Oskar Enghoff - How to do Topic Modelling using R

29-01-2020

Oskar is a 3rd year PhD student doing his thesis on the communal and commercial manifestations of illicit drugs culture on the internet. Oskar will provide a basic overview of how to use R to do 'topic modelling', focusing on applications within social science research. Topic modelling is a machine learning approach to thematic coding of text data, where 'topics' (or themes) are automatically and inductively extracted from multiple documents which in turn are coded using these topics.
