Analyzing the Twitter Conversation and Interest Graphs by Marti Hearst.
From the post:
For assignment 3, students analyzed and compared a portion of the Twitter “conversation graph” and the “interest graph”. Conversations were found by looking for Twitter “@mentions” and interest graph by looking at the friend/follow graphs for a user (finding friends of friends, taking a k-core analysis, and closing the triangles). The attached document highlights many of the students’ work.
One of the most impressive graphs was made by Achal Soni. He used Java and the Twitter4J library to obtain 3000 tweets for 4 rappers (Drake, Kendrick Lamar, J Cole, and Big Sean). He extracted @mentions from these tweets, and created a graph recording edges were between the celebrities and who they were conversing with.
A clever choice of colors makes this network representation work very well.
