PAN 2025: Shared Tasks on Authorship Analysis, Computational Ethics, and Originality
Call for Participation

We'd like to invite you to participate in the following shared tasks at PAN 2025 held in conjunction with the CLEF conference in Madrid, Spain.

1. Voight-Kampff Generative AI Detection.
Subtask 1: Given a (potentially obfuscated) text, decide whether it was written by a human or an AI.
Subtask 2: Given a document collaboratively authored by human and AI, classify the extent to which the model assisted.

2. Multilingual Text Detoxification.
Given a toxic piece of text, re-write it in a non-toxic way while saving the main content as much as possible.

3. Multi-Author Writing Style Analysis.
Given a document, determine at which positions the author changes.
