Footnotes: In the Wikipedia conversions the text of the footnotes appears where normally the footnote reference mark would appear. This goes back to the Wikitext source. Although in the corpus representation, these insertions are marked using I5-markup, this is not visible in the COSMAS II result view. Here the footnote insertions appear in mid-text, in some cases in mid-sentence. In these cases it is also possible that the sentence segmentation does not meet the expectations In future Wikipedia conversions, the footnotes will be separated.

Please note:
- The foreign language Wikipedia corpora are not part of the Mannheim German Reference Corpus DeReKo.
- Footnotes: In the Wikipedia conversions, the text of the footnotes appears in the running text, where normally the footnote reference mark would appear. This goes back to the Wikitext source. Although in the corpus representation, these insertions are marked up using I5 markup, this is not visible in the COSMAS II result view. Here the footnote insertions appear in mid-text, in some cases in mid-sentence. In these cases it is also possible that the sentence segmentation does not meet the expectations. In future Wikipedia conversions, footnotes will be separated.
- Tokenization: The foreign language Wikipedia corpora have been converted with the same conversion pipeline from the Wikipedia dumps as the German corpora. That means that a tokenization was used during the import in COSMAS II which had originally been developed for the German language. In particular, the apostrophe (`) is not regarded as a token separator in this tokenization. As a consequence, in the French and Italian WP, all the proclitic articles, pronouns and other function words separated by an apostrophe together with their base word are represented as one token (for example in French l'amour, c'est, n'est, m'ennuie). That means, if COSMAS II is searched for the word form amour, the cliticized form l'amour will not appear in the result list. As a remedy, wildcard operators be used (e.g. the search query *amour), or the cliticized forms can be explicitly enumerated in the query.
- Similarly, the lemmatization in COSMAS II works only for German. Hence it makes no sense to use the base form operator '&' in queries to the foreign langauge Wikipedias.
- Accordingly, a hyphen is not considered a token separator. Hence, in the French WP, all forms with a phonetically induced -t- insertion are represented as one token (a-t-il, a-t-on, va-t-on etc.).
