Despite their high conversational fluency, large language models (LLMs) tend to produce responses that are either contrived or factually inaccurate, a phenomenon known as hallucination. This constrains their dependability in areas where accuracy is crucial, like customer service. This study leverages a context-aware chatbot built on a Retrieval-Augmented Generation (RAG) pipeline to solve the problem. The system retrieves semantically relevant text from an external knowledge base by integrating neural information retrieval with LLMs to ensure factual correctness and enhanced contextual relevance. These externally retrieved documents are given as a reference during response generation. The LL... More >
