JGAAP was designed by Patrick Juola of Duquesne University, JGAAP stands for Java Graphical Authorship Attribution Program. It is a free Java-based program for textual analysis, text categorization, and authorship attribution.
Advantages of JGAAP
- Provides extensive analytical customization such as Canonicizers (normalizes texts), Culling (what is removed from the data), Analytical Events (features such as n-grams, word length, etc.), and Analysis methods (Burrow’s Delta, Chi-Squared, etc).
- Can process multiple texts and perform many different kinds of analytics at once.
- Works easily with Java, no additional software or coding knowledge required.
- GUI provides prompts and guidance related to different statistical options such as culling, analysis methods, and frequency options.
Disadvantages of JGAAP
- Does not generate visualizations of data; only generates raw statistical scores.
- Though the User Guide is very comprehensive, it has not been updated since version 5.1 (2013)
Fun Fact: Juola and JGAAP are most well known from the discovery of J.K. Rowling as author of The Cuckoo's Calling.
