"The Intranet tends to follow trends from the web, and social networking is
no exception" [Nielsen Norman Group 2009]
"It's better to structure information according to how people use it, rather
than what department owns it"[Jakob Nielsen 2009]
enterprise 2.0
"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".
[Mc Afee 2009]

• interactions between actors
• affiliation between actors

• Strong links: close collaborators
• Weak links professional acquaintances
• Potential links: professional proximity
• Absent relationships: remainder of the network
Social capital
"resources embedded in one's social networks, resources that can be accessed or mobilized through ties in the networks" [Lin 2008]

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
Open problem: using analysis metrics to leverage social intranet usability
