Traces of activity left by social media users can shed light on individual behavior, social relationships, and community efficacy. Tools and processes to analyze social traces are essential for enabling practitioners to study and nurture meaningful and sustainable social interaction. Yet such tools and processes remain in their infancy. We conducted a study of 15 graduate students who were learning to apply Social Network Analysis (SNA) to data from online communities. Based on close observations of their emergent practices, we derived the Network Analysis and Visualization (NAV) process model and identified stages where intervention from peers, experts, and an SNA tool were most useful. We show how the NAV model informs the design of SNA tools and services, education practices, and support for social media practitioners.

Abstract:
We investigate the practice of sharing short messages (microblogging) around live media events. Our focus is on Twitter and its usage during the 2008 Presidential Debates. We find that analysis of Twitter usage patterns around this media event can yield significant insights into the semantic structure and content of the media object. Specifically, we find that the level of Twitter activity serves as a predictor of changes in topics in the media event. Further we find that conversational cues can identify the key players in the media object and that the content of the Twitter posts can somewhat reflect the topics of discussion in the media object, but are mostly evaluative, in that they express the poster's reaction to the media. The key contribution of this work is an analysis of the practice of microblogging live events and the core metrics that can leveraged to evaluate and analyze this activity.

ABSTRACT: This paper documents the use of pictorial images in social network analysis. It shows that such images are critical both in helping investigators to understand network data and to communicate that understanding to others.

The paper reviews the long history of image use in the field. It begins with illustrations of the earliest hand-drawn images in which points were placed by using ad hoc rules. It examines the development of systematic procedures for locating points. It goes on to discuss how computers have been used to actually produce drawings of networks, both for printing and for display on computer screens. Finally, it illustrates some of the newest procedures for producing web-based pictures that allow viewers to interact with the network data and to explore their structural properties.

"About the Book: No less than a revolutionary transformation of the research enterprise is underway. This transformation extends beyond the natural sciences, where 'e-research' has become the modus operandi, and is penetrating the social sciences and humanities, sometimes with differences in accent and label. Many suggest that the very essence of scholarship in these areas is changing. The everyday procedures and practices of traditional forms of scholarship are affected by these and other features of e-research. This volume, which features renowned scholars from across the globe who are active in the social sciences and humanities, provides critical reflection on the overall emergence of e-research, particularly on its adoption and adaptation by the social sciences and humanities."

Space Planning for Online Community

Danyel A Fisher, Marc Smith, Tammara Combs Turner

Several years of consulting with online community hosts and managers have highlighted a variety of issues that recur across many online community development efforts. We summarize those issues in eight points that have functioned as useful guidelines to working with online communities, particularly within a corporate context. These recommendations focus on the location and purpose of the community, the monitoring of social activity within the space, the provision of feedback to participants and the organization and maintenance of the space. While this collection is particularly focused on issues relevant to community organizers closely involved in starting, maintaining or growing online communities, its principles are generally applicable for analyzing and understanding the dynamics within a variety of communities.
