Properties

avgChunkSize: number

Mean content length in characters

informationDensity: number

Mean ratio of unique tokens to total tokens per chunk. Tokenised by whitespace+punctuation split. Range 0–1; lower may indicate repetitive content.

semanticCoherence: number

Fraction of chunks that end with a sentence-terminating character (., !, ?, or \n). Range 0–1; higher is better.

stdDevChunkSize: number

Population standard deviation of content length
