We present TOURVIZ, a interactive system for visualizing and making sense of large network datasets. Given a set of user-specified nodes of interest, TOURVIZ integrates 1) novel algorithms to find the best sub graphs that succinctly connect these nodes, and 2) visualization and interaction features that help people explore such sub graphs. We will demonstrate TOURVIZ's usage and benefits using the...
How closely related are two nodes in a graph? How to compute this score quickly, on huge, disk-resident, real graphs? Random walk with restart (RWR) provides a good relevance score between two nodes in a weighted graph, and it has been successfully used in numerous settings, like automatic captioning of images, generalizations to the "connection subgraphs", personalized PageRank, and many...
