Difficulties and limits
- Building a sophisticated RAG system that could understand user’s ambiguous queries and then elegantly find answers and relevant information from CR’s vast database of articles, ratings and reviews.
- making sure that AskCR could still respond in a few seconds rather than minutes
- Currently limited to categories and products examined by CR experts, with plans to expand coverage.
