SynCABEL: Synthetic Contextualized Augmentation for Biomedical Entity Linking

SynCABEL

SynCABEL is a novel framework that addresses data scarcity in biomedical entity linking through synthetic data generation. The method, introduced in our [paper]

SynCABEL (QUAERO-EMEA Edition)

This is a finetuned version of LLaMA-3-8B trained on QUAERO-EMEA using SynthQUAERO (our synthetic dataset generated via the SynCABEL framework).


Base Model	meta-llama/Meta-Llama-3-8B-Instruct
Training Data	QUAERO-EMEA (real) + SynthQUAERO (synthetic)
Fine-tuning	Supervised Fine-Tuning

Training Data Composition

The model is trained on a mix of human-annotated and synthetic data:

QUAERO-EMEA (human)   : 7,159 mentions
SynthQUAERO (synthetic)  : 396,914 mentions

To ensure balanced learning, human data is upsampled during training so that each batch contains:

50% human-annotated data
50% synthetic data

In other words, although SynthMM is larger, the model always sees a 1:1 ratio of human to synthetic examples, preventing synthetic data from overwhelming human supervision.

Usage

Loading

python

import torch
from transformers import AutoModelForCausalLM

# Load the model (requires trust_remote_code for custom architecture)
model = AutoModelForCausalLM.from_pretrained(
    "AnonymousARR42/SynCABEL_QUAERO_EMEA",
    trust_remote_code=True,
    device_map="auto"
)

Unconstrained Generation

python

# Let the model freely generate concept names
sentences = [
    "Le patient atteint de [Embolie pulmonaire massive]{Disorders} a présenté des signes de détresse respiratoire.",
    "Le patient reçoit régulièrement des [corticoïdes]{Chemicals & Drugs} pour soulager les symptômes cutanés."
]

results = model.sample(
    sentences=sentences,
    constrained=False,
    num_beams=2,
)

for i, beam_results in enumerate(results):
    print(f"Input: {sentences[i]}")

    mention = beam_results[0]["mention"]
    print(f"Mention: {mention}")

    for j, result in enumerate(beam_results):
        print(
            f"Beam {j+1}:\n"
            f"Predicted concept name:{result['pred_concept_name']}\n"
            f"Predicted code: {result['pred_concept_code']}\n"
            f"Beam score: {result['beam_score']:.3f}\n"
        )

Constrained Decoding (Recommended for Entity Linking)

python

# Constrained to valid biomedical concepts
sentences = [
    "Le patient atteint de [Embolie pulmonaire massive]{Disorders} a présenté des signes de détresse respiratoire.",
    "Le patient reçoit régulièrement des [corticoïdes]{Chemicals & Drugs} pour soulager les symptômes cutanés."
]

results = model.sample(
    sentences=sentences,
    constrained=True,
    num_beams=2,
)

for i, beam_results in enumerate(results):
    print(f"Input: {sentences[i]}")

    mention = beam_results[0]["mention"]
    print(f"Mention: {mention}")

    for j, result in enumerate(beam_results):
        print(
            f"Beam {j+1}:\n"
            f"Predicted concept name:{result['pred_concept_name']}\n"
