Title: Event-based Multi-dimensional Social Network Analysis and Health-related Online Communities
Speaker: Prof. John Yen, (University Professor of Information Sciences and Technology, The Pennsylvania State University
Time: 14:20, July 01 (Fri), 2011
Place:  CSIE Building R103

The rapid explosion of online social networks through social network sites (e.g., Facebook) and social media (e.g., Twitter) raises many important questions regarding the dynamic behaviors of these networks.  While principles such as “prefential attachments” have shown to be applicable to model the growth of a wide range of complex networks, modeling the evolution of networks involving multiple dimensions (i.e., multiple types of links) remain a challenge.  In this talk, I will first discuss an approach to multi-dimensional network modeling using “events” to simulate and predict the interactions between different dimensions of networks and its application to social networks among NGO’s.  I will then discuss how the notion of “events” can also be useful to model the dynamic evolution of co-authorship network and to recommend the creation of new ties.  Finally, I will discuss an event-based sentiment analysis about the impact of online communities to cancer survivors.
