What data for this category looks like
Data for this category comes from publicly listed financing announcements, industry self-regulatory organization disclosures, and third-party compliant financing databases. The update frequency is daily. Each day, full financing entries for the previous calendar day are produced. Most documents are structured tables or text with fixed headers, and include fields such as financing entity name, financing round, financing amount, investor list, and disclosure date. Amount units are mostly ten thousand or hundred million RMB. Date fields use the Gregorian year-month-day format.
What constraints do these characteristics impose on document parsing and chunking
Daily updated bulk data requires parsing processes to have low latency, to avoid single-file processing timeouts disrupting subsequent business workflows. Structured table formats require parsing modules to first identify the correspondence between headers and cells, to prevent field misalignment that causes information loss. Financing amounts may use mixed units, so unit normalization must be completed during parsing to avoid inconsistent units in post-chunking entries. A single daily report file contains dozens to hundreds of independent financing entries. Chunking must use individual financing information as the smallest unit, to avoid cross-entry splitting that breaks context and harms retrieval accuracy.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | A single software development financing daily report file contains dozens of entries. Average processing time for bulk batches is approximately 150 seconds, with reasonable buffer time reserved. |
CHUNK_SIZE | 800–1200 characters | The average length of a single financing entry is 500–900 characters. This range ensures that a single chunk contains a complete entry with tight contextual association. |
ENABLE_TABLE_PARSING | Enabled | Financing daily reports mostly use structured table formats. Enabling this setting accurately maps headers and cell content, avoiding field misalignment. |
OCR_PRECISION_MODE | High-precision mode | Some financing announcements are scanned documents or encrypted PDF files. High-precision mode improves recognition accuracy for printed text and complex layouts. |
CHUNK_SPLIT_RULE | Split by independent entries | Each financing entry is an independent analysis unit. Splitting by entry avoids contextual breaks across entries. |
MAX_UPLOAD_FILE_SIZE | 50 MB | A single financing daily report file typically does not exceed 10 MB. This setting prevents invalid large files from consuming parsing resources. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: In a private deployment scenario, the platform returns a
504 Gateway Timeouterror after markerpdf parsing completes. Cause: The `PARSEFILETIMEOUTSECONDS` configuration value is lower than the actual parsing time, causing the platform to terminate the request actively. - Phenomenon: After enabling
OCR_PRECISION_MODE, the parsing log shows the errorOCR Error: Failed to recognize table structure. Cause: TheENABLE_TABLE_PARSINGconfiguration is not enabled, or the scanned document has severe layout confusion that prevents high-precision OCR from identifying the table framework. - Phenomenon: After a platform update, the
miner-u parsingoption does not appear in the front-end interface. Cause: Third-party parsing plugin integration is not enabled in system configuration, or the plugin version is incompatible with the current platform version.
How to confirm configurations are correct
- Upload a standard-format software development financing daily report PDF or document, check if all headers and financing entry fields are fully extracted in the parsed text.
- View the parsing log to confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration does not trigger timeout errors, and the OCR module has no abnormal errors. - Adjust the
CHUNK_SIZEparameter, compare chunking results across different values, and confirm that no chunk splits across financing entries. - Test batch uploading multiple daily report files, confirm that parsing times meet expectations, and there are no batch processing failures.
