====== 1.1 Sub-corpora ======
Based on the annotation of the languages per chat, different sub-corpora were created.  

The following basic considerations were applied when creating the sub-corpora:

===== Definitions for sub-corpora =====

  * Each chat was to be assigned to only one language-sub-corpus. 
  * Additionally, we differentiate between chats where we have demographic information for all participants and those where we do not. In the former case, the sub-corpus gets the extension _DEMOG.
  * Where additional tasks were performed on individual chats (e.g. normalization or part-of-speech tagging) we created additional sub-corpora per language.


===== Main sub-corpora =====

  * WUS: All data, i.e. the whole corpus
  * WUS_DEU: All data where non-dialectal German provides the most messages
  * WUS_DEU_DEMOG: A subgroup thereof where we have demographic information from all communication partners.
  * WUS_FRA: All data where French provides the most messages
  * WUS_FRA_DEMOG: A subgroup thereof where we have demographic information from all communication partners.
  * WUS_GSW: All data where dialectal German provides the most messages
  * WUS_GSW_DEMOG: A subgroup thereof where we have demographic information from all communication partners.
  * WUS_ITA: All data where Italian provides the most messages
  * WUS_ITA_DEMOG: A subgroup thereof where we have demographic information from all communication partners.
  * WUS_ROH: All data where Romansh provides the most messages
  * WUS_ROH_DEMOG: A subgroup thereof where we have demographic information from all communication partners.

Additionally to these corpora, you also see corpora with lowercase letters in the browser (e.g. deu-rftagged, ita-tagged, roh etc.). These corpora contain data from our [[https://wiki.linguistik.uzh.ch/sms4science|SMS project]].
===== Smaller corpora =====

Next to these main sub-corpora, there are some smaller sub-corpora:
  * WUS_SMALL: Chats that are either smaller than 100 messages or where the majority of messages are not in a national language.
  * WUS_SMALL_DEMOG: A subgroup thereof where we have demographic information from all communication partners.
  * WUSdemographics: Only demographic data per person. This sub-corpus is much faster if you want to look up demographic data only.
  * WUS_ARGDROP and WUS_ARGDROP_language: Sub-corpora for which argument drop has been manually annotated. For the architecture of the annotations and scientific considerations behind it see [[http://www.unige.ch/lettres/linge/syntaxe/journal/Volume11/11_Stuntebeck_2018.pdf|Stuntebeck, Franziska (2018): "Annotating Argument Drop in the Swiss WhatsApp Corpus".
