A Client mobile application for Chinese-Spanish statistical machine translation
(2014)
Conference report
Open AccessThis show and tell paper describes a client mobile application for Chinese-Spanish machine translation. The system combines a standard server-based statistical machine translation (SMT) system, which requires online ... -
A Deep source-context feature for lexical selection in statistical machine translation
(Elsevier, 2016-05-01)
Article
Open AccessThis paper presents a methodology to address lexical disambiguation in a standard phrase-based statistical machine translation system. Similarity among source contexts is used to select appropriate translation units. The ... -
A differentiable BLEU loss. Analysis and first results
(2018)
Conference report
Open AccessIn natural language generation tasks, like neural machine translation and image captioning, there is usually a mismatch between the optimized loss and the de facto evaluation criterion, namely token-level maximum likelihood ... -
A MOOC on approaches to machine translation
(2015-12-10)
Article
Open AccessThis paper describes the design, development, and analysis of a MOOC entitled “Approaches to Machine Translation: Rule-based, statistical and hybrid”, and provides lessons learned and conclusions to be taken into account ... -
A neural approach to language variety translation
(Association for Computational Linguistics, 2018)
Conference lecture
Restricted access - publisher's policyIn this paper we present the first neural-based machine translation system trained to translate between standard national varieties of the same language. We take the pair Brazilian - European Portuguese as an example and ... -

An analysis of gender bias studies in natural language processing
(Springer Science and Business Media LLC, 2019-10-14)
Article
Open AccessArtificial intelligence systems copy and amplify existing societal biases, a problem that by now is widely acknowledged and studied. But is current research of gender bias in natural language processing actually moving ... -
An IR-based strategy for supporting Chinese-Portuguese translation services in off-line model
(2014-04-01)
Article
Restricted access - publisher's policyThis paper describes an Information Retrieval engine that is used to support our Chinese-Portuguese machine translation services when no internet connection is available. Our mobile translation app, which is deployed on ... -

Attention weights in transformer NMT fail aligning words between sequences but largely explain model predictions
(Association for Computational Linguistics, 2021)
Conference lecture
Open AccessThis work proposes an extensive analysis of the Transformer architecture in the Neural Machine Translation (NMT) setting. Focusing on the encoder-decoder attention mechanism, we prove that attention weights systematically ... -
Automatic and human evaluation study of a rule-based and a statistical Catalan-Spanish machine translation systems
(2011)
Conference report
Open AccessMachine translation systems can be classified into rule-based and corpus-based approaches, in terms of their core technology. Since both paradigms have largely been used during the last years, one of the aims in the ... -

Automatic normalization of short texts by combining statistical and rule-based techniques
(2013-03-01)
Article
Open AccessShort texts are typically composed of small number of words, most of which are abbreviations, typos and other kinds of noise. This makes the noise to signal ratio relatively high for this specific category of text. A high ... -
