Title: Classical retrieval and overlap measures such as Jaccard's coefficient, Salton's cosine measure and the Dice coefficient satisfy the requirements for rankings based upon a Lorenz curve.
Authors: EGGHE, Leo

Abstract: Classical information retrieval and overlap measures such as the Jaccard index, the Dice coefficient and Salton's cosine measure can be characterized by Lorenz curves. This result demonstrates the existence of a link between information retrieval and the information sciences on the one hand, and concentration and diversity theory, as used, e.g., in social economics and ecology on the other.
