 +When compiling the corpus, the primary goal was for it to be as diverse and representative as possible, reflecting the variability of Czech in all of its modes and ranges of use (written, spoken, online communication) and featuring rich annotation (the texts were [[en:pojmy:lemma|lemmatized]], [[en:pojmy:tag|morphologically tagged]] using two different systems, and furthermore they were annotated for phrasemes and so-called [[http://ufal.mff.cuni.cz/nametag|named entities]]). As far as writtenness and spokenness are concerned, the Koditex is a mixed corpus.
 +
 +The name //Koditex// is both an acronym of the Czech version of the phrase //**co**rpus of **di**versified **tex**ts// and a tribute to Vilém Kodýtek, author of a pioneering attempt to apply MDA to Czech based on the work of D. Biber.

-Unlike other CNCsynchronic corpora (e.g. [[en:cnk:syn2015|SYN2015]]), the Koditex is not made up of entire texts, but rather samples from the original texts, which are marked as <chunk> within the structure.+Unlike CNC's other synchronic corpora (e.g. [[en:cnk:syn2015|SYN2015]]), the Koditex is not made up of entire texts, but rather samples from the original texts, which are marked as ''<chunk>'' within the structure.
  
 Before sampling the assembled data for material to include in the final corpus, we decided to split texts longer than 5,000 words into contiguous chunks of 2,000–5,000 words (while respecting sentence boundaries). This decision was driven by several perceived advantages, primarily that of ensuring a higher overall diversity of the corpus in terms of registers as well as genres / text types. Before sampling the assembled data for material to include in the final corpus, we decided to split texts longer than 5,000 words into contiguous chunks of 2,000–5,000 words (while respecting sentence boundaries).

 The majority of texts (accounting for 76% of tokens) included in the corpus are Czech originals (not translations from other languages). The only exceptions are text classes where translated material is common in Czech in general, listed in the table below (the rest of the classes are 100% Czech originals). The majority of texts (accounting for 76% of tokens) included in the corpus are Czech originals (not translations from other languages).

-The vast majority of the material in the Koditex corpus draws on the resources of the Czech National Corpus (CNC); types of language data which are not collected by the CNC were acquired from other research centers. We would also like to thank Karel Pala and Vít Baisa from the [[https://nlp.fi.muni.cz/en/NLPCentre|NLPC at Masaryk University]], and Josef Šlerka and his team at Socialinsider, for providing raw data for the //wik// class and //mul// division, respectively.+The vast majority of the material in the Koditex corpus draws on the resources of the Czech National Corpus (CNC); types of language data which are not collected by the CNC were acquired from other research centers.
