Document processing and chunking

Methods to understand

Keep document identifiers, sections, page numbers, and versions. Preserve meaning when chunking and use overlap to retain context. Compare strategies using real queries rather than chunk counts alone.

Apply the method to a scenario

Query: "Does the project permit cross-department access to material?"
Record documents, sources, and answers; abstain without evidence.
Compare retrieval and citations before and after changes and record one failure.

Hands-on workshop

Turn documents into passages with traceable sources.

1. Choose three public documents and keep names, sections, and versions.
2. Create paragraph-based chunks and record chunk IDs and sources.
3. Use cross-passage questions to check whether chunking loses conditions.

const chunks = [
  { id: "doc-a-01", source: "Public specification A / section 1", version: "v1", text: "Users may read only authorized documents." },
  { id: "doc-a-02", source: "Public specification A / section 2", version: "v1", text: "Rebuild the retrieval index and retest after adding documents." }
];
// Keep source metadata alongside text for citations, updates, and authorization filters.

How to verify

For one question, identify the expected chunks, why they matter, and which context must be preserved.
