Web Mining Lab Showcased Twitter Project at CityU Big Data Exhibition

The project, titled “Modeling and Visualizing Big Data on Twitter”, attracted keen attention at the Big Data Exhibition held on October 14, which was a highlight event to celebrate the 30th anniversary of City University of Hong Kong. The project was a joint effort among the Lab, Microsoft Research Asia, Nanyang Technological University of Singapore, and Hong Kong University of Science and Technology. Nearly 100 million tweets, collected from Twitter during the U.S. presidential election in 2012, were analyzed based on an expanded model of Zhu’s zero-sum game theory of agenda-setting and visualized through a RiverTheme scheme developed at Microsoft Research. Details of the project have been reported in Xu et al. (2013). Visual analysis of topic competition on social media. IEEE Transactions on Visualization and Computer Graphics , 19(2), 2012-2021. The video visualization shown in the Exhibition is available on YouTube.
