A Social P2P Approach for Personal Knowledge Management in the Cloud

The massive access to the Cloud poses new challenges for the cloud citizens to use services overcoming the risks of a new form of digital divide. What we envision is a socially orchestrated cloud, i.e. an ecosystem where the users put their experience and know-how (their personal knowledge) at the service of the social cloud, where social networks articulate the assistance to users. With his scenario in mind, this paper introduces a peer-to-peer solution to the problem of sharing personal knowledge for social search. We propose a routing mechanism in a peers’ network, which uses both information about the social relation among peers and their personal knowledge. Finally, we deploy the proposal over Facebook as a support network.
