addition to the keywords selected by the authors, words that are importantly used in statistical papers selected through Textrank were also visualized. Lastly, 10 topics were investigated by applying the LDA technique to the abstract data. Through the analysis of each topic, we investigated which research topics are frequently studied and which words are used importantly.

시간이 갈 수록, 정부, 기업, 국내, 해외를 막론하고 데이터의 양이 증가하고 있다. 이에따라 학계에서도 빅데이터에 대한 연구들이 늘어나고 있다. 통계학은 빅데이터 연구의 중심이 되는 학문들 중 하나이며, 늘어나는 통계학 분야 논문 빅데이터를 통해 통계학의 연구동향을 파악해 보는 것도 재미있을 것이다. 본 연구에서는 국내와 해외의 통계학 논문들의 초록데이터를 통해 어떤 연구들이 이루어지고 있는지 분석을 진행하였다. 저자들이 선정한 논문들의 키워드 데이터 빈도를 통해 국내외 연구 동향을 분석하였고, Word Embedding 방법을 통해 해당 키워드들의 관계성을 시각화 하였다. 여기서 저자들이 선정한 키워드들 외에 Textrank를 통해 선정된 통계학 분야 논문들에서 중요하게 사용되는 단어들도 추가적으로 시각화 하였다. 마지막으로 초록 데이터에 LDA 기법을 적용하여 10가지 토픽을 알아보았다. 각 토픽들에 대한 분석을 통해 어떤 연구 주제들이 자주 연구되며, 어떤 단어들이 중요하게 사용되는지 알아보았다.
