How robust are multilingual information retrieval systems?

Thomas Mandl, Christa Womser-Hacker, Giorgio Di Nunzio, Nicola Ferro
2008 Proceedings of the 2008 ACM symposium on Applied computing - SAC '08  
The results of information retrieval evaluations are often difficult to apply to practical challenges.  ...  Consequently, robustness is an important issue especially for cross-language retrieval system evaluation.  ...  In this paper, we analyze how the results of mono-and multilingual retrieval evaluation is affected by using mean average precision and a robust measure, in our case the geometric mean.  ...

The Cross-Lingual Arabic Information REtrieval (CLAIRE) System [article]

Zhizhong Chen, Carsten Eickhoff
2021 arXiv   pre-print
In this paper, we build our end-to-end Cross-Lingual Arabic Information REtrieval (CLAIRE) system based on the cross-lingual word embedding where searchers are assumed to have a passable passive understanding  ...  of Arabic and various supporting information in English is provided to aid retrieval experience.  ...  Also, how to transfer pre-trained translation models to the new dataset properly and how to incorporate it into the information retrieval system eectively still remain challenging open tasks.  ...

STATISTICAL SIGNIFICANCE IN MULTILINGUAL INFORMATION RETRIEVAL (MLIR) SYSTEM

Sadanandam Manchala
2012 IOSR Journal of Engineering  
The efficiency of retrieval system is precise by comparing performance on a regular set of queries in Information Retrieval (IR) and MLIR systems.  ...  Significance tests are often used to estimate the reliability of such comparisons. In this research paper, we revisit the question of how such significance tests should be used.  ...  Moreover, since the hypotheses underlying nonparametric tests are not always strictly respected in the multilingual information retrieval system, this system suggests to both analyse the performance of  ...

Upgrading the Newsroom: An Automated Image Selection System for News Articles [article]

Fangyu Liu, Rémi Lebret, Didier Orel, Philippe Sordet, Karl Aberer
2020 arXiv   pre-print
The system fuses multiple textual sources extracted from news articles and accepts multilingual inputs.  ...  The system is compared with multiple baselines with ablation studies and is shown to beat existing text-image retrieval methods in a weakly-supervised learning setting.  ...  In this paper, we present a novel system for multimodal multilingual bidirectional retrieval with image and text as modalities.  ...
