# MSMARCO dataset

A dataset in a [nixietune](https://github.com/nixiesearch/nixietune) compatible format:

```json
{
  "query": ")what was the immediate impact of the success of the manhattan project?",
  "pos": [
    {
      "doc": "The presence of communication amid scientific minds was equally important to the success of the Manhattan Project as scientific intellect was. The only cloud hanging over the impressive achievement of the atomic researchers and engineers is what their success truly meant; hundreds of thousands of innocent lives obliterated.",
      "score": 1
    }
  ]
}
```

This is the original converted dataset with the following splits:
* train: 502939 queries, only positives.
* test: 43 queries, positives and negatives.
* dev: 6980 queries, only positives.

## Usage

```python
from datasets import load_dataset

data = load_dataset('nixiesearch/msmarco', split="train")
```
