摘要：

Many real applications naturally use graph to model the relationships of entities, including social networks, World Wide Web, collaboration networks, and biology. Many fundamental research problems have been extensively studied due to the proliferation of graph applications. Among them, cohesive subgraph computation, which identifies a group of highly connected vertices, has received great attention from research communities and commercial organizations. A cohesive subgraph is key to graph structure analysis and a variety of cohesive subgraph models have been proposed. In this talk, I will introduce popular models for cohesive subgraphs and discuss their applications. I will also cover a few recent works of mine in cohesive subgraph computation.
