Touché at CLEF 2026

Synopsis/Call

Decision-making and opinion-forming are everyday tasks that involve weighing pro and con arguments for or against different options. Our goal is to foster the development of technologies that support people in decision-making and opinion-forming and to improve our understanding of these processes. We invite you to participate in the 7th Touché lab on argumentation at CLEF 2026 featuring four tasks.

Paper Submission

Follow the instructions on the CLEF 2026 homepage to prepare and submit your paper.

  • Note that you can submit a paper without registering or attending the conference - there is no publication fee.
  • Take a look at papers from previous years for reference, but note that you do not need to (and maybe even can not) include results for the first submission of the paper - results are usually added only for the camera-ready version.
  • As the paper title, use the format <Your Team Name> at Touché: <Brief Description of your Approach>.
  • As the paper subtitle, use Touché at CLEF 2026 (as per the official template).
  • For citing Touché and the task you participated in, use \cite{kiesel:2026c,kiesel:2026d}; for citing TIRA, use \cite{froebe:2023}:
