Datasets are taken from Facebook's [CRAG: Comprehensive RAG Benchmark](https://github.com/facebookresearch/CRAG), see their [arXiv paper](https://arxiv.org/abs/2406.04744) for details about the dataset construction.
CRAG (Comprehensive RAG Benchmark) is a rich and comprehensive factual question answering benchmark designed to advance research in RAG. The public version of the dataset includes:
- 2706 Question-Answer pairs
- 5 domains: Finance, Sports, Music, Movie, and Open domain
- 8 types of questions (see image below): simple, simple with condition, set, comparison, aggregation, multi-hop, post-processing heavy, and false premise
The datasets `crag_task_1_and_2_dev_v4_subsample_*.json.bz2` have been created from the dataset [crag_task_1_and_2_dev_v4.jsonl.bz2](https://github.com/facebookresearch/CRAG/raw/refs/heads/main/data/crag_task_1_and_2_dev_v4.jsonl.bz2?download=) available on CRAG's GitHub repository.
For an easier handling and download of the dataset, we have used the script [crag_to_subsamples.py](https://huggingface.co/datasets/Quivr/crag/blob/main/crag_to_subsamples.py) to split the 2706 rows of the original file in 5 subsamples, following the procedure below:
1. We have created a new label `answer_type`, classifying the answers in 3 categories:
- `invalid` for any answer == "invalid question"
- `no_answer` for any answer == "i don't know"
- `valid` for any other answer
2. We have considered the labels `answer_type`, `domain`, `question_type` and `static_or_dynamic` and performed stratified sampling, splitting the datasets in 5 subsamples. Each subsample has thus the same statistical properties of the full dataset.
We report below the data schema as provided in [CRAG's GitHub repository](https://github.com/facebookresearch/CRAG/blob/main/docs/dataset.md).
## Data Schema
| Field Name | Type | Description |
|------------------------|---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `interaction_id` | string | A unique identifier for each example. |
| `query_time` | string | Date and time when the query and the web search occurred. |
| `domain` | string | Domain label for the query. Possible values: "finance", "music", "movie", "sports", "open". "Open" includes any factual queries not among the previous four domains. |
| `question_type` | string | Type label about the query. Possible values include: "simple", "simple_w_condition", "comparison", "aggregation", "set", "false_premise", "post-processing", "multi-hop". |
| `static_or_dynamic` | string | Indicates whether the answer to a question changes and the expected rate of change. Possible values: "static", "slow-changing", "fast-changing", and "real-time". |
| `query` | string | The question for RAG to answer. |
| `answer` | string | The gold standard answer to the question. |
| `alt_ans` | list | Other valid gold standard answers to the question. |
| `split` | integer | Data split indicator, where 0 is for validation and 1 is for the public test. |
| `search_results` | list of JSON | Contains up to `k` HTML pages for each query (`k=5` for Task #1 and `k=50` for Task #3), including page name, URL, snippet, full HTML, and last modified time. |
### Search Results Detail
| Key | Type | Description |
|----------------------|--------|---------------------------------------------------------|
| `page_name` | string | The name of the webpage. |
| `page_url` | string | The URL of the webpage. |
| `page_snippet` | string | A short paragraph describing the major content of the page. |
| `page_result` | string | The full HTML of the webpage. |
| `page_last_modified` | string | The time when the page was last modified. | |
