Chen, Ye-Sho; Leimkuhler, Ferdinand F. – Journal of the American Society for Information Science, 1989
Establishes a type-token identity relating type-token ratio and bilogarithmic type-token ratio; uses the Simon-Yule model of Zipf's law to drive the type-token ratio and provide a statistical model of text generation; and refines the model to allow for decreasing entry rates of new words.
