Meaning of type-token ratio | Babel Free

Noun CEFR B2

Definitions

The ratio of the number of different words (types) occurring in a text or corpus to the overall number of words (tokens) in the same text or corpus.

Examples

“We identify vocabulary richness by using a well-established measure of textual, lexical diversity (MTLD) which is often used in the field of automated essay grading. It takes into account the number of unique words but unlike the best-known measure of lexical diversity, the type-token ratio (TTR), it is not as sensitive to the difference in the length of the texts.”
