Investigating an online social network using spatial interaction models

Research output: Contribution to journalArticlepeer-review


Using a spatial interaction modeling approach, we investigate the German collegiate social network site StudiVZ. We focus on identifying factors that foster strong inter-institutional linkages, testing whether the acquaintanceship rate between institutions of higher education is related to various geographic and institutional attributes. We find that acquaintanceship is most significantly related to geographic separation: measuring distance with automobile travel time, acquaintanceship drops by 91% for each additional 100 min. Institution type and the former East-West German divide are also related to this rate with statistical significance.
