Statistical analysis of user access graph from CiNii logs

Abstract

　The National Institute of Informatics has been developing an environment called "Integrated Log Platform" for cross-sectional analysis of logs from the Research Data Cloud provided by the Institute. In this presentation, we will introduce some of the results of log analysis using the functions of this platform, especially for CiNii logs. The features of this platform are (1) creating a user action label (vocabulary) for a log (URI), and (2) organizing access logs into meaningful units ("access graph"). This research shows the possibility of these functions to model the behavior of individual users.
