From Ambiguous to AI-Ready: Improving Documentation Quality for RAG Systems | S2 E15

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.
