Authorship is a behavioural aspect of an author. Their sentential structure is distinctive and can be used to identify authors. Natural language processing (NLP) and semantic methods can be used to detect attribution. Authorship attribution (AA) has gained interest in various fields, including technology, education, and criminal forensics, because it is, in a way, a digital fingerprint that can be detected statistically. AA plays a vital role in information extraction and question answering systems. It is a non-topic classification problem.
