Project Demo

Python

FastAPI

Streamlit

🌟 Features

• Multi-dimensional Scoring: Combines sentiment analysis (35%), keyword detection (45%), and customer tier (20%)
• Real-time Classification: Instant ticket prioritization with detailed scoring breakdown
• Visual Interface: Professional Streamlit web app with interactive results
• Smart Edge Cases: Handles complex scenarios like "urgently excited" messages
• Customer Tier Support: Different priority multipliers for Standard, Premium, and Enterprise customers
• Keyword Detection: 30+ critical, high-priority, and positive keywords
• API Documentation: Auto-generated OpenAPI/Swagger documentation

🎯 Priority Levels

• 🔴 Critical (>80%): Immediate action required
• 🟠 High (60-80%): Urgent attention needed
• 🟡 Medium (40-60%): Normal priority
• 🟢 Low (<40%): Can be scheduled

🚀 Quick Start

Prerequisites

• Python 3.9+
• Virtual environment (recommended)

Installation

1. Clone the repository

git clone <https://github.com/yourusername/ticket-prioritization-api.git>
cd ticket-prioritization-api

1. Create and activate virtual environment

python -m venv venv
# Windows
venv\\Scripts\\activate
# macOS/Linux
source venv/bin/activate

1. Install dependencies

pip install -r requirements.txt

Running the Application

1. Start the API server

python main.py

API will be available at: http://localhost:8000 Interactive docs: http://localhost:8000/docs

1. Start the web interface (in a new terminal)

streamlit run app.py

Web app will be available at: http://localhost:8501

📖 Usage Examples

API Endpoint

import requests

payload = {
    "ticket_id": "TKT-001",
    "text": "URGENT! Production database is down and customers are affected!",
    "customer_tier": "enterprise"
}

response = requests.post("<http://localhost:8000/classify-ticket>", json=payload)
result = response.json()

print(f"Priority: {result['priority']}")
print(f"Score: {result['final_score']:.1%}")

Web Interface

1. Select from pre-loaded examples or write custom ticket text
2. Choose customer tier (standard/premium/enterprise)
3. Click "Classify Ticket" to see results
4. View detailed scoring breakdown and detected keywords

🧠 Technical Architecture

Core Components

• FastAPI: REST API with automatic documentation
• Hugging Face Transformers: DistilBERT for sentiment analysis
• Custom Scoring Engine: Multi-dimensional priority calculation
• Streamlit: Interactive web interface

Scoring Algorithm

Final Score = (Sentiment × 0.35) + (Keywords × 0.45) + (Tier × 0.20)

Where:
- Sentiment: 0-1 based on negative sentiment confidence
- Keywords: 0-1 based on critical/high priority keywords detected
- Tier: Customer tier multiplier (Standard: 1.0, Premium: 1.15, Enterprise: 1.3)

Adjusting Scoring Weights

Modify weights in config.py:

WEIGHTS = {
    "sentiment": 0.35,      # Sentiment analysis weight
    "keywords": 0.45,       # Keyword detection weight
    "customer_tier": 0.20   # Customer tier weight
}
