RAG chatbot errors traced to retrieval, not LLM; fixes detailed

Retrieval-augmented generation (RAG) chatbots can provide incorrect or fabricated answers due to issues in the retrieval or generation phases, rather than the language model itself. Common problems include failing to find relevant passages, retrieving incomplete or poor-quality information, or the model disregarding the provided context. Addressing these issues involves optimizing document chunking for semantic meaning, cleaning source content to remove boilerplate and outdated information, and implementing hybrid search that combines keyword and semantic matching. Additionally, instructing the model to strictly adhere to provided context, requiring citations, and setting thresholds for acceptable retrieval relevance can significantly improve answer accuracy.
