Lexical Density

In computational linguistics, lexical density constitutes the estimated measure of content per functional (grammatical) and lexical units (lexemes) in total. It is used in discourse analysis as a descriptive parameter which varies with register and genre. Spoken texts tend to have a lower lexical density than written ones, for example.

Lexical density may be determined thus:

Ld = (Nlex / N)x100

Where:

Ld = the analysed text's lexical density

NLex = the number of lexical word tokens (nouns, adjectives, verbs, adverbs) in the analysed text

N = the number of all tokens (total number of words) in the analysed text
