Chatbot & AI Agent Creation

📚 Complete Service Documentation​

Build production-ready chatbots and AI agents with LangGraph, Rasa, and our existing infrastructure.

🎯 What Is This?​

A complete chatbot platform that combines:

  • Intent Recognition (Rasa NLU)
  • Entity Extraction (spaCy)
  • Dialogue Management (Rasa Core)
  • Agent Orchestration (LangGraph - existing)
  • Memory System (SQLite - existing)
  • RAG Pipeline (Hybrid retrieval - existing)

🚀 Quick Start​

Try the Demo (2 minutes)​

# Install dependencies
pip install streamlit spacy
python -m spacy download en_core_web_lg

# Run interactive demo
streamlit run examples/chatbot/streamlit_demo.py

Open: http://localhost:8501

Try these queries:

  • "Hello!"
  • "I need help with medical records"
  • "Tell me about HIPAA compliance"

🎯 Use Cases​

Medical Knowledge Assistant​

# User: "I need information about diabetes"
# Intent: medical_query
# Entities: {"CONDITION": "diabetes"}
# → Routes to Medical Agent

Compliance Assistant​

# User: "Tell me about HIPAA requirements"
# Intent: compliance_query
# Entities: {"REGULATION": "HIPAA"}
# → Routes to Compliance Agent

IT Support​

# User: "I can't log into my account"
# Intent: it_support
# Entities: {"ISSUE_TYPE": "login"}
# → Routes to IT Support Agent

🔌 Integration Guide​

Step 1: Install Dependencies​

pip install -r requirements_chatbot.txt

Step 2: Add to Your API​

# In apps/api/main.py
from apps.api.chatbot_api import router as chatbot_router

app.include_router(chatbot_router)

Step 3: Test​

curl -X POST "http://localhost:8000/chatbot/message" \
  -H "Content-Type: application/json" \
  -d '{"message": "Hello!", "user_id": "test"}'

📚 Examples​

Basic Usage​

from packages.conversational import IntentRecognizer

recognizer = IntentRecognizer()
result = recognizer.recognize("I need medical help")

print(f"Intent: {result.intent}")
print(f"Confidence: {result.confidence:.2%}")

With Dialogue Management​

from packages.conversational import DialogueManager

manager = DialogueManager()
context = manager.start_conversation("user123")

action = manager.process_message(
    context,
