This is the dataset for the shared task on Text Watermarking PAN@CLEF2026. Please consult the task's page for further details on the format, the dataset's creation, and links to baselines and utility code. Task In the Text Watermarking task, participants are given a text and must insert a watermark into it. After submitting the watermark system, including a watermark detection algorithm, through TIRA, the watermark system is run on the test dataset. The watermarked texts are then subjected to various attacks. The objective is to detect the watermark after the text has been attacked, thereby demonstrating its robustness against an attacker.
