Outline of Final Research Achievements

Exhaustive comparative analysis has been carried out on a wide range of data mining techniques to help develop a highly accurate style variation detector on texts of mixed authorship. The development of the analytical methods draws heavily on machine-learning approaches in an effort to identify subtle stylistic shifts or variations in texts. The stylometric authorship attribution methods studied in this research have achieved a high degree of accuracy, making it possible to pinpoint where one author takes over from the other in texts of mixed authorship.
