Solution: AI-Powered Review Categorization

Our team developed an AI-driven categorization system using Python and Google Colab to analyze sentiment and classify customer reviews into meaningful categories. Key components of our approach included:

2. Data Preparation & Merging

• Merged original customer reviews with AI-generated classifications using a unique index field.
• Created a structured dataset incorporating:
  • Technician names
  • Service department (Plumbing, HVAC, Electrical)
  • Customer sentiment breakdown
  • AI-generated sentiment classifications
  • Whether a technician was mentioned in the review

3. Advanced Data Processing & API Integration

• Integrated AI models to process and refine data efficiently.
