WWW 2015 Workshop: Diffusion, Activity and Events in Networks

In recent years, there has been an increasing effort on performing empirical studies, developing realistic models, and designing learning and inference algorithms to understand, predict, and control diffusion, activity and events over networks. In this context, there is a wealth of research problems and high-impact applications in social networks, information systems, marketing, epidemiology, business intelligence, and national security. For example, identifying influential users in social networks can become a multi billion dollar industry; detecting the spread of rumors and misinformation can improve information reliability and trustworthiness; designing user interfaces that mitigate information overload can increase users' engagement and improve workers' productivity; early detection and control of disease spreads can save lives.

Progress has been made possible in part due to the increasing availability and granularity of large-scale activity data from the Web and social media, which, in principle, allows for understanding and modeling not only macroscopic activity but also microscopic (node-level) one. To this aim, a bottom-up data-driven approach has been typically considered, which starts by tracking how particular behavior, ideas, pieces of information, products, diseases, or contagions in general spread locally from node to node apparently at random to later produce global, macroscopic patterns at a network level. However, this bottom-up approach also raises significant modeling, algorithmic and computational challenges which require leveraging complex methods and techniques from machine learning, probabilistic modeling, event history analysis and graph theory, as well as the nascent field of network science.

Topics of Interest

Topics of interest for the workshop include (but are not limited to) the following:

  • Cascading processes in networks
  • Modeling and shaping social activity in networks
  • Metrics, models and measurement of influence in networks
  • Homophily, social contagion and causality
  • Information diffusion in social networks
  • Rumors, misinformation, and anti-spam detection
  • News diffusion and data-driven journalism
  • Propagation of revolutionary unrest in networks
  • Mobility patterns and traveling in networks
  • Disease dynamics and vaccination in networks
  • Virtual currenty networks
  • Games in networks
  • Trust in networks

Submission Guidelines

Papers must be formatted according to ACM SIG Proceedings template (http://www.acm.org/sigs/publications/proceedings-templates) and style files to fit within 6 pages, including references, diagrams, and appendices if any. A submitted paper must be self-contained and in English. PDF files must have all non-standard fonts embedded.

Papers should be submitted by email to manuelgr@mpi-sws.org, with the title of "[WWW 2015 Workshop]: $paper-title".

The review process will be single-blind. Therefore, please include the author and affiliation information in the submission. Each submission will be reviewed by at least three reviewers. Papers must report original research not accepted or under submission to any peer-reviewed conference. Previous submissions in venues with no formal proceedings or as posters are allowed, but must be indicated.
