| Approach: | They propose a professionally translated extension of the TruthfulQA benchmark . it evaluates truthfulness in Basque, Catalan, Galician, and Spanish . |
| Outcome: | The proposed extension of the TruthfulQA benchmark evaluates truthfulness in Basque, Catalan, Galician, and Spanish. |

| Challenge: | AfroCS-xs is a low-quality dataset for code-switching in multilingual communities . code-witching is prevalent in multicultural societies but lacks high-quality data for model development . |
| Approach: | They propose to use human-validated synthetic code-switched datasets to generate code-witched sentences for four African languages and English within a specific domain—agriculture. |
| Outcome: | The proposed model improves translation accuracy on the high-quality dataset for four African languages and English within a specific domain—agriculture. |
Translating Domain-Specific Terminology in Typologically-Diverse Languages: A Study in Tax and Financial Education (2025.emnlp-main)
Copied to clipboard
| Challenge: | Existing public terminology datasets for MT research are limited in language coverage or domain specificity, making it difficult to assess or improve MT systems in specialized settings. |
| Approach: | They propose a multilingual terminology resource for tax and financial education covering seven typologically diverse languages: English, Spanish, Russian, Vietnamese, Korean, Chinese (traditional and simplified) and Haitian Creole. |
| Outcome: | The proposed terminology resource covers seven typologically diverse languages: English, Spanish, Russian, Vietnamese, Korean, Chinese (traditional and simplified) and Haitian Creole. |

| Challenge: | Existing ensemble approaches to large language models lack flexibility for mid-generation adaptation. |
| Approach: | They propose an adaptive ensemble decoding framework that dynamically selects semantically appropriate fusion units during generation. |
| Outcome: | The proposed framework outperforms existing ensemble frameworks on open-domain QA, arithmetic reasoning, and machine translation tasks. |
