Nocturnal Vision • Messenger asa SocialInfrastructure for Communities. • Decentralized social information sharing. • Data propagates to 1-hop: a user’s contacts2-hop: contacts’ contacts3-hop: contacts’ contacts’ contactsand so on • Collaborative and personalized web search. • Each user stores information locally in a database My contacts’ contacts My Contacts: small community

  5. Messenger as a Social Infrastructure for Communities. • Social communities are a powerful tool but social connections are hard to elicit from users. • MSN messenger is an existing large social network • Solves the bootstrapping problem. • Yields effective communities (see poster).

  6. Decentralized social information sharing. • No central repository – P2P paradigm • Personalization: Each user has distinct data • Privacy: User information propagates only to trusted peers • Trust: Information is pulled only from trusted peers

  7. Collaborative and personalized web search. • Things you can do with Nocturnal: • Share URL ratings among Messenger peers • Collaborative web spam filtering • Exchange reviews and recommendations • A browser enhanced with our toolbar uses the local database to filter search results and to give peer-recommended URLs higher importance.

  8. Research Challenges • Properties of Messenger-Based Communities and Implications on Information Sharing and Dissemination. • Trust and Reputation on a Social Network. • Collaborative and Personalized Search: information gathering, filtering, aggregation and ranking.
