🧪 Example Interactions

Click to see sample conversations

User: "My 2-year-old has been coughing for 3 days. Should I be worried?"

BioGPT: "🩺 Medical Information: A cough lasting 3 days in a 2-year-old can have several causes, including viral upper respiratory infections, which are common in young children. Monitor for additional symptoms such as fever, difficulty breathing, or changes in appetite. If the cough is accompanied by high fever (>39°C), rapid breathing, or the child appears unusually lethargic, medical evaluation is recommended.

⚠️ Important: This information is for educational purposes only. Always consult with qualified healthcare professionals for medical diagnosis, treatment, and personalized advice."

User: "What are the warning signs of dehydration in babies?"

BioGPT: "🩺 Medical Information: Warning signs of dehydration in infants include decreased wet diapers (fewer than 6 per day), dry mouth and tongue, sunken fontanelle (soft spot), lethargy or excessive fussiness, and skin that remains "tented" when gently pinched. Severe dehydration may present with sunken eyes, rapid heartbeat, and decreased responsiveness, requiring immediate medical attention.

⚠️ Important: This information is for educational purposes only. Always consult with qualified healthcare professionals for medical diagnosis, treatment, and personalized advice."

User: "Hello!"

BioGPT: "👋 Hello! I'm BioGPT, your medical AI assistant specialized in pediatric medicine. Please upload your medical data file first, then ask me any health-related questions!"

📚 Usage Guidelines

✅ Appropriate Uses

Educational medical information and research
Understanding pediatric symptoms and conditions
Learning about evidence-based treatment options

🔍 How It Works

Document Processing: Medical literature is intelligently chunked into semantically meaningful segments (~400 words each)
Embedding Generation: Each chunk is converted to 384-dimensional vectors using medical-optimized sentence transformers
Vector Storage: FAISS index enables millisecond similarity search across thousands of medical concepts
Query Processing: User questions are embedded and matched against the knowledge base using cosine similarity
Context Retrieval: Top 3 most relevant medical passages are extracted and ranked
Response Generation: BioGPT-Large synthesizes evidence-based answers from retrieved context with medical reasoning
Safety Filtering: All responses include appropriate medical disclaimers and professional consultation guidance
