Forensic Linguistics

Authorship is the method used by a forensic linguist to determine who the author of a particular document is. Note that authorship is not handwriting analysis: it is only concerned with the actual language used. Authorship involves analysing documents of all types: letters, emails, mobile phone texts and any other electronically produced item of text. Dr Olsson has analysed thousands of documents for authorship, and has written reports in over 500 cases, both criminal and civil.
