# π KoE5 |
|
|
|
Introducing KoE5, a model with advanced retrieval abilities. |
|
It has shown remarkable performance in Korean text retrieval, speficially overwhelming most multilingual embedding models. |
|
To our knowledge, It is one of the best publicly opened Korean retrieval models. |
|

|
### Python code |
|
Then you can load this model and run inference. |
|
```python |
|
from sentence_transformers import SentenceTransformer |
|
|
|
# Download from the π€ Hub |

## FAQ |
|
|
|
**- 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. |
