The course is taught by Ryan Cordell (https://ryancordell.org/) and Gregory Palermo (https://palermog.github.io/) and draws extensively from previous courses taught by Ryan Cordell and Jonathan D. Fitzgerald (https://jonathandfitzgerald.com/) at Northeastern University in Spring 2017 (https://s17hda.ryancordell.org/) and by Benjamin Schmidt in 2015 (https://benschmidt.org/HDA15/). Some course exercises are modeled on chapters in Julia Silge and David Robinson's book Text Mining in R: A Tidy Approach (https://www.tidytextmining.com/), as well as on Taylor Arnold and Lauren Tilton's Programming Historian tutorial, "Basic Text Processing in R" (https://programminghistorian.org/en/lessons/basic-text-processing-in-r). There are other necessary acknowledgements, which we have attempted to include in the pertinent exercises.
