What is document parsing?

Document parsing converts a file's text, layout and metadata into structures a system can search. How well it works depends on the format and the file itself.

Where this one gets misread

Parsing sets the ceiling for everything downstream. Whatever it gets wrong is carried silently into retrieval, into the citation and into the answer, where it looks like a reasoning failure rather than an ingestion one.

02

Questions to ask

Ask for a worked example on your own material, and the evidence needed to reproduce it.

  • What is the failure signal on a bad file?
  • How are scans handled inside otherwise digital documents?
  • What happens to headers, footers and footnotes?
  • Can you inspect the parsed output?

How Marella uses the term

We use “Document parsing” only where a product mechanism or an evaluation method backs it up, and we say when the behaviour depends on how a deployment is configured.

  • Backed by a product mechanism or an evaluation method
  • Deployment differences flagged

What this page does not prove

  1. B1A definition is not a claim about how the product performs.
  2. B2Vendor implementations vary.
  3. B3Test the term against a representative workflow.
