Does Nanonets keep a lookalike total row out of repeated-line-item extraction?

Nanonets passed this lookalike-row scenario. It returned five genuine line items and left out the lookalike Total row; the input table shows that row in the same layout, and the output has no 'Total' entry or 1,982 amount.

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.

What we sent

“Extract the following field from this document and return the result as JSON: line_items — an array of objects with description, quantity, unit_price, amount, for the genuine line items only.”

Why this result

The task asked for only genuine line items. The output has five matching members and leaves out the lookalike Total row, so this case passes.

Also observed in this test case

Number types. The exported quantities, unit prices and amounts were numbers, not strings.

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.

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.
