Speaker: Nan Cao, IBM T. J. Watson Research Center
Social media, like Twitter, has been widely used for disseminating and exchanging information, opinions, and emotions about events happening across the world. In this talk, I introduce visualization tools for tracing the process of information diffusion over social media. In particular, I highlight the social, spatiotemporal processes of diffusion based on novel designs driven by various visual metaphors. These designs facilitate an understanding of the 5W elements of information diffusion, including who, when, where, and how various types of information (e.g., sentiments and topics) are dispersed for large-scale events, such as election campaigns and earthquakes, as a tool witnessing today's information consumption and dispersion in the wild.
