Krill: KorAP search and analysis engine

KorAP (Korpusanalyseplattform) is a corpus search and analysis platform for handling very large corpora with multiple annotation layers, multiple query languages, and complex licensing models (Bański et al., 2013a). It is intended to succeed the COSMAS II system (Bodmer, 1996) in providing DEREKO, the German reference corpus (Kupietz and Lüngen, 2014), hosted by the Institute for the German Language (IDS). The corpus consists of a wide range of texts such as fiction, newspaper articles and scripted speech, annotated on multiple linguistic levels, for instance part-of-speech and syntactic dependency structures. It was reported to contain approximately 30 billion words in September 2016 and still grows continually.
