In computational linguistics, lexical density constitutes the estimated measure of content per functional (grammatical) and lexical units (lexemes) in total. Specifically, this is a coefficient of the word type to token ratio of a text. The main application of the lexical density coefficient is to be found in corpus linguistics.
Lexical density may be determined thus:
(Tp / Tn)x100 = Ld
Where:
Tp = the number of word types in the analysed text
Tn = the number of all tokens in the analysed text
Ld = the analysed text's lexical density
