A Benchmark Dataset and Learning High-Level Semantic Embeddings of Multimedia for Cross-Media Retrieval

The selection of semantic concepts for modal construction and data collection remains an open research issue. It is highly demanding to choose good multimedia concepts with small semantic gaps to facilitate the work of cross-media system developers. However, very little work has been done in this area. This paper contributes a new, real-world web image dataset for cross-media retrieval called FB5K. The proposed FB5K dataset contains the following attributes: 1) 5130 images crawled from Facebook; 2) images that are categorized according to users’ feelings; 3) images independent of text and language rather than using feelings for search. Furthermore, we propose a novel approach through the use of Optical Character Recognition and explicit incorporation of high-level semantic information. We comprehensively compute the performance of four different subspace-learning methods and three modified versions of the Correspondence Auto Encoder, alongside numerous text features and similarity measurements comparing Wikipedia, Flickr30k, and FB5K. To check the characteristics of FB5K, we propose a semantic-based cross-media retrieval method. To accomplish cross-media retrieval, we introduced a new similarity measurement in the embedded space, which significantly improved system performance compared with the conventional Euclidean distance. Our experimental results demonstrated the efficiency of the proposed retrieval method on three different datasets to simplify and improve general image retrieval.
