Computational Social Media

The course will present a human-centered view of computational social media. It uses a multidisciplinary approach and integrates concepts from media studies, multimedia information systems, machine learning, and network science to present the socio-technical fundamentals needed to understand user motivations and behavior, and analyze content in platforms like Twitter/X, Instagram, YouTube, and TikTok. Students will become familiar with computational approaches for classification, discovery, and interpretation of phenomena in social media.

The content is organized around trends in social media, introducing computational models of general applicability.
