Title: Large Attribute Graph Clustering

Abstract: 

In recent years, there exist many large graphs available including
social networks, sensor networks, biological networks, etc. Such large
graphs need to be fully investigated. Graph clustering has shown its
effectiveness in analyzing and visualizing large graphs.  The goal of
clustering a large graph is to partition vertices into different
clusters based on various criteria. Almost all existing graph
clustering approaches focus on either the similarity of topological
structure around vertices or the similarity of attribute values
associated with vertices.  In this talk, we discuss a new graph
clustering approach based on both structural and attribute
similarities using a unified distance measure.  Our approach
partitions a large attribute graph into k clusters such that each
cluster contains a densely connected subgraph with homogeneous
attribute values. We will discuss the details of our approach in this
talk.
