An Empirical Investigation of Word Alignment Supervision for Zero-Shot Multilingual Neural Machine Translation

no code implementations EMNLP 2021 Alessandro Raganato, Raúl Vázquez, Mathias Creutz, Jörg Tiedemann

In this paper, we investigate the benefits of an explicit alignment to language labels in Transformer-based MNMT models in the zero-shot context, by jointly training one cross attention head with word alignment supervision to stress the focus on the target language label.

SemEval-2024 Shared Task 6: SHROOM, a Shared-task on Hallucinations and Related Observable Overgeneration Mistakes

no code implementations12 Mar 2024 Timothee Mickus, Elaine Zosa, Raúl Vázquez, Teemu Vahtola, Jörg Tiedemann, Vincent Segonne, Alessandro Raganato, Marianna Apidianaki

This paper presents the results of the SHROOM, a shared task focused on detecting hallucinations: outputs from natural language generation (NLG) systems that are fluent, yet inaccurate.

Wikipedia Entities as Rendezvous across Languages: Grounding Multilingual Language Models by Predicting Wikipedia Hyperlinks

no code implementations NAACL 2021 Iacer Calixto, Alessandro Raganato, Tommaso Pasini

Further adding extra languages lead to improvements in most tasks up to a certain point, but overall we found it non-trivial to scale improvements in model transferability by training on ever increasing amounts of Wikipedia languages.

Multilingual NMT with a language-independent attention bridge

1 code implementation WS 2019 Raúl Vázquez, Alessandro Raganato, Jörg Tiedemann, Mathias Creutz

In this paper, we propose a multilingual encoder-decoder architecture capable of obtaining multilingual sentence representations by means of incorporating an intermediate {\em attention bridge} that is shared across all languages.
