| Challenge: | Hate and offensive speech on social media is a global problem that suffers the community especially, for an under-resourced language like Afaan Oromo. |
| Approach: | They develop a model to detect and classify Afaan Oromo hate speech on social media using different machine learning algorithms. |
| Outcome: | The proposed model outperforms existing models in gender, religion, race, and offensive speech on social media. |

| Challenge: | Low-resource languages are lagging behind current state-of-the-art (SOTA) developments in the field of NLP due to insufficient resources to train LLMs. |
| Approach: | They propose to use multilingual large language models for five Ethiopian languages and a benchmark dataset to evaluate their performance. |
| Outcome: | The proposed models outperform existing models in five Ethiopian languages and a benchmark dataset for various downstream NLP tasks. |
