-Leonard Zelig, Zelig (Allen, 1983) We have presented a metric for measuring linguistic accommodation in a systematic manner, considering not only the context of an individual pair's communications, but the background models for both individuals.
the Zelig Quotient provides an objective, quantifiable measure of convergence and divergence in language use between individuals, as defined by the movement in an individual's typical linguistic style towards or away from the typical linguistic style of their conversational partner.
