Project KredibleNet Announces Two Publications

July 22, 2015

A. The project KredibleNet will present at the National Communication Association Annual Meeting to be held in Las Vegas, NE a major paper, announcing a key finding of the project. The paper is titled " Social differentiation and online collaboration: The dynamics of elite emergence on Wikipedia”. The paper proposes that on Wikipedia, increases in inequality contributions can over time lead to the creation of long lasting elites. The paper proposes an evolutionary model for Wikipedia editorial community development. Using a social differentiation lens and a community of practice perspective, we analyze 235 million editorial interventions to Wikipedia over a ten-year period (2001-2010). We reveal the presence of a leading elite, responsible for a majority of the editorial elite. Segmented regression reveals discrete evolutionary phases in elite emergence, which map onto Wenger's evolutionary model for communities of practice. Lagged regression indicates that an increase in collaborative structuration leads to the emergence of a quasi-stable, adhocratic elite.

The paper was co-authored by Sorin Adam Matei, Wuato Wei, Michael Zhu, Chuanhai Liu, Brian Britt and Elisa Bertino. The paper will be presented on November 11, at 11 am, in the Rio Conference Center, Room Brasilia 5.

B. The project KredibleNet will publish in August its second book, Transparency in Social Media, edited by the head of the CyberCenter, Elisa Bertino, by the Director for Computational Social Science, Sorin Adam Matei, both at Purdue University, and by Martha Russell, the head of the MediaX unit at Stanford University - The volume presents, in a synergistic manner, significant theoretical and practical contributions in the area of social media reputation and authorship measurement, visualization, and modeling. The book justifies and proposes contributions to a future agenda for understanding the requirements for making social media authorship more transparent. Building on work presented in a previous volume of this series,Roles, Trust, and Reputation in Social Media Knowledge Markets, this book discusses new tools, applications, services, and algorithms that are needed for authoring content in a real-time publishing world. These insights may help people who interact and create content through social media better assess their potential for knowledge creation. They may also assist in analyzing audience attitudes, perceptions, and behavior in informal social media or in formal organizational structures. In addition, the volume includes several chapters that analyze the higher order ethical, critical thinking, and philosophical principles that may be used to ground social media authorship. Together, the perspectives presented in this volume help us understand how social media content is created and how its impact can be evaluated.

The chapters demonstrate thought leadership through new ways of constructing social media experiences and making traces of social interaction visible.Transparency in Social Media aims to help researchers and practitioners design services, tools, or methods of analysis that encourage a more transparent process of interaction and communication on social media. Knowing who has added what content and with what authority to a specific online social media project can help the user community better understand, evaluate and make decisions and, ultimately, act on the basis of such information.
