than what department owns it"[Jakob Nielsen 2009]

"the use of emergent social software platforms within companies, or between companies and their partners or customers" [Mc Afee 2006]

"emergent social software platforms"

"digital environments in which contributions and interactions" are:

• "globally visible and persistent over time"• performed with social softwares that "enable people

to rendezvous, connect or collaborate through computer-mediated communication and to form online communities"

• emergent, freeform, with "patterns and structure inherent in people’s interactions".

Analyzing intranet of people

sound great! but… what for?

maintain strong links

• exploit the semantic of links to filter notifications

• highlight influent actors and popular resources not yet mobilized

strengthen weak links

highlight valuable weak links that provide access to relevant assets and opportunities

filter potential social capital and

connect communities and people

that should collaborate

bridge social gaps
