Lexical Frequency Profiles

Research output: Chapter in Book/Report/Conference proceedingEntry for encyclopedia/dictionarypeer-review


Abstract How do we know that people use rich and sophisticated vocabulary in their writing? Laufer and Nation (1995) proposed that the vocabulary richness of a text could be measured by a quantitative index called the lexical frequency profile (LFP) which uses the proportion of frequent versus nonfrequent vocabulary in the text.
