Research Abstract

Citation network analysis has been used to comprehend an overview of academic research. Three methods, co-citation, bibliographic coupling, and direct citation, are known, but there are few studies to compare those methods with real data. This research quantitatively revealed characteristics of them. Citation networks were created with those three methods, and evaluated their relevance, effectiveness, and efficiency. A method giving weight on links are proposed and also analyzed. It is found that direct citation is superior to the others in detection of emerging research fields. Term distribution, interdisciplinarity, citation lag were also investigated.
