Existing collaboration support systems cope poorly with today's working environments. Although they offer functionalities to overcome cognitive overhead, these prove to be insufficient in data-intensive situations. In this paper, we identify the main causes of cognitive complexity in contemporary collaboration support systems and present the approach adopted in the Dicode project to address such concerns. We discuss how Dicode mitigates the effects of cognitive overload issues through an adaptive collaboration support infrastructure that allows organizational aspects of the discourse to change according to the user's needs, interests and specific tasks during the evolution of the collaboration.
