	## 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_tasks(["KorSTS"])
	evaluator = mteb.MTEB(task)

	model = mteb.get_model(YOUR_MODEL)
	evaluator.run(model)
	```

	<!-- Datasets want link to arxiv in readme to autolink dataset with paper -->
	To learn more about how to run models on `mteb` task check out the [GitHub repitory](https://github.com/embeddings-benchmark/mteb).

	## 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).
