コースの説明

前提条件

1

Introduction to networks

In this chapter, you will be introduced to fundamental concepts in social network analysis. You will learn how to use the igraph R package to explore and analyze social network data as well as learning how to visualize networks.

What are social networks?

Creating an igraph object

Counting vertices and edges

Network attributes

Node attributes and subsetting

Edge attributes and subsetting

Visualizing attributes

Quiz on attributes

Network visualization

igraph network layouts

Visualizing edges

Quiz on igraph objects

2

Identifying important vertices in a network

In this chapter you will learn about directed networks. You will also learn how to identify key relationships between vertices in a network as well as how to use these relationships to identify important or influential vertices. Throughout this chapter you will use a network of measles transmission. The data come from the German city of Hagelloch in 1861. Each directed edge of the network indicates a child becoming infected with measles after coming into contact with an infected child.

Directed networks

Directed igraph objects

Identifying edges for each vertex

Relationships between vertices

Distances between vertices

Finding longest path between two vertices

Important and influential vertices

Identifying key vertices

Betweenness

Visualizing important nodes and edges

Important vertices quiz

3

Characterizing network structures

This module will show how to characterize global network structures and sub-structures. It will also introduce generating random network graphs.

Introduction

Forrest Gump network

Network density and average path length

Graph density quiz

Understanding network structures

Random graphs

Network randomizations

Randomization quiz

Network substructures

Triangles and transitivity

Transitivity randomizations

Visualize largest cliques

4

Identifying special relationships

This chapter will further explore the partitioning of networks into sub-networks and determining which vertices are more highly related to one another than others. You will also develop visualization methods by creating three-dimensional visualizations.

Close relationships: assortativity & reciprocity

Assortativity

Using randomizations to assess assortativity

Reciprocity

Assortativity quiz

Community detection

Fast-greedy community detection

Edge-betweenness community detection

Community quiz

Interactive network visualizations

Interactive networks with threejs

Sizing vertices in threejs

3D community network graph
