Derives scheduling fields from the line item, including day_of_week 'Su', days_pattern '------S', air_time '09:38:00', and time_slot '9a-10a'.
What was measured
Semantic Field Enrichment
Are derived fields such as transaction_type, transaction_id, cheque_number, day patterns, and ad codes correctly classified or extracted beyond raw OCR?
decisive for this rankingtransformation
For this ranking, correctly identifying derived business fields is part of producing usable structured data, not just a nice extra. (3 of 3 judges)
What was given, what came back
Test input: Invoice PDF · pdf · group: business-document-extraction
Input — what we sent
A two-page broadcast advertising invoice PDF with nested header metadata, billing and remit addresses, and eight line items spanning a page break. It was used to stress hierarchical line-item extraction, amount precision, time/day parsing, code extraction, and summary validation.
Why this input is hard
- · Nested line-item hierarchy extraction
- · Multi-page continuity across a page break
- · Precision on large dollar amounts and totals
- · Parsing complex time slots and day patterns
- · Extraction of Ad IDs and reconciliation codes
- · Mapping structured metadata sections correctly
- · Financial summary validation
- · Handling political advertising compliance text
Output — unretouched

Extraction Accuracy◐ MixedRetains the source label in payment_terms, returning 'Payment Terms 30 Days' instead of only the requested value, so the field is not fully normalized.Extraction Accuracy✓ WorkedExtracts the invoice summary totals correctly, including agency_commission 4462.5, aired_spots 8, gross_total 29750, and net_amount_due 25287.5.Extraction Accuracy✓ WorkedExtracts invoice metadata with machine-readable values such as invoice_number 4064621-1, invoice_date 2012-10-28, invoice_period_start 2012-10-01, and advertiser_code 155.Schema Adherence✓ WorkedReconstructs the invoice schema into nested invoice_metadata, advertiser, station, account_details, billing_address, remit_address, flight_dates, line_items, and summary sections rather than returning a flat document dump.Structural Clean Output⚠ StruggledPreserves valid JSON but does not keep the schema's original key order, so downstream consumers that expect schema-consistent ordering need an extra formatting step.Table & Record Completeness✓ WorkedExtracts all 8 advertising line items as separate structured records without duplication or omission.

Datalab✓ WorkedCaptures derived invoice line-item fields correctly, including time_slot 9a-10a, day_of_week Su, air_time 9:38 AM, and ad_id NRCCWI071005 on line item 2.Docsumo✓ WorkedThe tool correctly splits compound scheduling data for all 8 line items, with Day of Week and Day Pattern both populated correctly instead of being garbled together.Extend AI✓ WorkedThe tool correctly derives higher-level line-item fields such as `day_of_week: Tu` and `days_pattern: -T----` alongside ad ID, reference number, and flight-period dates.Landing AI✓ WorkedPopulates derived scheduling fields such as day_of_week "M" and days_pattern "MTWT" on invoice line items.LlamaParse✓ WorkedThe tool correctly extracts derived scheduling and coding fields for invoice line items, including day_of_week, days_pattern, air_time, ad_id, time_slot, and flight-period references.Nanonets✗ FailedPartially extracts line 8's schedule metadata: flight_period_start, flight_period_end, frequency, and days_pattern are null even though the source row and other records contain scheduling information.Reducto✓ WorkedCorrectly derives higher-level invoice metadata such as invoice_month, invoice_period_start, and invoice_period_end alongside invoice_number and order_number, showing semantic field extraction beyond raw OCR text.Unstract⚠ StruggledMis-reproduces the fixed-width day_of_week scheduling mask, with examples like MTWT- for source MTWT--- and F- - for source ----F--; the report says days_pattern is the more reliable field.
