Email as Spectroscopy: Automated Discovery of Community Structure within Organizations. Communities and Technologies, pp. 81-96. Abstract: We describe a methodology for the automatic identification of communities of practice from email logs within an organization. We use a betweeness centrality algorithm that can rapidly find communities within a graph representing information flows. We apply this algorithm to an email corpus of nearly one million messages collected over a two-month span, and show that the method is effective at identifying true communities, both formal and informal, within these scale-free graphs. This approach also enables the identification of leadership roles within the communities. These studies are complemented by a qualitative evaluation of the results in the field. http://www.hpl.hp.com/research/idl/papers/email/email.pdf Emilie Le 16 nov. 05 à 19:43, Chris Diehl a écrit : > ***** To join INSNA, visit http://www.insna.org ***** > > Dear SOCNETers, > > I am interested in the problem of inferring the management > hierarchy of an > organization from observed email exchanges.
