Spotlight on stylometric text analysis
Different authors have different writing styles. Like the lenght of words and sentence, the frequencies of word, the frequencies of word forms, the richness of vocabulary, the use of punctuation and on. The author can also have preferences for certain spelling variants or using certain expressions.
Stylometry is the study of measurable features of style.
The Story of the Phantom
The Story of the Phantom is a series of 15 novels, published by Avon Publications in the U.S. from 1972 to 1975, based on Lee Falk's Phantom stories.
|Basil Copper||2, 3||#2 The adaptor is not credited|
|Frank S. Shawn||4, 5, 7, 8, 10, 11||#10 The adaptor is not credited|
|Lee Falk||1, 6, 9, 12, 15||#15 is wrongly credited as Carson Bingham|
When released the adaptor of issues 2 and 10 was not credited, and issue 15 was credited as Carson Bingham. Lee Falk did correct this using an "Author's note"' in the books.
Stylometric analysis to see if Lee Falk's correction in the "Author's note" can been confirmed.
- JGAAP = Java Graphical Authorship Attribution Program
- MFW - most frequent words
- MFC - most frequent characters
- n-Grams - Sample for character 2-grams: The Phantom said = th,he,e , p,ph,ha,an,nt, etc. Sample for word 2-grams: Hello, the Phantom said = hello the,the phantom,phantom said, etc.
- Corpus - collection of text. Here the 15 novels, from chapter 1 to the end of the novel.
The novels were prepared adding the novels to each of the authors, leaving issues 2, 10 and 15 as unknown authors. Using character 4-grams with nearest neighbor driver with metric Cosine Distance, issues 2, 10 and 15 were compared to the known authors.
The result were that the most likly author for: #2 is Basil Cooper, #10 is Frank S Shawn and #15 is Lee Falk.
The novels were put into one corpus folder. Two analysis were done: first 100-1000 MFW 2-gram and the second 100-1000 MFC 4-grams. Both using the Boostrap Consensus Tree.
The result grouping the novels according to the table above, confirming Lee Falk's correction in the "Author's note".
Interesting the analysis grouping issues 13 and 14 with statistic similar style.
