Challenges
- Limited In-Mall Navigation Support: Shoppers lacked intelligent tools to plan visits, navigate multiple stores, and discover relevant shops.
- Unstructured Mall Data: Shop and product data existed in fragmented, inconsistent formats that made automated recommendations difficult.
- Generic Chatbots: Traditional mall chatbots provided only scripted responses, with no personalization or context retention.
- Scalability & Data Retrieval Issues: Handling large amounts of shop data while maintaining quick response times required robust infrastructure and optimized retrieval.
The client needed a chat-based mall assistant that could provide personalized trip planning, shop recommendations, and real-time engagement powered by AI and RAG.
WhizzBridge’s Solution
- Knowledge-Driven Conversational AI: Integrated ChatGPT-4 with LangChain and PineconeDB to enable retrieval-augmented generation (RAG), ensuring accurate, context-aware shop recommendations.
- End-to-End Data Pipeline: Scraped mall and shop data with BeautifulSoup, cleaned it using Pandas/NumPy, and indexed it in PineconeDB for optimized embedding-based retrieval.
- Smart Recommendation Engine: Implemented ranking algorithms to suggest shops based on preferences, trip planning needs, and contextual queries.
- Memory & Continuity: Deployed Redis + LangChain Buffer Memory for personalized, continuous conversations, enabling contextual follow-ups and long-term personalization.
- Scalable Fullstack Architecture: Developed the backend in Flask, deployed with Docker containers, integrated with React frontend, and secured via MongoDB + Redis for analytics and chat storage.
- Performance & Monitoring: Optimized queries for real-time responses and designed modular architecture to support future LLM upgrades.
