The model defines the organization of a system in terms of entities and groups, each one with a well-defined interface, that mediates all the interactions. Entities can dynamically enter and leave groups, and distinct forms of communication...
In this paper we discuss how the concept of implicit groups is used to build and manage extended user profiles enabling an easier way to supply personalized features and/or information, and guide their dynamic updating. This approach extends the individual user profiles, which are explicitly defined by the user in typical interactive applications and environments, with additional information that...

Due to this, it becomes necessary to help users to better filter and select the information that will be more useful to them...
