Characteristics of large group support systems

In this paper, we present an evaluation of large group support systems and literature in three fields: group support systems (GSS), computer supported cooperative work, and online self-organizing social systems. In addition to literature, we investigated over 25 large group systems (18 are presented here). Since GSS research has typically specialized in smaller groups, this research serves to categorize groupware applications and introduce GSS researchers to large groupware concepts and the large groupware landscape.
