Abstract

Today, social networks systems have become more and more important. People have change their way to relate and communicate. Therefore, how to enhance contents and organization of a social network is a very important task. This way, we can help Virtual communities of practice (VCoP) to survive through time. VCoP are special kind of social network where the purpose is a key aspect. However, administrators are blind when trying to identify how to enhance the community. We propose a method which helps them by analyzing how purpose evolves through time. The approach has been experimentally tested in a real site with successful results. © 2009 Springer Berlin Heidelberg.
