TITLE: Mining Billion-node Graphs: Patterns, Generators and Tools
SPEAKER: Christos Faloutsos (CMU)

ABSTRACT:
What do graphs look like? How do they evolve over time?
How to handle a graph with a billion nodes?
We present a comprehensive list of static and temporal laws,
and some recent observations on real graphs (like, e.g., ``eigenSpokes'').
For generators, we describe some recent ones,
which naturally match all of the known properties of real graphs.
Finally, for tools, we present ``oddBall''
for discovering anomalies and patterns,
as well as an overview of the PEGASUS system 
which is designed for handling Billion-node graphs,
running on top of the ``hadoop'' system.
