CoMeMo-Community is a system that is designed to support knowledge evolution in a community. It is based on two ideas. One
is associative representation for facilitating externalization of both personal and community knowledge. The other is visualization
of knowledge interaction based on the talking-alter-egos metaphor.
In this paper, we present how these ideas are incorporated into the CoMeMo-Community system and report preliminary experimentation
with it. We also discuss how CoMeMo-Community helps us to understand community.
