Our digital, social and civic life is increasingly powered by data. What we read, watch and buy is shaped by customization algorithms that are built based on a trove of digital behavioral data (e.g., Facebook 'likes' and YouTube viewing history). This class will provide a broad picture of how our internet behavior is being tracked and analyzed for user psychology and public opinion as well as the implications of data mining for privacy and civic engagement. The course includes workshops in technical skills for social media data mining and visualization.
