Title: Tidy Text Mining with R
Abstract: Text data is increasingly important in many domains, but it can be challenging to manipulate and visualize within typical R analysis workflows. In this talk, I will introduce the tidytext package and show how tidy data principles and tools can make text mining easier and more effective, by structuring text as one-token-per-row. You'll learn how to manipulate, summarize, and visualize text's characteristics using R packages from the tidy ecosystem such as dplyr, ggplot2, and tidyr. You'll see case studies of sentiment analysis, tf-idf, and topic modeling applied to examples from literature, Twitter, and Stack Overflow questions, and gain the tools to draw conclusions from your own text datasets.
