Contextual chunk headers

The idea here is to add in higher-level context to the chunk by prepending a chunk header. This chunk header could be as simple as just the document title, or it could use a combination of document title, a concise document summary, and the full hierarchy of section and sub-section titles.

That is from the article. Is this different from your suggested approach?

No, but this is also not really a novel solution.
