Documentation quality is the silent killer of RAG systems. A single ambiguous sentence might corrupt an entire set of responses. But the hardest part isn't fixing errors - it's finding them.

Today we are talking to Max Buckley on how to find and fix these errors.

Max works at Google and has built a lot of interesting experiments with LLMs on using them to improve knowledge bases for generation.

We talk about identifying ambiguities, fixing errors, creating improvement loops in the documents and a lot more.

Some Insights:

A single ambiguous sentence can systematically corrupt an entire knowledge base's responses. Fixing these "documentation poisons" often requires minimal changes but identifying them is challenging.
Large organizations develop their own linguistic ecosystems that evolve over time. This creates unique challenges for both embedding models and retrieval systems that need to bridge external and internal vocabularies.
Multiple feedback loops are crucial - expert testing, user feedback, and system monitoring each catch different types of issues.
