Definition

A lexical density measure computed by sliding a fixed-size token window across a text, calculating the type–token ratio (unique types divided by tokens) within each window, and reporting the average (or time series) of those local ratios; designed to reduce sensitivity of plain TTR to overall text length and to highlight local variation in lexical diversity.
