Document frequency


For a type, the number of documents with at least one occurrence of this type; this measure is used in computational linguistics (cf. TF/IDF; Salton and McGill, 1983) as well as in the field of psycholinguistics (as contextual diversity; Adelman, Brown und Quesada, 2006).

For case-insensitive document frequency, please see Type DC document frequency in the Types DC table.
