Abstract: This paper studies the formalization and the use of the concepts of novelty and diversity to diversify the result set of a multimedia query, avoiding the presence of uninformative results. First, we review and adapt several diversity measures proposed in the information retrieval literature. The problem of maximizing diversity being NP-complete, we propose a general greedy algorithm (dependent on a scoring function) for finding an approximate solution, and instantiate it using three scenarios: a probabilistic one, a fuzzy one, and a geometric one. Finally, we perform tests on two data sets, one in which retrieval is based on annotations and the other in which retrieval is purely visual.
