ProMiNER Russian BioNNE-L Reranker

Final cross-encoder reranker for Russian BioNNE-L entity linking.

This model is part of ProMiNER, a Russian-track biomedical entity-linking system for BioNNE-L. The system links mentions from NEREL-BIO/BioNNE-L texts to UMLS concepts by combining dense retrieval and cross-encoder reranking.

• Model type: sentence-transformers-cross-encoder
• Base/initializer: bikingSolo/prominer-ru-pretrained-cross-encoder

Training

Fine-tuned on candidate lists produced by the ProMiNER dense retriever, initialized from the dictionary-pretrained cross-encoder, and optimized with LambdaLoss. This is the best final model in the repository.

Evaluation

Metrics below are copied from the local MLflow run artifacts.

Usage

from sentence_transformers import CrossEncoder

model = CrossEncoder("bikingSolo/prominer-ru-reranker", num_labels=1)
scores = model.predict([
    (
        "вестибулокохлеарный нерв",
        "слуховой нерв; вестибулокохлеарный нерв; nervus vestibulocochlearis [viii]",
    )
])

Intended Use

This checkpoint is intended for research and reproducibility of the ProMiNER BioNNE-L Russian entity-linking pipeline. For the full system, use:

1. prominer-ru-retriever to retrieve candidate UMLS concepts.
2. prominer-ru-reranker to rerank those candidates with candidate-context profiles.

The dictionary-pretrained cross-encoder is primarily an intermediate checkpoint used to initialize the final reranker.

Data and Citation

Training and evaluation use BioNNE-L/NEREL-BIO resources and UMLS-derived terminology available in this repository's data layout. Cite the relevant NEREL-BIO and BioNNE-L papers when using this model.
