Topic- and Structured Topic Modeling

You can try it:

Contents

These notebooks provide an introduction to Natural Language Processing (NLP) in R with an emphasis on Topic Modeling. The notebooks touche on issues ranging from data pre-processing and import to model inference and visualization. Readers will get a first insight into the practical aspects of text mining and relevant R packages for Quantitative Analysis of Textual Data and Structural Topic Modeling. The notebooks are intended as an extension of the talk “Introduction to topic modeling research” by Cornelius Puschmann at the BIGSSS Summer Schools in Computational Social Science in Bremen. The Jupyter version of the notebook presented by Cornelius Puschmann is included.
