What the data for this use case looks like
Financing daily report data comes from financing declaration systems across internal business units, credit receipts from cooperating financial institutions, and publicly disclosed financing announcements. Updates are released daily, covering all relevant financing updates from the previous workday. Most documents are structured tables, with fields including financing subject, financing type, financing scale, financing term, financing cost, arrival time, handling department, and others. Financing scale is measured in ten thousand yuan. Financing term is measured in months or natural days. Financing cost is marked as a numerical value. Some documents include supplementary explanation paragraphs tied to specific financing entries.
What constraints do these characteristics impose on document parsing and chunking
The high proportion of structured tables requires the parsing step to accurately identify table boundaries and cell correspondences. This prevents splitting associated content across cells. The daily high-frequency update property means each daily report includes financing entries from multiple subsidiaries. During chunking, content must be aggregated by business segment or financing subject. This avoids mixing entries across different subjects. Supplementary explanation paragraphs are mostly tied to specific financing entries. Content association must be retained during chunking, and individual entries cannot be split independently. The clear field hierarchy requires the parsing step to accurately map fields to their corresponding content. This prevents field misalignment or content loss.
How to Configure
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | Financing daily reports use structured tables as their primary content carrier. Table fields and entries must be fully extracted. |
SEGMENT_SPLITTER | Line break + "Financing Subject: " | Financing entries use "Financing Subject: " as their core starting identifier. Using this as the separator allows accurate aggregation of corresponding entries and supplementary explanations. |
MAX_SEGMENT_LENGTH | 800–1200 characters | The combined length of a single financing entry and its tied supplementary explanation paragraphs mostly falls within this range. This avoids merging multiple entries or over-splitting individual entries. |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Monthly summary financing daily report collections can reach large sizes. This setting supports batch upload and parsing requirements. |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Large financing daily reports with multiple tables require longer processing time. This prevents task interruption before completion. |
SEGMENT_OVERLAP_RATE | 10% | There is a small amount of associated preceding information between financing entries. Retaining a 10% overlap prevents context breaks. |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test with your own samples before finalizing settings.
Three Common Mistakes
- Issue: When uploading Excel-format financing daily report files, the system displays a prompt that the format is not supported, or table content is missing after parsing. Cause: The
PARSE_TABLE_ENABLEconfiguration item is not enabled, or parsing support for the corresponding file format is not activated. - Issue: After uploading a PDF-format financing daily report with a size of approximately 3MB, the parsing task returns a timeout error or status code
504. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to a value suitable for large table parsing, leading to processing timeout. - Issue: After configuring a custom separator and chunk length, the chunking result either merges multiple independent financing entries into one chunk, or splits a single financing entry into multiple chunks. Cause: The chunk length setting does not match the actual length of a single financing entry plus its supplementary explanation, or the custom separator does not accurately match the starting identifier of financing entries.
How to Confirm Proper Configuration
- A single test financing daily report file is uploaded. The parsed text preview is reviewed to confirm full extraction of table content with no cell splitting errors.
- The
SEGMENT_SPLITTERandMAX_SEGMENT_LENGTHparameters are manually adjusted. The same test file is uploaded, and the chunking result is compared against corresponding financing entries to confirm that the aggregation logic meets expectations. - Test files of different sizes are uploaded. Task status is checked to confirm that no timeout prompts appear during the parsing process.
- The parsed chunk list is reviewed. Supplementary explanation paragraphs and their corresponding financing entries are confirmed to be assigned to the same chunk or adjacent chunks, with no associated content breaks.
