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 ROUSSEAU, Ronald |
Issue Date: | 2005 | 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. | Keywords: | information retrieval; overlap studies; presence-absence data; Jaccard coefficient; Salton's cosine measure; Dice coefficient; Lorenz curves; Gini index | Document URI: | http://hdl.handle.net/1942/815 | Category: | O | Type: | Preprint |
