The module starts with an introduction to the fundamentals of digital communities and an overview of related concepts. The first part of the lecture is dedicated to the topic of networks and graph theory, followed by social networks and social network analysis and related applications. After that, additional concepts that are relevant to digital communities are presented, specifically recommender systems, which are discussed both at the mathematical and application-oriented level. The module concludes with an overview and discussion of the latest trends and developments in digital communities.

The topics of this module are taught in a classical lecture, which also envisages a related discussion between students and lecturer. Selected topics are further covered in an exercise course with frequent assignments. Each assignment contains several problems, which are to be solved by the students. During practical lessons, the solutions are then presented and discussed.

Students who have successfully finished this module have an overview of current and future concepts for digital communities. They have developed an understanding of the principles of graph theory and social network analysis, and have learned about the concepts of recommender systems, including content-based and collaborative filtering methods.
