The Croatian Language Corpus was built between 2007 and 2011 at the Institute of Croatian Language and Linguistics in the scope of the research programme "Hrvatska jezična riznica" as a reference corpus of Croatian language to serve various lexicographic and other linguistic and language technology projects. The corpus consists of 28% of fiction texts and 72% of specialized texts. In 2017, the corpus was segmented, part-of-speech tagged and lemmatized inside the MREŽNIK project to be used for the development of the first Croatian corpus-based dictionary.
