Separate uncertain readings from implausible values with source evidence, typed Jev questions, and a prescription walkthrough.
An extraction pipeline can read a value correctly and still pass bad data downstream. A clearly printed extra zero survives excellent optical character recognition (OCR).
Using Unsiloed and TypeSafe’s Jev together helps us check for OCR failures and general mistakes in a document. Unsiloed extracts structured fields and locates them on the page. Jev judges the extracted information against focused questions. We can combine these results to decide which fields need review.
A Jev request separates the information it considers (state) from the decisions it makes (questions). In our workflow, state contains the records Unsiloed extracted and the context needed to interpret them. Each question tells Jev what to check and which answer type to return; it can also define criteria for the possible answers.
