This study contributes to the understanding of cultural forms, inspired by Cassirer’s notion of a general function manifesting in the many particular expressions of human culture. The special case of cybersemiotics (a newly established scientific discipline) is studied as a social system to make sense of how it operates as a viable cultural form. The study uses citation network analysis to map out the boundaries and communications of the cybersemiotic discipline, and then delves into its contents to qualitatively investigate selected parts of the network structure. A framework for studying and comparing cultural forms is developed.
