What is document chunking?

A retrieval system often divides documents into chunks.

Try this yourself

Find one sentence that depends on a preceding definition. Rewrite your chunk boundary so the definition travels with the sentence.

Check your understanding

A chunk should contain enough context to interpret its key claims. Small amounts of overlap can help, but also increase duplication and cost.

A mistake to avoid

Do not split tables so that values lose their column headings. A retrieved number without its unit or label can be misleading.

Before looking at the answer, write a short explanation and one example of your own. Finish by naming one limitation of the method. Use Mark as read when you are ready, or return to the previous lesson if a term is unclear.
