| Challenge: | (2020) African languages are underrepresented in existing natural language processing datasets, research, and tools due to lack of datasets and reproducible results. |
| Approach: | They propose to create a dataset for named entity recognition (NER) in ten African languages. |
| Outcome: | The results of the first large dataset for named entity recognition (NER) in ten African languages are released to inform future research on African NLP. |

| Challenge: | Lower-resource corpora have systematic issues, including mislabeled or nonstandard/ambiguous language codes. |
| Approach: | They manually audit the quality of 205 language-specific corpora released with five major public datasets. |
| Outcome: | The results show that lower-resource corpora have systematic issues even for non-proficient speakers. |

| Challenge: | 'Low-resourced'-ness is a complex problem that goes beyond data availability and reflects systemic problems in society. |
| Approach: | They propose to use machine translation to scale to low-resourced languages by using a dataset and a benchmarking system to measure their resource use. |
| Outcome: | The proposed approach allows participants without formal training to make a unique scientific contribution. |

| Challenge: | Existing web crawls have demonstrated quality issues for low-resource languages . Existing pretraining corpora have numerous quality issues . |
| Approach: | They propose to audit existing pretraining corpora to understand and rectify quality issues . they pretrain a new T5-based model and evaluate its performance on multiple tasks . |
| Outcome: | The proposed model outperforms existing pretrained models on four NLP tasks. |

| Challenge: | Our Dataset is the first cross-lingual QA dataset with a focus on African languages. |
| Approach: | They propose to use African languages as the only high-coverage source of answer content for cross-lingual open-retrieval question answering systems. |
| Outcome: | Our Dataset includes 12,000+ XOR QA examples across 10 African languages. |
Zero-Shot Cross-Lingual Reranking with Large Language Models for Low-Resource Languages (2024.acl-short)
Copied to clipboard
| Challenge: | Large language models (LLMs) have shown impressive zero-shot capabilities in various passage ranking tasks. |
| Approach: | They analyze and compare the effectiveness of monolingual reranking using query or document translations and evaluate the effectiveness when leveraging their own generated translations. |
| Outcome: | The proposed models perform better when using their own translations than when using query or document translations. |
