【Abstract】 A closed triad is a group of three people who are connected with each other. It is the most basic unit for studying group phenomena in social networks. In this work, we study how closed triads are formed in dynamic networks. More specifically, given three persons, what are the fundamental factors that trigger the formation of triadic closure? There are various factors that may influence the formation of a relationship between persons. Can we design a unified model to predict the formation of triadic closure? Employing a large croblogging 
network as the source in our study, we study how user demographics and network topology influence the process of triadic closure. We also present a probabilistic graphical model to predict whether three persons will form a closed triad in dynamic networks. The experimental results on the microblogging data demonstrate the efficiency of our proposed model for the prediction of triadic closure formation.

Short bio:  Prof. Xiaoming Fu received his Ph.D. in computer science from Tsinghua University, Beijing, China in 2000. He was then a research staff at the Technical University Berlin until joining the University of Goettingen, Germany in 2002 as assistant professor, where he has been a professor in computer science and heading the Computer Networks Group since the beginning of 2007. He has spent research visits at universities of Cambridge, Columbia, UCLA, Tsinghua, Nanjing, Fudan, Uppsala, and UPMC. Prof. Fus research interests include network architectures, protocols, and applications. He is currently an editorial board member of IEEE Communications Magazine, IEEE Transactions on Network and Service Management, Elsevier Computer Networks, and Computer Communications, and has served on the organization or program committees of  leading conferences such as SIGCOMM, CoNEXT, MOBICOM, MOBIHOC, INFOCOM, ICNP, ICDCS, and COSN. He has served as secretary (2008-2010) and vice chair (2010-2012) of the IEEE Communications Society Technical Committee on Computer Communications (TCCC), and chair (2011-2013) of 
the Internet Technical Committee (ITC) of the IEEE Communications Society and the Internet Society (now chairing its awards committee). He is an IEEE Distinguished Lecturer, an IEEE Senior Member and an ACM member. He has been involved in EU FP6 ENABLE, VIDIOS, Daidalos-II and MING-T projects and is the coordinator of  EU FP7 GreenICN, MobileCloud and CleanSky projects as well EU H2020 ICN2020 project.
