GCIS INTELLIGENCE UPDATE: The rise of social media has allowed people to connect and re-connect with friends, colleagues and family from across the world. A new paper by University of 
Minnesota computer scientists in the College of Science and Engineering provides insights into how the analysis of our social networking interactions could discover things like the emergence or decline of leadership, changes in trust over time, and migration and mobility within particular communities online.
The paper, "Computational Modeling of Spatio-temporal Social Networks: A Time-Aggregated Graph Approach," was co-authored by computer science and engineering professor Shashi Shekhar and research assistant Dev Oliver. The researchers recently presented the paper at a national workshop hosted by the University of California, Santa Barbara, in conjunction with the National Science Foundation and Army Research Center.
In most cases, social network analysis today is limited to discovering friend connections, community leaders and outlines, influential people and personal friend recommendations using a static or snap-shot method.
