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. |
