Can Nanonets use a supplied definition to choose the right value?

Nanonets chose the consignment reference, not the invoice number, for this field. The result row and exported JSON both show CFS-CN-40821, matching the supplied definition.

The test case

Each test case is judged on its own: Pass, Fail, Not gradable, or Untested. The scenario result above is based on this test case.

Definition overrides the prominent numberPassEvidence
What we sent

“Extract the following field from this document and return the result as JSON: reference_number — defined as the consignment reference number (the identifier tied to the physical shipment), NOT the invoice number.”

Expected vs. Found
✓Expected: The field should return the value named by the supplied definition, not the more prominent candidate.Found: The invoice number CFS-7710 repeats in headers or footers on all three pages. Nanonets returned the defined consignment reference, CFS-CN-40821, and highlighted it.

Why this result

It is a Pass because the supplied definition selected the consignment reference, and the product returned that value instead of the invoice number. The same value appears in the result row, export, and highlighted line.

How this tool was set up for the run and what the test needed in place. Each row is a fact from the run's records; a fact the records do not hold is left out, not guessed.

A field extraction task had to use a supplied definition to choose between two plausible values, with the more prominent one excluded, in the web app.

How this scenario is graded

How we decide Pass, Fail and Not gradable. The same rules apply to every tool tested on this scenario.

How results are decided

Each test case gets one result per tool: Pass, Fail or Not gradable. A test case we haven't run yet shows Untested. There are no partial results.

The rules
  • Pass: the tool did everything the test expected, and nothing it said contradicts the correct answer.
  • Fail: at least one expected behaviour clearly didn't happen; the test case's result says which one and quotes the tool.
  • Not gradable: our evidence couldn't settle the outcome (for example a record we needed is missing). It is never counted as a fail, and the test case's result says what's missing.

Where this sits in the benchmark

This page is one cell of a larger study: one tool, one scenario. Only this benchmark's frame appears here.

History of this result

What has happened to this result since it was first published. Runs and grades are never overwritten: a retest or a re-grade publishes a new result and keeps the earlier one readable.

Act on this result

Nothing filed here edits the run or the grade. A challenge opens a review, and a review can produce a new run or a re-grade — which becomes the current result and leaves this one in the history.

This matches what I see

You run the same kind of test against your own setup and get the same behaviour.

We have fixed this

Tell us what changed and we schedule a rerun of the failing test case. The old result stays as history.
