Development and Maintenance of Contemporary Written Corpora

The world's largest collection of German-language corpora as an empirical basis for linguistic research

The Mannheim German Reference Corpus (DeReKo)

The Corpora of Contemporary Written German at the IDS

  • constitute the world's largest linguistically motivated collection (over 57.6 billion words as of January, 2024) of electronic corpora with written German texts from today and the recent past
  • can be accessed via COSMAS II and KorAP free of charge
  • contain belletristic, scientific and popular scientific texts, a large number of newspaper texts as well as a wide range of additional text types. They are being developed continuously
  • are being acquired aiming at maximizing size and diversity, allowing the creation of virtual corpora while using COSMAS II and KorAP. These can be either representative corpora or corpora designed for particular research question
