Exercise

Calculate the betweenness scores

Betweenness centrality represents the degree to which nodes stand between each other.

In a retweet network, a user with a high betweenness centrality score would have more control over the network because more information will pass through the user.

Can you identify users who are central to people who retweet the most and those whose tweets are retweeted frequently?

The retweet network on #travel has been pre-loaded as nw_rtweet.

The library igraph has been pre-loaded for this exercise.
