What data for this category looks like
Residential development financial report data primarily comes from quarterly reports, annual reports, and special development progress announcements of real estate development enterprises. Updates follow fixed quarterly and annual cycles. Some special project reports are updated alongside development milestone progress. Most documents are in PDF format, containing nested tables, long text paragraphs, and structured data modules. Core fields include land reserve area, per-square-meter construction cost, pre-sale revenue amount, net cash flow, and others. Common units for these fields include square meters, yuan per square meter, ten thousand yuan, and other industry-specific units.
What constraints do these characteristics impose on the document parsing and chunking stage?
The nested table structure of residential development financial reports requires the parsing process to preserve row and column correspondence for tables, to avoid chaotic data splitting. Fixed-cycle batch upload requirements mean the parsing service must support batch rate limiting, to prevent long-term occupation of service resources. The combination of long text paragraphs and industry-specific units requires chunking to preserve contextual connections and unit field integrity, to avoid breaks in business logic. Some financial reports are scanned documents or encrypted formats, so the parsing process must support OCR recognition and format compatibility.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Single residential development financial report PDFs often exceed 80 pages, with long parsing times. This duration covers parsing needs for most documents |
UPLOAD_BATCH_MAX_SIZE | 10 documents/batch | When uploading multiple financial reports in batches, this batch size prevents long-term occupation of service resources and reduces interruption risks |
chunk_size | 800–1200 characters | Financial reports include long text project descriptions and nested tables. This range preserves business logic integrity and avoids truncation of critical information |
chunk_overlap | 150–200 characters | Related business data exists between financial report chapters. Overlapping chunks avoid contextual breaks and improve retrieval accuracy |
PARSE_TABLE_ENABLE | Enabled | Core financial report data is presented in table form. Enabling this preserves table structure and field correspondence, preventing data loss |
PARSE_PDF_OCR_MODE | Auto-detect | Adapts to scanned and encrypted financial report documents. Auto-detection covers more document types |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to the file size of single residential development financial reports, avoiding excessive memory usage |
The parameter values provided on this page are common recommendations used as starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: Parsing interruptions occur when uploading large batches of financial reports, and parsing cannot resume after restarting Docker. Cause: The
PARSE_FILE_TIMEOUT_SECONDSandUPLOAD_BATCH_MAX_SIZEparameters were not adjusted. Single-document parsing timeouts or batch overload cause service blocking. For the open-source version 4.9.2, check these parameter configurations first. - Issue: No parsing progress is displayed after uploading a file via the dialog box, and no corresponding parsing logs are generated in the background. Cause: The
PARSE_TABLE_ENABLEparameter was not enabled. Nested table parsing failures cause the process to stall without triggering an error prompt. - Issue: Knowledge base chunked content lacks unit fields, and retrieval results do not match business requirements. Cause: The association between fields and units was not preserved during chunking. Trailing characters related to units were truncated during splitting.
How to confirm configurations are set correctly
- Upload a single residential development financial report PDF with more than 100 pages, and check if parsing completes within the time set by
PARSE_FILE_TIMEOUT_SECONDS. - Review the chunked content after parsing, confirm that row and column data of nested tables matches the original document, and that unit fields are not split.
- Upload 10 financial report documents in a batch, confirm that the service does not block, and all documents complete parsing and are added to the repository.
- Call the knowledge base API to add chunked content, confirm that returned chunked data includes complete business fields and units.
