In this study, we conducted a web questionnaire survey of 120 students at a local private university, and although it was exploratory, we did text mining on free text. As a result of the correspondence analysis, "General Users" used apps with a large amount of information but a small volume per content. "Risk Users" used apps that were expected to be used for a long time once logged in. Based on this research, we would like to increase the number of collaborators and conduct a survey.
