E-mail user roles identification using OWL-based ontology approach

Social networks as structures reflecting social relations between individuals or organizations are often studied in order to identify roles of actors of the network. Classification of roles played by the actors can be very informative because it gives us the complete overview of the network allowing for understanding how the network is organized and how it is going to behave in front of certain external or internal events. In the paper we present how this task can be accomplished with support of OWL-based ontology and related tools. As a sample social structure we use a network of e-mail users.
