Lektor: Slovenian Learner corpus of proofreading and translations

Corpus Lektor is an error-annotated Slovenian corpus of the author’s corrections of texts and translations. The aim of the corpus is to obtain an insight into the most common linguistic errors in Slovenian and the proofreading process. The texts were manually tagged and classified. The corpus contains a rich list of metadata such as types of corrections, information about the proofreader (gender, age, education – linguistics/non-linguistics, Slovenian/non-Slovenian), and information about the origin – whether it is a translation or an author’s text.
