In order to analyze and compare the intellectual structure of information organization research in Japan and Korea, this study has carried out frequency analysis and network text analysis of research articles published in the last two years. Analysis showed that the Japanese information organization area has a high frequency of research centered on the concepts of “catalog” and “classification”. In particular, “catalog” is seen to have a high figure in degree centrality by network text analysis, it can be said that the “catalog” concept has extensive connections with a diverse range of subjects in the area of information organization. On the other hand, the Korean information organization research area showed a high frequency and connectivity of subjects related to “classification” rather than “catalog”. The “classification” concept is seen to have extensive connections with other various subjects in the Korean information organization research area.
