Searching for Needles in a Haystack: On the Role of Incidental Bilingualism in PaLM's Translation Capability

no code implementations17 May 2023 Eleftheria Briakou, Colin Cherry, George Foster

We investigate the role of incidental bilingualism -- the unintentional consumption of bilingual signals, including translation examples -- in explaining the translation capabilities of large language models, taking the Pathways Language Model (PaLM) as a case study.

Can Synthetic Translations Improve Bitext Quality?

no code implementations ACL 2022 Eleftheria Briakou, Marine Carpuat

Synthetic translations have been used for a wide range of NLP tasks primarily as a means of data augmentation.

A Review of Human Evaluation for Style Transfer

1 code implementation ACL (GEM) 2021 Eleftheria Briakou, Sweta Agrawal, Ke Zhang, Joel Tetreault, Marine Carpuat

However, in style transfer papers, we find that protocols for human evaluations are often underspecified and not standardized, which hampers the reproducibility of research in this field and progress toward better human and automatic evaluation methods.

Ol\'a, Bonjour, Salve! XFORMAL: A Benchmark for Multilingual Formality Style Transfer

no code implementations NAACL 2021 Eleftheria Briakou, Di Lu, Ke Zhang, Joel Tetreault

We take the first step towards multilingual style transfer by creating and releasing XFORMAL, a benchmark of multiple formal reformulations of informal text in Brazilian Portuguese, French, and Italian.

Beyond Noise: Mitigating the Impact of Fine-grained Semantic Divergences on Neural Machine Translation

2 code implementations ACL 2021 Eleftheria Briakou, Marine Carpuat

While it has been shown that Neural Machine Translation (NMT) is highly sensitive to noisy parallel training samples, prior work treats all types of mismatches between source and target as noise.

Detecting Fine-Grained Cross-Lingual Semantic Divergences without Supervision by Learning to Rank

1 code implementation EMNLP 2020 Eleftheria Briakou, Marine Carpuat

Detecting fine-grained differences in content conveyed in different languages matters for cross-lingual NLP and multilingual corpora analysis, but it is a challenging machine learning problem since annotation is expensive and hard to scale.

Cross-topic distributional semantic representations via unsupervised mappings

no code implementations NAACL 2019 Eleftheria Briakou, Nikos Athanasiou, Alexandros Potamianos

In traditional Distributional Semantic Models (DSMs) the multiple senses of a polysemous word are conflated into a single vector space representation.
