            <a href="https://semanticcite.com" target="_blank">🌐 Project Homepage</a>
        </div>

        <p>This Hugging Face Space hosts the complete SemanticCite project, including fine-tuned models, training dataset, and interactive demo for AI-powered citation verification.</p>

        </div>

        <p>SemanticCite transforms citation verification by analysing complete source documents and providing nuanced classification through four categories: Supported, Partially Supported, Unsupported, and Uncertain. Beyond simple validation, the system delivers detailed reasoning, confidence scores, and evidence reference snippets that show researchers exactly how their claims connect to the supporting literature.</p>

        <h2>✨ Key Features</h2>
        <div class="features">
            <ul>
                <li><strong>Deep Semantic Analysis:</strong> Full-text document analysis with 4-class classification (Supported, Partially Supported, Unsupported, Uncertain)</li>
                <li><strong>Lightweight AI Models:</strong> Fine-tuned Qwen3 models (1.7B & 4B parameters) with performance comparable to GPT-4</li>
                <li><strong>Triple Retrieval System:</strong> Dense vector search + sparse BM25 matching + neural reranking with FlashRank</li>
                <li><strong>Evidence-Based Reasoning:</strong> Ranked text snippets with transparent explanations and confidence scores</li>
                <li><strong>Multiple Deployment Options:</strong> Web interface, Python API, local/cloud deployment</li>
