Social Network Analysis

Social network analysis, usually referred to as SNA, creates a model and studies the relationships of a group of social entities that exist in the form of a network. An entity can be a person, a computer, or a web page, and a relationship can be a like, link, or friendship (that is, a connection between entities).

In this chapter, you'll learn about the following:

  • Graphs, since social networks are usually represented in this form
  • Important algorithms that are used to gain insights from a graph
  • How to load, dump, and sample large graphs
