One of the biggest challenges hindering progress in low-resource and multilingual machine translation is the lack of good evaluation benchmarks. Current evaluation benchmarks either lack good coverage of low-resource languages, consider only restricted domains, or are low quality because they are constructed using semi-automatic procedures. In this work, we introduce the FLORES-101 evaluation benchmark, consisting of 3001 sentences extracted from English Wikipedia and covering a variety of different topics and domains. These sentences have been translated in 101 languages by professional translators through a carefully controlled process. The resulting dataset enables better assessment of model quality on the long tail of low-resource languages, including the evaluation of many-to-many multilingual translation systems, as all translations are multilingually aligned. By publicly releasing such a high-quality and high-coverage dataset, we hope to foster progress in the machine translation community and beyond.

  1. ARC-Encoder: learning compressed text representations for large language models

    cs.CL 2025-10 conditional novelty 6.0 of 10

    ARC-Encoder pools queries in an encoder's last attention layer to produce compressed continuous representations that a frozen decoder consumes as token embeddings.

  2. Building a Functional Machine Translation Corpus for Kpelle

    cs.CL 2025-05 conditional novelty 6.0 of 10

    The paper introduces the first claimed public English-Kpelle parallel corpus and shows that fine-tuning NLLB on it yields BLEU up to 30 for Kpelle-to-English.

  3. An Empirical Study of Many-to-Many Summarization with Large Language Models

    cs.CL 2025-05 conditional novelty 6.0 of 10

    Instruction-tuned open LLMs beat zero-shot GPT-4 on automatic many-to-many summarization scores without lowering MMLU, but human evaluation shows instruction tuning can increase factual errors.

  4. Faster Machine Translation Ensembling with Reinforcement Learning and Competitive Correction

    cs.CL 2025-01 conditional novelty 6.0 of 10

    A DQN-based candidate selection and a competitive correction block improve MT ensembling quality while reducing inference cost on English-Hindi and Hindi-English tasks.
