Syntax as a Rosetta Stone: Universal Dependencies for In-Context Coptic Translation (2026.findings-acl)
Copied to clipboard
| Challenge: | Existing work using bilingual dictionaries to support inference for vocabulary items is lacking for low-resource languages. |
| Approach: | They propose to use universal dependency parses of input sentences to augment in-context learning prompts for low resource machine translation for the Coptic language. |
| Outcome: | The proposed approach achieves state-of-the-art results for the Coptic language. |
Getting The Most Out of Your Training Data: Exploring Unsupervised Tasks for Morphological Inflection (2024.emnlp-main)
Copied to clipboard
| Challenge: | Pre-trained transformers have been shown to be effective in many natural language tasks, but are under-explored for character-level sequence to sequence tasks. |
| Approach: | They propose to use pre-trained transformers for character-level morphological inflection in several languages to train models for unsupervised tasks. |
| Outcome: | The proposed model outperforms the best two shared tasks on morphological inflection and graphemeto-phoneme conversion benchmarks. |
