Late fusion of heterogeneous methods for multimedia image retrieval

Hugo Jair Escalante, Carlos A. Hérnadez, Luis Enrique Sucar, Manuel Montes
2008 Proceeding of the 1st ACM international conference on Multimedia information retrieval - MIR '08  
The latter reduces the diversity and complementariness of documents considered for the fusion, as a consequence the performance of the fusion approach is poor.  ...  Late fusion of independent retrieval methods is the simpler approach and a widely used one for combining visual and textual information for the search process.  ...  Therefore, alternative strategies for evaluating the goodness of IRMs for HLFIRM are needed.  ...

Exploiting Visual-based Intent Classification for Diverse Social Image Retrieval

Bo Wang, Martha A. Larson
2017 MediaEval Benchmarking Initiative for Multimedia Evaluation  
In the 2017 MediaEval Retrieving Diverse Social Images task, we (TUD-MMC team) propose a novel method, namely an intent-based approach, for social image search result diversification.  ...  Our results reveal that, compared to conventional diversification strategies, intent-based search result diversification is able to bring a considerable improvement in terms of cluster recall with several  ...  In contrast, less research has focused on social, affective and subjective properties of data, for example, why the image was taken.  ...

Multimedia information seeking through search and hyperlinking

Maria Eskevich, Tom de Nies, Pedro Debevere, Rik Van de Walle, Petra Galuscakova, Pavel Pecina, Martha Larson, Gareth J.F. Jones, Robin Aly, Roeland J.F. Ordelman, Shu Chen, Danish Nadeem (+3 others)
2013 Proceedings of the 3rd ACM conference on International conference on multimedia retrieval - ICMR '13  
Existing work on multimedia information retrieval has focused on search for individual relevant items or on content linking without specific attention to search results.  ...  The results of our experiments are used to propose a research agenda for developing effective techniques for search and hyperlinking of multimedia content.  ...  Our investigation of multimedia focuses on both spoken content retrieval and video search. A range of previous investigations have explored effectiveness of these tasks.  ...

In-depth Exploration of Geotagging Performance using Sampling Strategies on YFCC100M

Giorgos Kordopatis-Zilos, Symeon Papadopoulos, Yiannis Kompatsiaris
2016 Proceedings of the 2016 ACM Workshop on Multimedia COMMONS - MMCommons '16  
Evaluating multimedia analysis and retrieval systems is a highly challenging task, of which the outcomes can be highly volatile depending on the selected test collection.  ...  To alleviate this problem, we propose an evaluation methodology based on an array of sampling strategies over a reference test collection, and a way of quantifying and summarizing the volatility of performance  ...  The proposed framework is particularly designed for the problem of multimedia geotagging, but could be adapted for different multimedia analysis and retrieval problems.  ...
