The KUUS corpus comprises 17 textbooks and 7 workbooks (over 700,000 words) for Slovenian as a second and foreign language. Published between 2002 and 2023 at the Centre for Slovene as a Second and Foreign Language (Faculty of Arts, University of Ljubljana), these textbooks were widely used in the teaching of Slovenian as a second and foreign language to children, adolescents and adults in Slovenia and abroad at the time of the creation of the corpus. The metadata for each text includes its title, subtitle, authors, year of publication, publisher, CEFR level, target group and, for the textbooks, the number of estimated hours of the lessons.

The corpus is linguistically annotated with the CLASSLA pipeline (https://github.com/clarinsi/classla/) at the levels of tokenization, sentence segmentation, lemmatization, MULTEXT-East v6 MSD-tags (https://nl.ijs.si/ME/V6/msd/html/msd-sl.html), JOS dependency syntax (https://nl.ijs.si/jos/bib/jos-skladnja-navodila.pdf), and named entities (https://nl.ijs.si/janes/wp-content/uploads/2017/09/SlovenianNER-eng-v1.1.pdf).

As opposed to the previous 1.0 version of the corpus, the 2.0 version has been enlarged by 7 workbooks from sets whose textbooks were already part of KUUS 1.0. It is available not only in CoNLL-U format but also in TEI XML, and in vertical encoding.

The corpus KUUS 1.0 is presented in more detail in: KLEMEN, Matej, ARHAR HOLDT, Špela, POLLAK, Senja, KOSEM, Iztok, HUBER, Damjan, LUTAR, Mateja, 2022: Korpus učbenikov za učenje slovenščine kot drugega in tujega jezika.
