What the Data for This Category Looks Like
Papermaking marketing data comes primarily from internal product specifications, quarterly marketing briefings, bidding cooperation plans, exhibition promotional materials, and customer quotation sheets. Update rhythms align with business scenarios: product specifications update irregularly alongside production process iterations, quarterly marketing briefings release on a quarterly basis, and bidding documents generate temporarily per project requirements. Document structures cover multiple types: plain text quotation sheets, PPT presentations with embedded charts, PDF brochures with integrated process parameters, and structured Excel data tables. Fields include quantitative values (g/㎡), thickness (μm), burst strength (kPa), delivery lead time (days), purchase volume (tons), and more. Some documents include customer-specific parameter descriptions.
Constraints on Document Parsing and Chunking
Parsing tools must support cross-format compatibility to handle multiple document types. This avoids missing structured parameters in PPT and Excel that would occur with PDF-only parsing logic. Fields that bind specific units to parameters require retaining contextual associations between parameters and units during chunking. Independent split extraction of these pairs must be prevented. Universally repeated product specifications across pages require filtering redundant content during chunking. This avoids repeated recall of duplicate information. Project-based bidding documents require chunking by project dimension. This ensures recalled content matches project requirements.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Papermaking marketing documents include process parameters bound to units. A value that is too long loses parameter context, while a value that is too short splits parameters from their corresponding units |
chunk_overlap | 100–150 characters | Retains associations of process parameters across pages or chunks, and avoids splitting continuous product specification descriptions |
enable_ocr | Enabled | Adapts to non-plain-text documents such as scanned brochures and PPTs with embedded charts, and extracts embedded process parameters |
parse_excel_sheet | Parse all valid worksheets | Papermaking quotation sheets often store parameters across worksheets by product category, avoiding the issue where the default configuration only extracts the first two columns of the first worksheet |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Large bidding documents or multi-page PPTs take longer to parse, preventing parsing failures due to timeout |
filter_repeat_chunk | Enabled | Filters repeatedly occurring universal product specification text, avoiding redundant recall |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on local samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After importing PPT or DOC documents, enabling
enable_pdf_enhanceresults in no charts or incomplete parameter extraction in parsing results. Cause:enable_pdf_enhanceonly applies to PDF format documents, and this enhancement logic cannot be triggered for non-PDF documents. - Phenomenon: After importing an Excel file, parsing results only extract data from the first two columns. Cause: The
parse_excel_sheetconfiguration was not adjusted, and the default logic only parses the first two columns of the first worksheet. - Phenomenon: Parsed text chunks split quantitative values from their corresponding units, resulting in incomplete parameter information. Cause: The
chunk_sizevalue is too small, splitting process parameters bound to units into two separate text chunks.
How to Verify Correct Configuration
- Upload a single papermaking marketing PDF document with process parameters, check the parsed text chunks, and confirm that quantitative values, burst strength and other parameters are not split from their corresponding units.
- Import an Excel quotation sheet with multiple worksheets, verify that the parsing result covers valid fields across all worksheets.
- Enable the
filter_repeat_chunkconfiguration, upload a document that repeatedly includes universal product specifications, and confirm that no redundant duplicate text chunks appear. - Test a scanned marketing brochure, and confirm that embedded parameter text extracts successfully after the OCR configuration is enabled.
