What the data for this category looks like
Footwear industry research report data sources include supply chain monitoring reports from industry associations, publicly available new product research reports from brands, sales movement data summaries from retail platforms, and segmented category analysis from third-party consulting firms. Update cycles primarily follow quarterly regular reports, paired with temporary new product launch reports and monthly sales movement updates. Most documents use a mixed text and image layout, including nested tables, sales trend charts, cost proportion pie charts, and some are in scanned document format. Fields include SKU codes, unit cost per pair, shipment volume, gross profit margin, and more. Units involve pairs, ten thousand yuan, percentage, and similar metrics.
What constraints do these characteristics impose on the "document parsing and chunking" link
Nested multi-column industry tables can cause row splitting misalignment in general parsing engines, losing hierarchical relationships between fields. If mixed text and image layouts are not accurately preserved, the binding relationship between text descriptions and corresponding charts will be lost. Scanned format research reports rely on OCR recognition; failing to enable this function will directly result in lost plain text and table content. Segmented fields have clear units. If context association is not retained during chunking, fields and their values will disconnect during retrieval, making accurate query matching impossible.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Footwear industry research reports often contain nested tables and scanned OCR content. Extending the timeout avoids terminating parsing before it completes |
chunk_size | 800–1200 characters | Preserve contextual association for individual product test data or single tables, avoiding splitting fields and their units |
PARSE_PDF_MODE | "accurate" | For mixed text and image footwear research reports, the accurate mode better preserves the layout structure of tables and text |
enable_ocr | Enabled | Adapt to some scanned format footwear research reports, extract embedded table and text content |
OCR_LANGUAGE | "zh-en" | Footwear industry research reports often contain mixed Chinese and English brand names and material terms, supporting bilingual recognition |
preserve_table_structure | Enabled | Retain the complete structure of multi-dimensional SKU, cost, and shipment volume tables, avoiding field misalignment |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: After uploading a scanned footwear industry research report, the parsing result is empty or only contains a small amount of garbled text. Cause: The
enable_ocrconfiguration item is not enabled, and OCR parsing for scanned documents is not activated. - Symptom: A
504 Gateway Timeouterror is returned when parsing large footwear industry research reports. Cause: ThePARSE_FILE_TIMEOUT_SECONDSsetting value is lower than the actual parsing time, and does not adapt to the duration required for nested table and OCR processing. - Symptom: Unitless results such as "unit cost per pair is 30" appear during retrieval. Cause: The
preserve_table_structureconfiguration is not enabled, and the association with the "yuan per pair" unit field is lost when splitting tables.
How to confirm the configuration is correct
- Upload a scanned footwear industry research report, check whether the parsing result contains complete table and text content to verify that the
enable_ocrconfiguration is active. - Upload a footwear industry research report containing nested tables, check whether the chunked result retains the complete structure of the table and the association between fields and their units, confirming that the
preserve_table_structureconfiguration is active. - Adjust the
chunk_sizeparameter, check whether the chunked result does not split the contextual association of individual product test data, verifying the adaptability of the chunk length. - Test uploading a single large footwear industry research report, confirm that the parsing process does not trigger a timeout error, verifying the rationality of the
PARSE_FILE_TIMEOUT_SECONDSsetting.
