## Uses

### Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

```bash
pip install -U sentence-transformers
```

Then you can load this model and run inference.
```python
from sentence_transformers import SentenceTransformer

# Download from the πŸ€— Hub
model = SentenceTransformer("nlpai-lab/KoE5")

# Run inference
sentences = [

## FAQ

**1. Do I need to add the prefix "query: " and "passage: " to input texts?**

Yes, this is how the model is trained, otherwise you will see a performance degradation.

Here are some rules of thumb:
- Use "query: " and "passage: " correspondingly for asymmetric tasks such as passage retrieval in open QA, ad-hoc information retrieval.

- Use "query: " prefix for symmetric tasks such as semantic similarity, bitext mining, paraphrase retrieval.

- Use "query: " prefix if you want to use embeddings as features, such as linear probing classification, clustering.
