In some cases it is sufficient to know merely the range of argumentative types used in order to grade student essays (Ong, Litman, and Brusilovsky 2014), to know what stance an essay takes toward a proposition in order to check that it provides appropriate evidence to back-up its stance (Persing and Ng 2015), or whether a claim is verifiable in order to flag these in online discussions (Park and Cardie 2014).
if the goal is to reconstruct enthymemes (Razuvayevskaya and Teufel 2017) (see also the discussion of Feng and Hirst [2011] in Section 8.2) or ask critical questions about support relations, we also need to extract the nature of the argumentation schemes being used.
