摘要:Abstract This work is geared to analyze informal learning processes in student conferences. In particular, it compares social network interactions occurring in conference-related Facebook pages - i. e. Taiwan-America Student Conference (TASC), Japan-America Student Conference (JASC) and Korea-America Student Conference (KASC) pages - within a period starting 30 days before and finishing 30 days after the application deadlines. This empirical study has been realized by adopting open source visualization tools and techniques freely available on the software market in order to perform Social Network Analysis (SNA) in a transparent and reproducible way. Such an analysis provides interesting information on interaction dynamics, emerging hot topics and sub-group formation of attending students.
