A research on evaluation of written productive vocabulary based on Sugeno measure

This paper provides a new method for written productive vocabulary evaluation, an algorithm based on Sugeno measure. Lexical Richness and Lexical Frequency Profile are selected as evaluation indexes, and weight parameters are given by experts. Then Sugeno measure is used to integrate them. The experimental results have shown that, compared with traditional evaluation method based on teachers´ subjective experience, this method is more feasible.
