Quality Beyond A Glance: Revealing Large Quality Differences Between Web-Crawled Parallel Corpora

COLING 2025main

Parallel corpora play a vital role in advanced multilingual natural language processing tasks, notably in machine translation (MT). The recent emergence of numerous large parallel corpora, often extracted from multilingual documents on the Internet, has expanded the available resources. Nevertheless…

Do Language Models Care about Text Quality? Evaluating Web-Crawled Corpora across 11 Languages

COLING 2024main

Large, curated, web-crawled corpora play a vital role in training language models (LMs). They form the lion’s share of the training data in virtually all recent LMs, such as the well-known GPT, LLaMA and XLM-RoBERTa models. However, despite this importance, relatively little attention has been given…

Cross-lingual neural fuzzy matching for exploiting target-language monolingual corpora in computer-aided translation

EMNLP 2022main

Computer-aided translation (CAT) tools based on translation memories (MT) play a prominent role in the translation workflow of professional translators. However, the reduced availability of in-domain TMs, as compared to in-domain monolingual corpora, limits its adoption for a number of translation t…

Rethinking Data Augmentation for Low-Resource Neural Machine Translation: A Multi-Task Learning Approach

EMNLP 2021main

In the context of neural machine translation, data augmentation (DA) techniques may be used for generating additional training samples when the available parallel data are scarce. Many DA approaches aim at expanding the support of the empirical data distribution by generating new sentence pairs that…
