Studying Online Social Networks


  • Laura Garton,

    Corresponding author
    1. Candidate in the Department of Sociology at the University of Toronto. Her dissertation is based on a whole network study of computer-mediated communication within an organizational context. Applying a social network perspective, she examines how the introduction of a multimedia space technology creates new opportunities and at the same time new constraints on the relations and interaction patterns among geographically separated work groups.

When a computer network connects people or organizations, it is a social network. Yet the study of such computer-supported social networks has not received as much attention as studies of human-computer interaction, online person-to-person interaction, and computer-supported communication within small groups. We argue the usefulness of a social network approach for the study of computer-mediated communication. We review some basic concepts of social network analysis, describe how to collect and analyze social network data, and demonstrate where social network data can be, and have been, used to study computer-mediated communication. Throughout, we show the utility of the social network approach for studying computer-mediated communication, be it in computer-supported cooperative work, in virtual community, or in more diffuse interactions over less bounded systems such as the Internet.
