Text mining practicum

In addition to my graduate course, I teach the the Text Mining Practicum at SMU. It is fifteen hours, divided into five sessions. It covers R, text mining, visualizations, and the basics of data science.

These videos are not exceptionally produced. It’s great if you want to watch me teach and then make fun of me!

As I was preparing these videos, I heard myself saying “um” a lot. Yikes! I’ll work on that in the future.

Session 1: R basics and Tidy Text Format

This session covers the basics of R and chapter 1 of Text Mining with R.
