Overview of the Authorship Verification Task at PAN 2022

Abstract

The authorship verification task at PAN 2022 follows the experimental setup of similar shared tasks in the recent past. However, it focuses on a different, and very challenging scenario: given two texts belonging to different discourse types, the task is to determine whether they are written by the same author. Based on a new corpus in English, we provide pairs of texts using four discourse types: essays, emails, text messages, and business memos. The differences in communicative purpose, intended audience, and the level of formality render the cross-discourse-type authorship verification task very hard. We received 7 submissions and evaluated them using the TIRA integrated research architecture, along with two baseline approaches. This paper reviews the submissions and presents a detailed discussion of the evaluation results.
