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.
