Abstract

A Collaborative User Experience Technical Report: more about CUE...

Expertise Location Servers are usually isolated behind corporate firewalls because they mine sensitive documents such as e-mails. Professional networking sites expose expertise information to non-collocated social networks, but are limited to keywords input by users. We introduce a data structure called “Expertise Dictionary”, which encapsulates automatically mined expertise keywords for transport across firewalls. The Expertise Dictionary naturally leads to unique soft-state based server-less architectures, eliminating the costs associated with hosted servers. Not having a centralized server gives experts complete control & privacy in generating expertise keywords. This system architecture can be generalized to distributing other kinds of information in social networks.
