## How to evaluate on this task

You can evaluate an embedding model on this dataset using the following code:

```python
import mteb

task = mteb.get_task("BrightProStackoverflowRetrieval")
model = mteb.get_model(YOUR_MODEL)
mteb.evaluate(model, task)
```

<!-- Datasets want link to arxiv in readme to autolink dataset with paper -->

## Citation

If you use this dataset, please cite the dataset as well as [mteb](https://github.com/embeddings-benchmark/mteb), as this dataset likely includes additional processing as a part of the [MMTEB Contribution](https://github.com/embeddings-benchmark/mteb/tree/main/docs/mmteb).
