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.
