Abstract
Classical information retrieval and overlap measures such as the Jaccard index, the Dice coefficient and Saltons cosine measure can be characterized by Lorenz curves. This result demonstrates the existence of a formal 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.
