In collaboration with the Leibniz Institute for the German Language (IDS) in Mannheim, ZAS has published the second release of the ZAS database for clause embedding predicates. In addition to several improvements and the elimination of minor errors in the annotation of the data, the database now has been updated to include the embedding type of direct speech (dSpeech). The database is being continuously expanded. The number of corpus entries now comprises almost 19,000 example sentences.
Here you can find the website of the database.
