Game of Thrones, Murder Network Analysis

Game of Thrones, Murder Network Analysis by George McIntire.

From the post:

Everybody’s favorite show about bloody power struggles and dragons, Game of Thrones, is back for its seventh season. And since we’re such big GoT fans here, we just had to do a project on analyzing data from the hit HBO show. You might not expect it, but the show is rife with data and has been the subject of various data projects from data scientists, who we all know love to combine their data powers with the hobbies and interests.

Milan Janosov of the Central European University devised a machine learning algorithm to predict the death of certain characters. A handy tool, for any fan tired of being surprised by the shock murders of the show. Dr. Allen Downey, author of the popular ThinkStats textbooks conducted a Bayesian analysis of the characters’ survival rate in the show. Data Scientist and biologist Shirin Glander applied social network analysis tools to analyze and visualize the family and house relationships of the characters.

The project we did is quite similar to that of Glander’s, we’ll be playing around with network analysis, but with data on the murderers and their victims. We constructed a giant network that maps out every murder of character’s with minor, recurring, and major roles.

The data comes courtesy of Ændrew Rininsland of The Financial Times, who’s done a great of collecting, cleaning, and formatting the data. For the purposes of this project, I had to do a whole lot of wrangling and cleaning of my own and in addition to my subjective decisions about which characters to include as well and what constitutes a murder. My finalized dataset produced a total of of 240 murders from 79 killers. For my network graph, the data produced a total of 225 nodes and 173 edges.

I prefer the Game of Thrones (GoT) books over the TV series. The text exercises a reader’s imagination in ways that aren’t matched by visual media.

That said, the TV series murder data set (Ændrew Rininsland of The Financial Times) is a great resource to demonstrate the power of network analysis.

After some searching, it appears that sometime in 2018 is the earliest date for the next volume in the GoT series. Sorry.
