Fast Discovery of Connection Subgraphs

Christos Faloutsos, Kevin S. McCurley, and Andrew Tomkins

We define a connection subgraph as a small subgraph of a large graph that best captures the relationship between two nodes. The primary motivation for this work is to provide a paradigm for exploration and knowledge discovery in large social network graphs. We present a formal definition of this problem, and an ideal solution based on electricity analogues. We then show how to accelerate the computations, to produce approximate but high-quality connection subgraphs on very large (disk-resident) graphs.
