What is British National Corpus?
The British National Corpus (BNC) is a 100-million-word collection of samples of a written and spoken language of British English from the later part of the 20th century.
The British National Corpus consists of the bigger written part (90 %, e.g. newspapers, academic books, letters, essays, etc.) and the smaller spoken part (remaining 10 %, e.g. informal conversations, radio shows, etc.). The spoken part is also available in the audio format, and it can be played directly in the Sketch Engine interface.
The corpus texts contain a large amount of information and thus each user can use many search criteria as a time of publication, region captured spoken text, type of media and text domain, or the David Lee’s classification – a detailed genre specification. The full list of genres of this classification is here.
