The course gives an introduction to the theory of social networks in business informatics. It does not only deal with the characteristics of individuals or organizations, but also with the relationships and structure of these relationships between individuals and organizations. The corresponding theories and concepts from economics, sociology, business informatics and organizational research will be introduced. In addition, methods from computer science and graph theory are taught that allow social networks to be evaluated quantitatively. Basic quantitative methods will be used to evaluate simple data sets with freeware/shareware programs, e.g. friendship networks like those found on Facebook.
