What the Data for This Category Looks Like
Financial report data in professional service scenarios mainly comes from annual, semi-annual, quarterly reports publicly disclosed by listed companies, and temporary announcements from exchanges. It also includes internal audit working papers and customized financial report files commissioned by clients. The update rhythm is fixed: annual reports are updated once a year, semi-annual and quarterly reports are updated according to their respective cycles, and temporary announcements are released immediately when related events occur. The document structure is highly standardized, including fixed sections such as main financial statements, explanatory notes, and management discussion and analysis. The financial section mainly uses structured tables, containing core fields like assets, liabilities, and revenue. The unit is mostly RMB yuan or ten thousand yuan, and it also includes percentage indicators such as gross margin and growth rate.
Constraints Imposed on Document Parsing and Chunking by These Characteristics
The highly structured nature of financial reports requires the parsing process to retain table row and column structures, and avoid breaking the association between financial indicators and their corresponding values. Fixed section hierarchies require identifying separators such as "一、" and "（一）", to ensure that chunking does not destroy section integrity. Large-volume audit working papers and multi-page note documents require the parsing and chunking process to have sufficient memory and timeout fault tolerance. There are slight differences in field naming across financial reports of different enterprises, so precise matching is needed without forced replacement, and original unit information must be retained to avoid numerical confusion. The fragmented content of temporary announcements requires the chunking logic to adapt to mixed scenarios of short text and long paragraphs.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Professional service financial reports often include multi-page audit working papers and complete notes. 1000 MB covers the size requirements of most legally disclosed documents |
PARSE_TABLE_STRUCTURE | Enabled | Core financial report data is presented in structured tables. Enabling this parameter retains the original row and column structure, and avoids splitting and misplacing financial indicators and their values |
CUSTOM_SEGMENT_SPLITTER | , Level 1, Level 2, Level 3 | Matches the section hierarchy separators of financial reports, ensuring that chunking splits at section boundaries, and avoids cross-section merging or single-paragraph splitting |
MAX_SEGMENT_CHARS | 800–1200 characters | Adapts to the common length of financial report note paragraphs and table items. It retains contextual association while avoiding overly long single chunks that affect model understanding |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Parsing large-volume financial report files requires longer processing time. 600 seconds covers the parsing time of most legal documents |
ENABLE_EXCEL_PARSE | Enabled | Professional service scenarios often require importing Excel-format attachments of financial reports. Enabling this parameter directly parses table data without additional format conversion |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- The system returns a 413 status code error after uploading a 3 MB financial report PDF. Cause: The
UPLOAD_FILE_MAX_SIZEparameter configuration value is smaller than the actual file size, and does not adapt to the common size of professional service financial report files. - Setting the custom separator to only line breaks results in chunking results that either merge multiple note paragraphs or split a single financial table into multiple small chunks. Cause: The unique section separators of financial reports are not configured, and using only line breaks cannot identify structured sections and table boundaries, leading to failed chunking logic.
- An error occurs when processing financial report PDFs after deploying Marker, or a large number of empty fields appear in the parsing result when using the
qwen-plusmodel. Cause: ThePARSE_TABLE_STRUCTUREparameter is not enabled, and the original structure of financial report tables is not retained, leading to parsing timeout for large files or PDFs containing tables, or the model being unable to correctly identify the association between financial indicators.
How to Confirm the Configuration Is Correct
- Upload a single financial report PDF under 1000 MB, check whether the upload status shows success with no 413 status code error.
- Upload a financial report containing structured financial tables, check whether the parsed result retains the original row and column structure of the tables, with no garbled characters or misalignment.
- Set the custom separator to
, Level 1, Level 2, Level 3, upload a clearly segmented financial report, check whether the chunking result splits at section boundaries, with no cross-section merging or single-paragraph splitting. - View the parsing log, confirm that
PARSE_FILE_TIMEOUT_SECONDSdoes not trigger a timeout error, and the processing duration meets expectations.
