🧬 OpenMed-ZeroShot-NER-Oncology-Tiny-60M

Specialized model for Cancer Genetics - Cancer-related genetic entities

📋 Model Overview

Oncology-focused model for cancer genetics, capturing genes, variants, and cellular processes in tumor biology contexts.Useful for cancer pathway curation, driver gene analysis, and precision oncology literature mining.

OpenMed ZeroShot NER is an advanced, domain-adapted Named Entity Recognition (NER) model designed specifically for medical, biomedical, and clinical text mining. Leveraging state-of-the-art zero-shot learning, this model empowers researchers, clinicians, and data scientists to extract expert-level biomedical entities—such as diseases, chemicals, genes, species, and clinical findings—directly from unstructured text, without the need for task-specific retraining.

Built on the robust GLiNER architecture and fine-tuned on curated biomedical corpora, OpenMed ZeroShot NER delivers high-precision entity recognition for critical healthcare and life sciences applications. Its zero-shot capability means you can flexibly define and extract any entity type relevant to your workflow, from standard biomedical categories to custom clinical concepts, supporting rapid adaptation to new research domains and regulatory requirements.

Whether you are working on clinical NLP, biomedical research, electronic health record (EHR) de-identification, or large-scale literature mining, OpenMed ZeroShot NER provides a production-ready, open-source solution that combines expert-level accuracy with unmatched flexibility. Join the OpenMed community to accelerate your medical text analytics with cutting-edge, zero-shot NER technology.

🎯 Key Features

• Zero-Shot Capability: Can recognize any entity type without specific training

• Domain-Specific: Fine-tuned on curated BIONLP2013_CG dataset
• Production-Ready: Validated on clinical benchmarks
• Easy Integration: Compatible with Hugging Face Transformers ecosystem
• Flexible Entity Recognition: Add custom entity types without retraining

🏷️ Supported Entity Types

This zero-shot model can identify and classify biomedical entities, including but not limited to these entity types. You can also add custom entity types without retraining the model:

• Amino_acid
• Anatomical_system
• Cancer
• Cell
• Cellular_component

See 11 more entity types...

• Developing_anatomical_structure
• Gene_or_gene_product
• Immaterial_anatomical_entity
• Multi-tissue_structure
• Organ
• Organism
• Organism_subdivision
• Organism_substance
• Pathological_formation
• Simple_chemical
• Tissue

💡 Zero-Shot Flexibility: As a GliNER-based model, you can specify any entity types you want to detect, even if they weren't part of the original training. Simply provide the entity labels when using the model, and it will adapt to recognize them.

📊 Dataset

BioNLP 2013 CG corpus targets cancer genetics entities for oncology research and cancer genomics.

The BioNLP 2013 CG (Cancer Genetics) corpus is a specialized dataset focusing on cancer genetics entities and gene regulation in oncology research. This corpus contains annotations for genes, proteins, and molecular processes specifically related to cancer biology and tumor genetics. Developed for the BioNLP Shared Task 2013, it supports the development of text mining systems for cancer research, oncological studies, and precision medicine applications. The dataset is particularly valuable for identifying cancer-related biomarkers, tumor suppressor genes, oncogenes, and therapeutic targets mentioned in cancer research literature. It serves as a benchmark for evaluating NER systems used in cancer genomics, personalized medicine, and oncology informatics.

🚀 Quick Start

Installation

pip install -q "gliner[tokenizers]"

Usage

from transformers import pipeline

# Load the model and tokenizer
# Model: https://huggingface.co/OpenMed/OpenMed-ZeroShot-NER-Oncology-Tiny-60M
model_name = "OpenMed/OpenMed-ZeroShot-NER-Oncology-Tiny-60M"

from gliner import GLiNER
model = GLiNER.from_pretrained(model_name)

# Example usage with default entity types
text = "Mutations in KRAS gene drive oncogenic transformation."

labels = ['Amino_acid', 'Anatomical_system', 'Cancer', 'Cell', 'Cellular_component', 'Developing_anatomical_structure', 'Gene_or_gene_product', 'Immaterial_anatomical_entity', 'Multi-tissue_structure', 'Organ', 'Organism', 'Organism_subdivision', 'Organism_substance', 'Pathological_formation', 'Simple_chemical', 'Tissue']
entities = model.predict_entities(text, labels, flat_ner=True, threshold=0.5)
for entity in entities:
    print(entity)

Zero-Shot Usage with Custom Entity Types

💡 Tip: If you want to extract entities that are not present in the original training set (i.e., use custom or rare entity types), you may get better results by lowering the threshold parameter in model.predict_entities. For example, try threshold=0.3 or even lower, depending on your use case:

# You can specify custom entity types for zero-shot recognition - for instance:
custom_entities = ["MISC", "Amino_acid", "PERSON", "LOCATION", "MEDICATION", "PROCEDURE"]

entities = model.predict_entities(text, custom_entities, flat_ner=True, threshold=0.1)
for entity in entities:
    print(entity)

Lowering the threshold makes the model more permissive and can help it recognize new or less common entity types, but may also increase false positives. Adjust as needed for your application.
