Your corpus is scanned PDFs, spreadsheets and slide decks. How do you ingest it?

Answer

Short answer

Route each format to a parser that respects its structure, treat OCR output as text with a confidence score rather than as truth, convert tables into rows that carry their headers, and record a section path and stable anchor per chunk so every retrieved passage can be cited back to a place in the original.

Likely follow-ups

  • A scanned page comes back as gibberish. How does that get caught before it reaches the index?
  • A spreadsheet has merged cells and three tables on one sheet. What do you do with it?
  • How do you handle a diagram on a slide whose meaning is entirely visual?
  • Which of these formats would you refuse to support in the first release, and how would you argue it?
