During the past years, data science played a pivotal role in many social issues such as the spreading of (mis)information online, echo chambers, bot detection, mobility patterns, and resilience.
The course will introduce advanced topics of networks science and diffusion models and, thanks to the complex systems approach, we will extract knowledge from data by exploiting a complexity-driven (e.g., dynamic processes on complex networks) approach.
In the first part we will explore the foundational aspects and advanced topics of complex systems (multilayer networks, percolation, time-varying graphs), while in the second part, we will apply those concepts to state-of-the-art cases on massive datasets, ranging from the effect of feed algorithms on social dynamics up to patterns of human mobility, passing through information operations, and bot detection.
