</ul>

<h2>🎯 Purpose</h2>
<p><strong>BRIDGE-OPEN</strong> is a curated subset of the comprehensive <a href="https://huggingface.co/spaces/YLab-Open/BRIDGE-Medical-Leaderboard">BRIDGE Medical Leaderboard</a> that focuses exclusively on <strong>open-source clinical datasets</strong>. The datasets are accessible via the <a href="https://huggingface.co/datasets/YLab-Open/BRIDGE-Open">BRIDGE-Open dataset</a> on Hugging Face. While the full BRIDGE benchmark contains 87 clinical text tasks, BRIDGE-OPEN includes only those datasets that are freely accessible without restricted access requirements.</p>

<p>For more information about BRIDGE and the construction of this LLM benchmark, please visit the <a href="https://huggingface.co/spaces/YLab-Open/BRIDGE-Medical-Leaderboard">original BRIDGE Leaderboard Space</a>.</p>

<p>This leaderboard enables researchers and practitioners to:</p>
<ul>
    <li><strong>Evaluate LLMs on clinical tasks</strong> using publicly available data</li>
    <li><strong>Reproduce and verify results</strong> without data access barriers</li>
    <li><strong>Benchmark models fairly</strong> on the same open clinical datasets</li>
    <li><strong>Advance medical AI research</strong> through transparent evaluation</li>
</ul>

<h2>📊 What's Included</h2>
<p><strong>BRIDGE-OPEN</strong> contains <strong>50+ open-access clinical datasets</strong> spanning:</p>
<ul>
    <li><strong>9 Languages</strong>: English, Chinese, Spanish, Japanese, German, Russian, French, Norwegian, Portuguese</li>
    <li><strong>8 Task Types</strong>: Text classification, semantic similarity, normalization/coding, NER, NLI, event extraction, QA, summarization</li>
    <li><strong>14 Clinical Specialties</strong>: General medicine, cardiology, oncology, pharmacology, radiology, and more</li>
    <li><strong>6 Clinical Stages</strong>: From triage to discharge and administration</li>
</ul>

<h2>🏆 Three Evaluation Modes</h2>
<p>Each model is evaluated using three different inference strategies:</p>
<ol>
    <li><strong>Zero-Shot</strong>: Direct task completion without examples</li>
    <li><strong>Chain-of-Thought (CoT)</strong>: Step-by-step reasoning before final answer</li>
    <li><strong>Few-Shot</strong>: 5 example demonstrations for in-context learning</li>
</ol>

<h2>🚀 How to Evaluate Your Model</h2>
<h3>Option 1: Run Inference Locally</h3>
<ol>
    <li>Download the <a href="https://huggingface.co/datasets/YLab-Open/BRIDGE-Open">BRIDGE-Open dataset</a></li>
    <li>Run inference on your model</li>
    <li>Save predictions in the "pred" field for each sample</li>
    <li>Submit results via <a href="https://forms.gle/gU3GjSn9SqJRvs3b9">Google Form</a></li>
</ol>

<h3>Option 2: Request Evaluation</h3>
<p>Submit your model details via <a href="https://forms.gle/gU3GjSn9SqJRvs3b9">Google Form</a> and we'll evaluate it for you.</p>
<p><strong>Note</strong>: Due to computational constraints, there may be delays in processing submissions.</p>
