# Amharic Passage Retrieval Dataset with Negatives

This dataset is a version of [amharic-news-category-classification](https://huggingface.co/datasets/rasyosef/amharic-news-category-classification) that has been filtered, deduplicated, and formatted for passage retrieval.

This dataset can be used directly with Sentence Transformers to train Amharic Text embedding and Reranking models.

#### Hard Negatives:
The `negative_passages` column contains hard negative passages that were mined using the [roberta-amharic-text-embedding-medium](https://huggingface.co/rasyosef/roberta-amharic-text-embedding-medium) embedding model.

### Source Datasets:

- https://huggingface.co/datasets/rasyosef/amharic-news-category-classification

### Models and Code
The following Text Embedding and ColBERT late-interaction retrieval models were trained using this dataset as part of our **ACL 2025 Findings** paper: ***Optimized Text Embedding Models and Benchmarks for Amharic Passage Retrieval***.
