Our research themes
• An information value chain of producers & consumers yields an assured information sharing
lifecycle
• Policies for trust, access and use grounded in
sharable semantic models operating in a
service oriented architecture accelerate sharing
• New integration and discovery techniques are
required to assure information quality and
privacy
• Modeling, analyzing and exploiting social
networks and incentives for sharing
