Social Network Services as Data Sources and Platforms for e-Researching Social Networks

Social network services such as Facebook provide new data for social science research into, for example, the role of individual characteristics in friendship formation and the diffusion of tastes in social networks. This article assesses the potential of social network services for social science research in two ways. First, it is argued that social scientists conduct hyperlink analysis differently to applied physicists and researchers from the library and information sciences, and face constraints (relating to theory, methods and availability of appropriate tools) that are not encountered in the other disciplinary approaches. However, the constraints regarding theory and methods are less likely to be faced by researchers of online social networks, and for this reason, the rise of Facebook and other similar services is a potential boon for empirical social scientists interested in networks. The second part of the article focuses specifically on the availability of research tools, and it is argued that social network services may eventually serve as e-Research platforms for delivering social network analysis tools.
