Lectures take place both in presence and online (on Microsoft Teams 668AA 21/22 - SOCIAL NETWORK ANALYSIS - For the setup guide refer to the UNIPI documentation)
All lectures will be recorded and made available along with the slides/notebooks used in class (you can find them under the "Files" tab in the Team channel).For each lecture are reported the book chapters/papers to be studied: while some of them are mandatory (i.e., most book chapters and surveys) others are suggested readings.
