Abstract:

Given a large graph, like who-calls-whom, or who-likes-whom, what behavior is normal and what should be surprising, possibly due to fraudulent activity? How do graphs evolve over time? How does influence/news/viruses propagate, over time? We focus on three topics: (a) anomaly detection in large static graphs (b) patterns and anomalies in large time-evolving graphs and (c) cascades and immunization.

For the first, we present a list of static and temporal laws, including advances patterns like ‘eigenspokes’; we show how to use them to spot suspicious activities, in on-line buyer-and-seller settings, in FaceBook, in twitter-like networks. For the second, we show how to handle time-evolving graphs as tensors, how to handle large tensors in map-reduce environments, as well as some discoveries such settings.

For the third, we show that for virus propagation, a single number is enough to characterize the connectivity of graph, and thus we show how to do efficient immunization for almost any type of virus (SIS – no immunity; SIR – lifetime immunity; etc)
We conclude with some open research questions for graph mining.

The WWW conference series is the premier conference on research and development on Web technologies and the Web "ecosystem". It has a long tradition of reporting ground-breaking results, e.g., the page rank paper was published by Brin and Page in WWW 1998 in Brisbane, among many others. It features a wide range of keynotes such as Tim Berners-Lee, A. P. J. Abdul Kalam (former president of India, the "People's President"), Christos H. Papadimitriou,  Vint Cerf, and Carl Malamud, among other well known names.
