Workshop «Learn to Visualise Twitter and Facebook Data Using Gephi»

By Natalia Mazzote

Gephi is an open-code programme that allows you to visualize and consult graphs. It can be used in sectors as varied as politics, health, social networks, etc. Media such as The New York Times use it to visualise the global connectivity of their contents and Twitter uses it to examine network traffic around determined events. The truth is that Gephi offers the possibility of managing thousands of nodes and of working while carrying out large-scale analysis. This workshop introduce us to Gephi as users, based on data from the two most widely-used social networks: Facebook and Twitter, while explaining basic graph theory concepts such as hubs, nodes and types of networks. To follow the workshop it is necessary to have Gephi installed on your computer. To download it please go to: http://gephi.github.io/users/download/
