Welcome!
Welcome to the course website for the text as data workshop in the Marketing Group at Adelaide Business School in March 2023.
This course introduces students to Natural Language Processing (NLP) tools to analyze text - with an emphasis on "doing" analysis using the R programming language.
We assume that attendees have no previous experience with NLP tools.
The workshop will be "hands-on", with a mix of live coding that you can follow along with, and some short exercises (time permitting).
See the Installation Guide and Course Material tabs for the learning materials.
