Persistent Roles in Online Social Networks [chapter]

Matt Revelle, Carlotta Domeniconi, Aditya Johri
2016 Lecture Notes in Computer Science  
Users in online social networks often have very different structural positions which may be attributed to a latent factor: roles.  ...  In this paper, we analyze dynamic networks from two datasets (Facebook and Scratch) to find roles which define users' structural positions.  ...  Any opinions, recommendations, findings, or conclusions expressed in this material are those of the authors and do not necessarily reflect the views of NSF.  ...

Directed Networks of Online Chats: Content-Based Linking and Social Structure

V. Gligorijevic, M. Skowron, B. Tadic
2012 2012 Eighth International Conference on Signal Image Technology and Internet Based Systems  
Online chats are recently shown to result in longterm associations among users, represented by a directed weighted network, similar to dialogs in online social networks.  ...  We consider the persistent network which emerges from user-touser communications found in the empirical dataset from IRC Ubuntu channel.  ...  The emergent persistent network of chats has a hierarchical network organization, in which both emotions and type of messages play a role.  ...

Structure and stability of online chat networks built on emotion-carrying links

Vladimir Gligorijević, Marcin Skowron, Bosiljka Tadić
2013 Physica A: Statistical Mechanics and its Applications  
In particular, we find self-organized dynamics with long-range correlations in user actions and persistent associations among users that have the properties of a social network.  ...  High-resolution data of online chats are studied as a physical system in laboratory in order to quantify collective behavior of users.  ...  play an essential role in building a persistent techno-social structure.  ...

Network Communities: Something Old, Something New, Something Borrowed ..

Elizabeth D. Mynatt, Vicki L. O'Day, Annette Adler, Mizuko Ito
1998 Computer Supported Cooperative Work (CSCW)  
Network communities are robust and persistent communities based on a sense of locality that spans both the virtual and physical worlds of their users.  ...  Collaboration has long been of considerable interest to both designers and researchers in the CHI and CSCW communities.  ...  So the sense of persistence must be addressed in some manner in each part. Once a network community is perceived to be persistent, ecological changes can be comprehended as social acts.  ...
