deTenTen: Corpus of the German Web
The German Web Corpus (deTenTen) is a corpus made up of texts collected from the internet. The corpus belongs to the TenTen corpus family which is a set of the web corpora built using the same method with a target size 10+ billion words. Sketch Engine currently provides access to TenTen corpora in more than 40 languages.
The newest German Web 2020 corpus consists of 17.5 billion words of texts collected from the web in June and July 2020. The Wikipedia part is from September to November 2020. The corpus contains lemmatization including gender lemmas and part-of-speech tagging. The sample texts of the biggest web domains which account for 50% of all corpus texts were checked semi-manually and content with poor quality text and spam was removed.
Detailed information about TenTen corpora is on the separate page Common TenTen corpora attributes.
Part-of-speech tagset
This German corpus was tagged by RFTagger using this POS tagset.
Genre annotation and topic classification
A part of the German Web 2020 corpus contains genre annotation and topic classification. These can be displayed as corpus structures in Concordance or in the Text type Analysis tool. Genres refer to writing styles and are divided into three groups (blog, discussion, legal, news) whereas topic classification is inspired by categories used by https://curlie.org/ (formerly dmoz.org) and includes the following topics: arts, business, games, health, home, recreation, reference, science, sport, society, and technology.
- genres cover 18.9% of the corpus, i.e. 3.97 billion tokens
- topic classification covers 22.9% of the corpus, i.e. 4.8 billion tokens
