What the data for this category looks like
Packaging and printing enterprise financial report data mainly comes from publicly disclosed annual reports, semi-annual reports and quarterly reports. The update rhythm follows securities regulatory requirements: annual reports are disclosed by April of the following year, semi-annual reports by August of the current year, and quarterly reports within one month after the quarter ends. Most financial report documents are in PDF format, with fixed chapter structures. Content related to packaging and printing business is scattered across sections such as Management's Discussion and Analysis and Core Business Data. Fields include revenue breakdown, printing capacity, raw material purchase volume, order fulfillment cycle, and number of patents, with corresponding units of yuan, 10,000 square meters, tons, days, and pieces.
Constraints imposed on document parsing and chunking
The fixed chapter structure and scattered business data in financial reports require precise positioning of business modules related to packaging and printing during parsing, to avoid unfiltered full-document parsing. Differentiated units across different fields require retaining the association between fields and units during chunking, and not splitting combined data across fields. When batch processing multiple financial reports, adaptation to page count and content length of different documents is needed, to avoid single task timeout. Nested tables of capacity and raw material purchase details in financial reports require retaining table structure during parsing, to prevent chunking from destroying data integrity and relevance.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 1000–1500 characters | Business data paragraphs in packaging and printing financial reports usually contain multiple sets of related numerical values. This range can retain complete business context and avoid splitting single sets of indicators |
chunk_overlap | 100–150 characters | Retain overlapping content between adjacent chunks, avoid splitting associated data of raw material purchases and corresponding costs across chunks |
custom_separator | \n\n,## ,### | Separate by blank lines, second-level chapter headings, and third-level chapter headings in financial reports, accurately split content of different business modules |
enable_table_parse | Enabled | Packaging and printing financial reports include detailed tables of capacity and raw material purchases. Retaining table structure prevents chunking from destroying data relevance |
parse_timeout | 600 seconds | Adapt to the parsing duration of large annual reports of packaging and printing enterprises, avoid task timeout caused by large number of document pages |
upload_max_size | 500 MB | Adapt to the PDF file size of annual financial reports of packaging and printing enterprises, cover upload requirements for most large annual reports |
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 case-by-case analysis. It is recommended to test on local samples before finalizing the settings.
Three common mistakes
- Phenomenon: After manual segmentation by line breaks and configuration of
custom_separator, chunking results still merge multiple packaging and printing business paragraphs, or split single sets of revenue data. Cause: The custom separator does not include the chapter hierarchy markers of the financial report. The system prioritizes line break separation, and does not accurately split content by business modules. - Phenomenon: In the docker deployment configuration of open source version v4.8.17, processing packaging and printing financial report PDFs returns the error
{"detail":"Parsing failed"}. Cause: TheMARKER_PDF_DPIenvironment variable is not set to 300. Fine-line tables and charts in financial reports cannot be parsed normally. - Phenomenon: After table parsing is enabled, chunking results lose the corresponding relationship between raw material purchase unit price and usage. Cause: The overlap value of the
chunk_overlapparameter is not set, causing the chunk containing the table and preceding and following business descriptions to be split, losing associated context.
How to verify correct configuration
- Upload a single public financial report PDF of a packaging and printing enterprise, review system-generated chunking results, and confirm that each chunk does not split complete data of the same business module.
- Check running logs of parsing tasks, confirm that the table parsing function does not throw exceptions, and detailed table content is completely retained.
- Verify chunk metadata, confirm that each chunk is associated with the original document identifier and chapter title.
- Batch upload similar financial report documents, confirm that no parsing task timeout or parsing failure occurs.
