Document Parsing and Chunking for Footwear Industry Research Report Retrieval

Footwear industry research report data sources include supply chain monitoring reports from industry associations, publicly available new product

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.

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 ItemRecommended ValueRationale
PARSE_FILE_TIMEOUT_SECONDS120 secondsFootwear industry research reports often contain nested tables and scanned OCR content. Extending the timeout avoids terminating parsing before it completes
chunk_size800–1200 charactersPreserve 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_ocrEnabledAdapt 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_structureEnabledRetain 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_ocr configuration item is not enabled, and OCR parsing for scanned documents is not activated.
  • Symptom: A 504 Gateway Timeout error is returned when parsing large footwear industry research reports. Cause: The PARSE_FILE_TIMEOUT_SECONDS setting 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_structure configuration 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_ocr configuration 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_structure configuration is active.
  • Adjust the chunk_size parameter, 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_SECONDS setting.
