Another Look at Our Diplomatic Graph

I wrote yesterday about my network graph about U.S.-Barbary diplomatic relations. The graph I showed was color-coded by nationality. That code was hand-inputted by me, no computation or algorithm necessary. A perhaps more interesting, and enigmatic, color-coding is the result of running a modularity algorithm in Gephi. This algorithm creates sub-communities from the large network graph. I will not lie: I do not understand the math behind the result. But the communities created by the…

When the United States became independent after the American Revolution, it had to struggle to protect its seaborne commerce in the Atlantic and Mediterranean. Americans had to rely on the goodwill of France, Portugal, and other European powers because the United States lacked the naval power necessary to protect its own shipping. Historical Background¬† Americans had to negotiate with the Barbary states to secure the release of hostages, taken by Barbary corsairs, and to decide…

Spurred by our DH reading group at Northeastern, as well as my general tendency to jump into things before really knowing what I’m doing, I decided a few weeks ago to download Gephi and see what sort of rudimentary networks I could create. I’d been cataloging the service record of each of my Preble’s Boys officers, setting up the chart so that I could see concurrent service. I started out just looking to see whether…
