Novelty and Diversity in Image Retrieval

Simone Santini

2018

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.
