Making informed decisions and forming opinions on a matter often involves not only weighing pro and con arguments towards different options, but also considering cause-effect relationships for one's actions. Our goal is to foster and support the development of technologies for argument and causal retrieval and analysis. We invite you to participate in the 4th Touché lab on argument and causal retrieval at CLEF 2023 featuring four tasks. Read about Touché tasks [Touché papers].
