Learner corpora are traditionally defined as ‘systematic collections of authentic, continuous and contextualized language use (spoken or written) by L2 learners stored in electronic format’ (Callies & Paquot 2015). With this characterization, it appears very clearly that learner corpus researchers have always been interested in exploring the output of the more open-ended types of contextualized production tasks assigned to L2 learners (e.g. Granger 2008; Tracy-Ventura & Myles 2015). The term ‘learners’ here refers to Foreign and/or Second Language learners rather than to learners acquiring their native language (L1)
