# Dataset Summary

CIRAL is a collection for cross-lingual information retrieval research across four (4) African languages. The collection comprises English queries and query-passage relevance judgements for passages in the African languages.
This dataset repo contains only the queries and relevance judgements. The corpus collection can be found here [here](https://huggingface.co/datasets/CIRAL/ciral-corpus)


# Dataset Structure
1. To download the files: The queries can be found under `ciral-{lang}/topics` and are in `.tsv` formats with each line in the form:

   ```
    qid\tquery
   ```
   while the judgements are in the folder `ciral-{lang}/qrels`, with each file in the standard TREC format:

   ```
    qid Q0 docid relevance
   ```
2. To access the dataset via `datasets`:
   
   ```
   ciral_dataset = load_dataset("ciral/ciral", "hausa") #or swahili, somali, yoruba

   for data in ciral_dataset['dev']:  # or 'testA' or 'testB'
      query_id = data['query_id']
      query = data['query']
      pos_qrels = data['positive_passages']
      neg_qrels = data['negative_passages']

      # To load test set A's pool judgments
      pools_pos_qrels = data['pools_positive_passages']
      pools_neg_qrels = data['pools_negative_passages']

      for qrel in pos_qrels:
         docid = qrel['docid']
         text = qrel['text']
   ```
