Multimedia Information Retrieval based on Late Semantic Fusion Approaches: Experiments on a Wikipedia Image Collection

Multimedia Information Retrieval based on Late Semantic Fusion Approaches: Experiments on a Wikipedia Image Collection - scientific work related to Wikipedia quality published in 2013, written by Xaro Benavent, Ana García-Serrano, Ruben Granados, Joan Benavent and Esther de Ves.

Overview

Main goal of this work is to show the improvement of using a textual pre-filtering combined with an image re-ranking in a Multimedia Information Retrieval task. The defined three step-based retrieval processes and a well-selected combination of visual and textual techniques help the developed Multimedia Information Retrieval System to overcome the semantic gap in a given query. In the paper, five different late semantic fusion approaches are discussed and experimented in a realistic scenario for multimedia retrieval like the one provided by the publicly available ImageCLEF Wikipedia Collection.
