Text Attribution Tool

Appen’s Text Attribution Tool (TAT) is a powerful investigative software tool for forensic authorship profiling, capable of revealing demographic and psychometric author traits from a text sample of unknown source.

The TAT automates the analysis of text for stylo-metric and related psychological identifiers in various forms of data (email, online chat, scanned documents, etc). The tool is used by cyber investigators, who are not experts in linguistics, to generate additional investigative information from text in order to identify individuals of interest.

The tool can give the investigator the probability of a match to other inputted text, from known and unknown authors. For example, email text from an unknown author can be attributed to a known author with a given degree of certainty. The analysis helps investigators identify the author’s sex, age, geographic origin, whether English is his or her first language and other basic psychological and personality traits. While currently the TAT operates in English and Arabic, its modular design allows other languages to be added.
