Computational text analysis can be done in virtually any field, from biology to literature. You may use topic modeling to determine which areas are the most heavily researched in your field, or attempt to determine the author of an orphan work. Where can you find text to analyze? So many places! Read on for sources to find unique text content.
Genius – the song lyrics database
Genius started as Rap Genius, a site where rap fans could gather to annotate and analyze rap lyrics. It expanded to include other genres in 2014, and now manages a massive database covering Ariana Grande to Fleetwood Mac, and includes both lyrics and fan-submitted annotations. All of this text can be downloaded and analyzed using the Genius API. Using Genius and a text mining method, you could see how themes present in popular music changed over recent years, or understand a particular artist’s creative process.
Case.law – the case law database
The Caselaw Access Project (CAP) is a fairly recent project that is still ongoing, and publishes machine-readable text digitized from over 40,000 bound volumes of case law from the Harvard Law School Library. The earliest case is from 1658, with the most recent cases from June 2018. An API and bulk data downloads make it easy to get this text data. What can you do with huge amounts of case law? Well, for starters, you can generate a unique case law limerick:
Wheeler, and Martin McCoy.
Plaintiff moved to Illinois.
A drug represents.
Rocky was just the decoy.

Newspapers and More
There are many places you can get text from digitized newspapers, both recent and historical. Some newspaper are hundreds of years old, so there can be problems with the OCR (Optical Character Recognition) that will make it difficult to get accurate results from your text analysis. Making newspaper text machine readable requires special attention, since they are printed on thin paper and have possibly been stacked up in a dusty closet for 60 years! See OCR considerations here, but the newspaper text described here is already machine-readable and ready for text mining. However, with any text mining project, you must pay close attention to the quality of your text.
The Chronicling America project sponsored by the Library of Congress contains digital copies of newspapers with machine-readable text from all over the United States and its territories, from 1690 to today. Using newspaper text data, you can analyze how topics discussed in newspapers change over time, among other things.
Looking for newspapers from a different region? The library has contracts with several vendors to conduct text mining, including Gale and ProQuest. Both provide newspaper text suitable for text mining, from The Daily Mail of London (Gale), to the Chinese Newspapers Collection (ProQuest). The way you access the text data itself will differ between the two vendors, and the library will certainly help you navigate the collections. See the Finding Text Data library guide for more information.
The sources mentioned above are just highlights of our text data collection! The Illinois community has access to a huge amount of text, including newspapers and primary sources, but also research articles and books! Check out the Finding Text Data library guide for a more complete list of sources.
