Modelling the strength of relations in telecommunication social networks

Theoretical modelling and empirical studies on networks of various entities have been a subject of a large body of recent research. Methods from the network analysis are applied in such domains as epidemiology, city planning, marketing and social networks. A social network is a structure consisting of individuals and ties between these individuals. The research on this structure applies social network analysis, with a set of methods, to identify local and global patterns, recognise influential users and examine network dynamics. Based on the telecommunication data from the Call Detail Records (CDRs), a social network involves individuals (represented by phone numbers) connected by ties based on services used between these individuals. The paper focuses on the problem of modelling relations (ties) between the telecommunication users in a social network and proposes a method for measuring a strength of a social relation based on CDRs.
