- Using Metadata to Find Paul Revere | Kieran Healy
- The data come from an appendix to David Hackett Fischer's Paul Revere's Ride (Oxford University Press, 1995)
- The Other Ride of Paul Revere: The Brokerage Role In The Making of The American Revolution | Shin-Kap Han
London, 1772.
I have been asked by my superiors to give a brief demonstration of the surprising effectiveness of even the simplest techniques of the new-fangled Social Networke Analysis in the pursuit of those who would seek to undermine the liberty enjoyed by His Majesty’s subjects. This is in connection with the discussion of the role of “metadata” in certain recent events and the assurances of various respectable parties that the government was merely “sifting through this so-called metadata” and that the “information acquired does not include the content of any communications”. I will show how we can use this “metadata” to find key persons involved in terrorist groups operating within the Colonies at the present time. I shall also endeavour to show how these methods work in what might be called a relational manner...

Functional Explanations
- Matrices are collections of elements into rows and columns.
- Matrix multiplication relies on Dot Product to multiply various combinations of rows and columns. A thing about multiplying matrices is that the order matters.
- Adjacency Matrix - is a 2D array of size V x V where V is the number of vertices in a graph. The matrix is often used in network analysis to represent the adjacency of each person to each other person in a network. An adjacency matrix is a square person-by-person matrix
- Eigenvector Centrality - a measure of the influence of a node in a network
- Knowledge Graphs are very useful ways of presenting information about social networks.
