Editor: Tidy Text Mining with R is the title of a book being written by Julia Silge and David Robinson. In it, the authors show how to use tidytext, an R package they co-developed, as a solution for text mining in R. It will be published by O’Reilly, but the draft copy is available free online right now. And a GitHub repo is also available. The following text is the draft introduction.
If you work in analytics or data science, like we do, you are familiar with the fact that data is being generated all the time at ever faster rates. (You may even be a little weary of people pontificating about this fact.) Analysts are often trained to handle tabular or rectangular data that is mostly numeric, but much of the data proliferating today is unstructured and typically text-heavy. Many of us who work in analytic fields are not trained in even simple interpretation of natural language.
We developed a new R package, tidytext (Silge and Robinson 2016), because we were familiar with many methods for data wrangling and visualization, but couldn’t easily apply these same methods to text. We found that using tidy data principles can make many text mining tasks easier, more effective, and consistent with tools already in wide use. By treating text as data frames of words, we can manipulate, summarize, and visualize the characteristics of text easily and integrate natural language processing into effective workflows we were already using.
The tools provided by the tidytext package are relatively simple; what is important is the possible applications. Thus, this book provides compelling examples of real text mining problems.
