This document discusses enabling a computational turn in the history of ideas by using digital tools and methods. It provides an example case study of creating a computational history of ideas through topic modeling of digitized texts. The methodology proposes building some interpretation into the computational tools from the start while making those interpretations explicit, and balancing existing knowledge with discovery. Challenges include addressing criticisms of the discipline of history of ideas. The goal is developing a sound methodology for computational analysis to have broader impact through smart digital infrastructure.
