Question 350
A financial extractor interprets a dash in a statement as a negative sign even when it indicates an empty cell. Which few-shot contrast helps?
Explanation
Correct Answer
A statement may use a dash as a placeholder for an empty or inapplicable cell, while a genuine negative monetary amount has a minus sign or accounting notation. The few-shot pair should put both in one table and label the outputs differently, preserving the source row and column semantics. This makes the extractor examine context rather than apply a blanket token rule. Include a case where zero is explicitly printed so missing, zero and negative remain distinct values.
Incorrect Answers
Turning all parenthesized or dashed figures positive destroys accounting signs and can overstate balances. Parentheses often denote negatives, while a standalone dash may denote no value; the meaning depends on the statement's notation. A targeted demonstration should preserve both actual negative amounts and missing entries, with source spans. Bulk sign conversion is not a repair for confusing one placeholder with a negative number.
Replacing every dash with zero invents a measured amount where the statement may indicate unavailable, not applicable or blank data. Zero can affect totals and ratios differently from an unknown or absent field. Show the model an explicit zero, a negative amount and a dash placeholder and label each separately. The output schema should permit a missing or null state when the source does not provide a numeric value.
Dropping a column because one row contains a dash would lose valid figures in the other rows and change the financial statement's structure. The document still has meaningful data that should be retained with correct missing-value semantics. Keep the column, parse each cell using its notation and row context, and distinguish absent data from genuine negative values. The remedy is precise extraction, not removal of difficult evidence.
