In this hands on workshop, we will provide an introduction to LDA Topic Modeling using the InPhO Topic Explorer - a new corpus construction and modeling framework made specifically for digital humanists. It features cross-platform support for Windows, Mac, and Linux with a simple single-command installation process. We show how this framework has been used for research on the HathiTrust Digital Library, Darwin's Reading Notebooks, the Old Bailey Online, and the Stanford Encyclopedia of Philosophy. The Topic Explorer also has the capacity to import any arbitrary collection of PDFs, TEI, and plain-text files. We can show how the process of replicable workflows enables rapid experimentation in the humanities and can enrich exploration by moving from texts to topics and back again.
