Abstract
Given a large graph with several millions or billions of nodes and edges, such as a social network, how can we explore it efficiently and find out what is in the data? In this demo we present Perseus, a large-scale system that enables the comprehensive analysis of large graphs by supporting the coupled summarization of graph properties and structures, guiding attention to outliers, and allowing the user to interactively explore normal and anomalous node behaviors.
Specifically, Perseus provides for the following operations: 1) It automatically extracts graph invariants (e.g., degree, PageRank, real eigenvectors) by performing scalable, offline batch processing on Hadoop; 2) It interactively visualizes univariate and bivariate distributions for those invariants; 3) It summarizes the properties of the nodes that the user selects; 4) It efficiently visualizes the induced subgraph of a selected node and its neighbors, by incrementally revealing its neighbors.
In our demonstration, we invite the audience to interact with Perseus to explore a variety of multi-million-edge social networks including a Wikipedia vote network, a friendship/foeship network in Slashdot, and a trust network based on the consumer review website Epinions.com.

On the Multichromatic Number of s-Stable Kneser Graphs
For positive integers n and s, a subset Sï [n] is s-stable if sï |i-j|ï n-s for distinct i,j∈S . The s-stable r-uniform Kneser hypergraph KGrn,ks-stable is the r-uniform hypergraph that has the collection of all s-stable k-element subsets of [n] as ...
Adjacent vertex-distinguishing edge and total chromatic numbers of hypercubes
An adjacent vertex-distinguishing edge coloring of a simple graph G is a proper edge coloring of G such that incident edge sets of any two adjacent vertices are assigned different sets of colors. A total coloring of a graph G is a coloring of both the ...
Forbidden Subgraphs and Weak Locally Connected Graphs
A graph is called H-free if it has no induced subgraph isomorphic to H. A graph is called $$N^i$$Ni-locally connected if $$G[\{ x\in V(G): 1\le d_G(w, x)\le i\}]$$G[{x?V(G):1≤dG(w,x)≤i}] is connected and $$N_2$$N2-locally connected if $$G[\{uv: \{uw, vw\...
