Call for papers

The International Conference on Social Informatics (SocInfo) is an interdisciplinary venue that brings together researchers from informatics and social sciences to help fill the gap between the two communities. The goal of the conference is to contribute to the definition and exploration of common methodologies and research goals that encompass the objectives and motivate the two disciplines. More information.

Talk: Paper Presentation at Sunbelt

S
andra presented a paper at the XXXIV Social Networks Conference organized by INSNA. The working paper is joint work with Pablo Barberá and it is titled “The Self-Organization of Mass Political Protests in the Absence of Media Freedom”

Talk: Computational Social Science Panel

Other invited panelists included Noshir Contractor (Northwestern Univeristy), Steven Corman (Arizona State University), Marshall Scott Poole (University of Illinois at Urbana Champagne) and Kevin Crowston (Syracuse University).

New Article: Big Data and Human Geography

González-Bailón, S. (2013). “Big Data and the Fabric of Human Geography”, Dialogues in Human Geography, vol. 3 no. 3 292-296

Abstract: Digital data tracking what we do, the time and place of our actions, and the chains of interdependence that link those actions together, help us draw a richer picture of human geography as it unfolds in its multiple layers. This commentary briefly illustrates the type of maps and models we can build with that data as well as some important challenges that arise from their complexity and unsolved validity concerns.

New Article: Diffusion Dynamics

Entropy 
Baños, R., Borge-Holthoefer, J., Wang, N., Moreno, Y., and González-Bailón, S. (2013). “Diffusion Dynamics with Changing Network Composition”, Entropy (special issue on Social Networks and Information Diffusion), 15(11): 4553-4568

Abstract: We analyze information diffusion using empirical data that tracks online communication around two instances of mass political mobilization that took place in Spain in 2011 and 2012. We also analyze protest-related communications during the year that elapsed between those protests. We compare the global properties of the topological and dynamic networks through which communication took place, as well as local changes in network composition. We show that changes in network structure underlie aggregated differences on how information diffused: an increase in network hierarchy is accompanied by a reduction in the average size of cascades. The increasing hierarchy affects not only the underlying communication topology but also the more dynamic structure of information exchange; the increase is especially noticeable amongst certain categories of nodes (or users). Our findings suggest that the relationship between the structure of networks and their function in diffusing information is not as straightforward as some theoretical models of diffusion in networks imply.

Workshop: Social Media and Political Participation

A one-day workshop was organized today by the NYU’s Center for Social and Political Behavior. Other invited participants included faculty members and graduate students from Princeton, NYU, GWU, UNC, and Berkman.
