Social Network Analysis using Gephi

When I came across a course on Social Network Analysis I came across Gephi. This post is a very simple attempt to give a very simple introduction of Social Network Analysis.

What is Social Network Analysis?

According to Wiki in simple terms it is analysis of social networks. Rather I would say it helps to analyze any data network. The key things which would be analyzed are is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other attributes. For example the given figure visually represents relationship between people.

In the future posts we will see more on using Gephi for Data Visualization for Social Network Analysis. Please read through a very good introduction on this topic and various other articles by Martin Grandjean on the subject.

What is Gephi?

According to gephi.com “Gephi” is a Open source data visualization tool or all kinds of networks and complex systems, dynamic and hierarchical graphs.

Example:

Now we will have simple example of 8 friends how they are networked.

Nodes:

Here the nodes are the friends namely :

ID,Label

1,Siva

2,Kumar

3,Kannan

4,Vijay

5,GopiKrishna

6,Aditya

7,Ilango

8,Ramesh

Edges:

Each Id will have a relationship with another Id. Let’s see how they are linked based on how they have been closely related by introduction:

Source,Target

1,2

1,3

1,4

1,5

2,5

3,7

3,8

So to handle this with Gephi we can do it with the help of a CSV File, so we need two files which will be imported to Gephi. In my next post we will how do we do this step by step with Gephi.
