A corpus is a large and structured set of texts created for linguistic research. Ideally, there are also meta data and annotations.

This page has the aim of listing all CMC corpora freely available for (linguistic) research with either texts from Switzerland or compiled by Swiss researchers.

For CMC corpora without a link to Switzerland, please check the CLARIN page on CMC corpora.
