Lexical Diversity

InterCorp release 16ud is annotated by two measures of lexical diversity. They are specified as metadata for each text of sufficient length, for each linguistically annotated language. In KonText, they can be displayed and queried like any other metadata items, such as author or sentence ID.

• lexDivWord: average number of different word forms per 1000 tokens
• lexDivLemma: average number of different lemmas per 1000 tokens

The measures are based on the type-token ratio measure. They show the average number of different types (word forms or lemmas) in a moving window of 1000 tokens. If the text has less than 1000 tokens, the measures are not defined.
