TIGQA: An Expert-Annotated Question-Answering Dataset in Tigrinya (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing annotated datasets for NLP tasks in languages with limited resources are limited. |
| Approach: | They propose to use machine translation to convert existing Tigrinya dataset into a Tigrina dataset in SQuAD format. |
| Outcome: | The proposed dataset is an expert-annotated Tigrinya dataset with 2,685 question-answer pairs covering 122 diverse topics. |
MoVoC: Morphology-Aware Subword Construction for Ge’ez Script Languages (2025.findings-emnlp)
Copied to clipboard
| Challenge: | Subword-based tokenization methods fail to preserve morphological boundaries, a limitation especially pronounced in low-resource, morphology complex languages such as those written in the Ge‘ez script. |
| Approach: | They propose a tokenizer that integrates supervised morphological analysis into the subword vocabulary and propose morpheme-based tokenization with Byte Pair Encoding (BPE) tokens. |
| Outcome: | The proposed tokenizer preserves morphological integrity while maintaining lexical meaning. |
