When we think of the term ‘social network’ we don’t think about that network expanding back into colonial periods. Social networking is widely used today to communicate with lost acquaintances, and stay updated on trends. In a less modern sense, this social networking scheme can be used to track correspondences and give a detailed analysis of which groups are in communication. In the article, the strength of the relationship between the groups can indicate whether the groups were allies or not. This is useful to track “terrorists” as seen in the article.

The use of the betweenness scores was very interesting because it showed who was in the midst of communications, with Paul Revere having the clear highest score. This article also described the use of eigenvectors to further analyze the matrices, which is a very useful tool when using large dataframes.

As SJ mentioned in their blog, It is cool how we can use data that was not collected by direct communication. Secondhand communication suddenly comes into play in a large way, which introduces a whole new world of data collection.
