Course primer

Start with Text as Data in Six Moves. It is the course’s short conceptual alternative to a dense textbook chapter.

The R foundations assignment lists the required Swirl lessons, DataCamp chapters, deadlines, and how completion is checked. Use the R foundations fallback if DataCamp access is not active. The course corpora guide explains what data we will use and when it is released. Approved teaching files are distributed through the separate private BA3 Text as Data corpora repository. The larger NLP Corpora for Korean Studies catalog remains an optional reference.

How tutorials are selected

Required Orange videos must be official and short. They must also work with the current interface. An older video may remain as an optional explanation when paired with current widget documentation. Required preparation should stay under 20 minutes per session. The full official YouTube channel is a tutorial library. Students are not expected to watch it in sequence.
