Overview of Touché 2023: Argument and Causal Retrieval - Extended Abstract.

The goal of Touche is to foster and support the development of technologies for argument and causal retrieval and analysis. For the fourth time, we organize the Touche lab featuring four shared tasks: (a) argument retrieval for controversial topics, where participants retrieve web documents that contain high-quality argumentation and detect the argument stance, (b) causal retrieval, where participants retrieve documents that contain causal statements from a generic web crawl and detect the causal stance, (c) image retrieval for arguments, where participants retrieve images showing support or opposition to some stance from a focused web crawl, and (d) intra-multilingual multi-target stance classification, where participants detect the stance of comments on proposals from the multilingual participatory democracy platform CoFE. In this paper, we briefly summarize the results of Touche 2022 and describe the planned setup for the fourth lab edition at CLEF 2023.
