Structure of Networks? Network is a collection of objects where some pairs of objects are connected by links What is the structure of the network? 2/24/2019 Jure Leskovec, Stanford CS224W: Social and Information Network Analysis, http://cs224w.stanford.edu

Connectivity of Directed Graphs Strongly connected directed graph has a path from each node to every other node and vice versa (e.g., A-B path and B-A path) Weakly connected directed graph is connected if we disregard the edge directions E F B A Graph on the left is not strongly connected. D C G
