The KoKo Corpus is an error-annotated learner corpus in German that consists of texts collected in public schools and produced mainly by L1 German speakers. It has been created with the aim to investigate and describe the writing skills of German-speaking secondary-school pupils at the end of their school career by analysing authentic texts produced in classrooms during the KoKo project. The essays were collected in South Tyrol (Italy), Tyrol (Austria) and Thuringia (Germany).
The KoKo Corpus consists of 1503 argumentative essays which contain manually performed transcription annotations and linguistic error annotations.
