What KoE5 is

🔎 KoE5 Introducing KoE5, a model with advanced retrieval abilities. It has shown remarkable performance in Korean text retrieval. For details, visit the KURE repository Model Versions Model Description This is the model card of a 🤗 transformers model that has been pushed on the Hub. - Developed by: NLP&AI Lab - Language(s) (NLP): Korean, English - License: MIT - Finetuned from model: intfloat/multilingual-e5-large - Finetuned dataset: ko-triplet-v1.0 Example code Install Dependencies First install the Sentence Transformers library: Python code Then you can load this model and run inference. Training Details Training Data - ko-triplet-v1.0 - Korean query-document-hardnegative data pair (open data) - About 700000+ examples used totally Training Procedure - loss: Used CachedMultipleNegativesRankingLoss by sentence-transformers - batch size: 512 - learning rate: 1e-05 - epochs: 1 Evaluation Metrics - Recall, Precision, NDCG, F1 Benchmark Datasets - Ko-StrategyQA: 한국어 ODQA multi-hop 검색 데이터셋 (StrategyQA 번역) - AutoRAGRetrieval: 금융, 공공, 의료, 법률, 커머스 5개 분야에 대해, pdf를 파싱하여 구성한 한국어 문서 검색 데이터셋 - MIRACLRetrieval): Wikipedia 기반의 한국어 문서 검색 데이터셋 - PublicHealthQA): 의료 및 공중보건 도메인에 대한 한국어 문서 검색 데이터셋 - BelebeleRetrieval): FLORES-200 기반의 한국어 문서 검색 데이터셋 - MrTidyRetrieval: Wikipedia 기반의 한국어 문서 검색 데이터셋 - MultiLongDocRetrieval: 다양한 도메인의 한국어 장문 검색 데이터셋 - XPQARetrieval: 다양한 도메인의 한국어 문서 검색 데이터셋 Results 아래는 모든 모델의, 모든 벤치마크 데이터셋에 대한 평균 결과입니다. 자세한 결과는 KURE Github에서 확인하실 수 있습니다. Top-k 1 Top-k 3 Top-k 5 Top-k 10 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.

How embedding models work

Your textsentence / documentEncodermaps meaningVectorlist of numbersAn embedding model turns text into a vector, so similar meanings sit close together — the basis of search and RAG.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys koe5 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (koe5 below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"koe5","input":"text to embed"}'
