Project Overview
The Bank Customer Service Classification Bot represents a sophisticated approach to automated customer service, utilizing a multi-agent architecture built with LangGraph workflows. This system intelligently processes customer inquiries, classifies them by urgency and category, routes them to appropriate handlers, and provides automated responses while seamlessly escalating complex issues to human agents.
Designed specifically for banking environments where accuracy, security, and compliance are paramount, this system handles thousands of daily customer interactions while maintaining high satisfaction rates and reducing operational costs.
Technology Stack
Four-Agent Architecture
Classification Agent
Analyzes incoming customer inquiries using NLP techniques to categorize requests by type (account, loans, cards, etc.), urgency level, and required expertise level. Achieves 95%+ accuracy in classification tasks.
Routing Agent
Intelligently routes classified inquiries to the most appropriate handling mechanism based on complexity, urgency, and available resources. Optimizes for response time and resolution quality.
Response Agent
Generates contextually appropriate automated responses for routine inquiries, accessing bank policies and procedures to provide accurate, compliant information while maintaining a conversational tone.
Handoff Agent
Manages escalation to human agents when automated resolution isn't appropriate, providing comprehensive context summaries and recommended next steps to ensure seamless transitions.
Key Features & Capabilities
- Intelligent Intent Recognition: Advanced NLP models accurately identify customer intent from natural language queries
- Multi-Language Support: Processes inquiries in multiple languages with automatic translation capabilities
- Sentiment Analysis: Detects customer emotions and adjusts response tone and escalation protocols accordingly
- Compliance Integration: Built-in regulatory compliance checks ensure all responses meet banking industry standards
