Contributions of the Symposium on Network Analysis in Natural Sciences and Engineering

After a general introduction to the emerging field of network analysis, we will focus on the analysis of group structure in dynamic networks. By defining groups based on similarity of neighborhoods rather than local density, nodes can be associated to roles representing structural positions in a network. A recently proposed relaxation of discrete role assignment allows for varying degrees of membership in such roles, and also points to dominant representatives within roles. The utility of this new approach is demonstrated on dynamic event data extracted from news reports on conflicts that took place in the Persian Gulf and on the Balkans.
