Social Network Analysis on Dynamic Digital Networks


Social Network Analysis (SNA) is a well established method in sociology. With the advent of the World Wide Web and growing computational power interests grow in analyzing large sets of network data over time. We apply graph theory, dynamic network analysis methodologies and advanced approaches in Web Science to analyze dynamic patterns of human interaction expressed by traces left large scale information systems. Our annual lecture "Web Science" and our "Web Science Seminar" contribute to a sound theoretical basis for student and research work. A couple of prototypes provide support user communities in getting to know their own networks.

A relevant reading list on social network analysis

A typical result of our recent research is the dynamic comparison of computer science communities. A computer science conferenced can be compared by time series analysis for typical social network growth patterns like density, diameter, clustering coefficient, largest connected component, average path length and maximum betweenness. In our example we compare the EC-TEL community with the ICALT and the ICWL community. We have a graph visualization of the EC-TEL community over time, a list of key members in the community by apperance to the event, continuity of the conference by publication numbers resp. frequency of contributions and the time series analysis visualization. Such posters can be produced for any conference and journal series in the DBLP index.
