How to cite corpora accessed through the CNC

Display of information about the corpus including the citation sources in the KonText interface

Ways of citing the corpora

There are essentially two ways in which corpora can be cited in an academic text:

  1. listing the corpus as a reference or source of data;
  2. listing a reference to the specific article which describes the creation and the structure of the corpus.

It is for the user to decide between these two options, depending also on the specific purpose of the citation; it is, of course, possible to combine the two ways of citing. The specific form of the citation can be found on these wiki pages, on the page dedicated to the given corpus, and also in the KonText interface itself, after clicking on the link containing the name of the corpus.

Citations ad 1) are included without exception, citations ad 2) only in KonText and only for most of the corpora; they are missing in cases where no article with a description of the corpus could be found. In addition to specific bibliographic data, for some of the corpora in KonTextu you can find a direct link to the address from which the article can be downloaded.

Citing non-reference corpora

When citing versioned corpora, it is necessary to also include the version number. The version number is available in the KonText interface as part of the citation information.

When citing a specific text it is also possible to cite the list of sources SYN2000, SYN2005 or SYN2010.

Lemmatization and tagging

If you use lemmatization or morphological tags (attributes lemma or tag in the SYN series corpora), please also cite the following publications:
