Abstract: Technologies for argument mining and argumentation analysis are maturing rapidly, so that, as a result, the retrieval of arguments in search scenarios becomes a feasible objective. For the second time, we organize the Touché lab on argument retrieval with two shared tasks: (1) argument retrieval for controversial questions, where arguments are to be retrieved from a focused debate portal-based collection and, (2) argument retrieval for comparative questions, where argumentative documents are to be retrieved from a generic web crawl. In this paper, we briefly summarize the results of Touché 2020, the first edition of the lab, and describe the planned setup for the second edition at CLEF 2021.
