Quantitative analysis of Role behaviour and time evolution in usenet groups — •Eleni Hitchinson1 and Christian von Ferber1,2 — 1Applied Mathematics Research Centre, Coventry University, UK — 2Physikalisches Institut, University Freiburg
A number of usenet groups have a long history where individual users are found to participate over long time ranges. These groups therefore offer the possibility to test hypotheses like e.g. preferential attachment scenarios on such time scales. Our focus is in particular on developing quantitative indicators for the type of discussion (e.g. technical or philosophical) and the self-defined roles of the participants. Analysing technical discussion we identify time evolving network motives that describe ’expert’ members who answer many questions while in ’philosophical’ discussions some members occur who initiate a multitude of discussions. In this way we observe quantitatively how these roles evolve and may change with time.
