This talk is part of the Data Science series


Abstract: In this talk, I will discuss work being conducted by one of my PhD students, Kalpesh Padia. Our goal is to visualize the critical events in a multi-participant narrative, either as a post-processing task, or in real time as the narrative unfolds. Critically, we identify ?choice points? where participants must choose between multiple actions. Our system is designed to show both the reality timeline: the narrative based on the actions chosen by participants; and all diagetic timelines: narratives that would have been possible if participants made different choices. We provide users with the capability of inspecting differences between reality and diagetic timelines, allowing them to select diagetic timelines of interest and identify where and how choices caused divergence between the diagetic and reality narratives.
Short Bio: Dr. Healey is a Professor in the Department of Computer Science, and the Goodnight Distinguished Professor of Analytics in the Institute for Advanced Analytics, both located at North Carolina State University in Raleigh, North Carolina. Dr. Healey?s research focuses on visualization and visual analytics, human visual perception, artificial intelligence techniques for intelligent visualization design, applied mathematical algorithms for large data management and analysis, and natural language processing and text analytics. Dr. Healey has participated in a wide range of real-world projects including physical science ensembles, cyber situation awareness, marine wildlife migration, risk analysis and communication for natural disaster events, sporting event visualization, and social media analytics. Dr. Healey holds a B.Math from the University of Waterloo in Waterloo, Canada, and a M.S. and Ph.D. in Computer Science from the University of British Columbia in Vancouver, Canada. Prior to joining North Carolina State University, Dr. Healey completed a postdoctoral fellowship in the Computer Science Division of the EECS Department at the University of California, Berkeley. He is an Associate Editor for ACM Transactions on Applied Perception, an ACM and IEEE Senior Member, and has published more than 50 peer reviewed articles in the computer science, cognitive psychology, and physical sciences venues.
