On the uniqueness of writing styles
- Problems and tasks of stylometry


Stylomtery advocates that no two people can express their thoughts in writing in the same way, that originality of human beings manifests itself also in our linguistic preferences and habits. The choices we make with respect to employed vocabulary, construction of sentences, used punctuation marks, are so individual that not only writer characterisation and comparison is possible, but also sufficiently reliable authorship attribution. Stylometric characteristic features can be applied to confirm true authorship of disputed historical texts, to help in forensic investigations with identification of document forgery or plagiarism, for literary, social or gender studies.

Nowadays a text can take a multitude of forms, which poses one of the challenges in stylometric processing, while others include recognition of ghost writers, adopting a style, changes of style over time, collaborations of several authors. Contemporary stylometric analysis bases on observations drawn from the constantly growing corpus of texts available through the Internet, relies heavily on computers, exploits statistical calculations, and implements methods and techniques from artificial intelligence domain.

Starting with comments on fundamental stylometric notions, this keynote will discuss some of widely used practices for input data preparation and processing, evaluation of effectiveness and performance, and provide illustration of problems with selected case studies.
