COWS-L2H: A corpus of Spanish learner writing

This paper presents the Corpus of Written Spanish of L2 and Heritage Speakers (COWS-L2H), a large corpus of compositions written by North American university students learning Spanish. The goals of this work are to (1) build a large corpus of Spanish learner writing that provides samples of written data from Spanish learners in the context of a North American university, (2) to contribute corpus data collected not only from second language (L2) learners of Spanish but also from learners of Spanish as a heritage language (SHL), and (3) to develop one of the few Spanish learner corpora to provide longitudinal data.
