A Study on relationship between the Information Science and other fields based on keyword analysis

Abstract

　In this study, relationships between the Information Science and other fields were investigated in terms of keywords extracted from research themes of each researcher. First, procedure for extracting keywords from the database of Directory of Researchers was presented. As an index measuring the relationship, we introduced a coefficient of normalized complete congruence and further applied the Correspondence Analysis method to analyze the relations between the three items of the so-called Information Science and other related research fields at Japanese universities.
