The course introduces students to Web science with a focus on how the Web works, types of Web data, and how to generate effective visualizations for Web data (e.g., social networks). The course covers basic principles and tools for understanding and visualizing Web data. It focuses heavily on project work that aims to give students hands-on experience with handling Web data. Because Web science is interdisciplinary by nature, this course connects students to different disciplines such as social science, computer science, and information science. At the end of the course, students should be able to apply Web mining techniques on and draw insights from real world data.
