Examination of International Collaborative Research Status and Co-Authorship Network Visualization of Korean Researchers in the Computer Field

Abstract

Background/Objectives: According to a recent WEF report, Korea's competitiveness ranking in the Information & Communication Technology (ICT) sector, which provides the foundation technology of the Fourth Industrial Revolution, ranks among the highest in the world. It is very important to analyze the research behavior in the computer field, which is a core discipline in the ICT field. In this paper, to investigate the current status of international joint research by computer researchers in Korea, this study analyzed the current status of cooperative relations between domestic and foreign author-affiliated institutions by using the papers of Korean computer researchers published in core journals. Methods/Statisticalanalysis: Author's organization and country information were extracted from the collected papers by preprocessing. Based on these, the rankings by institution, country ranking, and the status of collaboration between countries and institutions were statistically analyzed. Thirdly, a network was created and visualized on a map based on the co-authorship between the author's institution and the country of each article examined in the previous step. Findings: The findings of this study are as follows. First, popular SCI journals preferred by Korean researchers were analyzed. Second, the statistics of author's affiliated institutions (author's organization, author's country) were counted by year of publication and period of year of publication. The rankings of domestic and overseas author-affiliated institutions and the rankings of countries were calculated. In the case of the United States, which has the highest rate of deductions, the rankings were also calculated by US states. Third, international collaborative networks of Korean computer researchers were created and visualized by author-level institutions and country levels. Improvements/Applications: The results of this study can help us to identify trends in computer researchers and research institutes in Korea. To this end, it is necessary to identify and collect key academic resources in the computer field as a whole.
