text type

a text type is a generic name for values assigned to structures (e.g. documents, paragraphs, sentences and others) inside a corpus. Text types can refer to the source (newspaper, book etc.), medium (spoken, written), time (year, century) or any other type of information about text. Not all corpora have documents annotated for text types. Corpora can be divided into subcorpora based on text types and searches or word lists can be generated based on text types.
