What the data for this category looks like
Data sources for real estate construction project financing daily reports include project party fund supervision ledgers, loan receipts from cooperative financial institutions, and fund allocation vouchers from project general contractors. Update frequency adjusts based on project financing progress. Key under-construction projects are updated daily. Reserve projects are updated weekly. Most documents are in structured table format, with fields including project ID, project name, construction address, financing subject, lending bank, loan amount, arrival time, fund purpose, remaining financing quota, and more. Amounts are denominated in RMB yuan. Times are recorded in YYYY-MM-DD format. Project addresses consist of administrative division names plus specific plot numbers.
Constraints imposed on document parsing and chunking
A large number of structured fields are closely linked for real estate construction project financing daily reports. When chunking, all associated fields of a single financing record must not be split. Doing so breaks information integrity. Document formats vary across sources. Some files include complex structures such as merged cells and cross-page tables. Parsing logic must adapt to different table formats to avoid field misalignment or loss. Strongly formatted fields such as amounts and times are prone to recognition errors. Format validation must be completed during parsing to prevent unit recognition errors or time format chaos after chunking. Differing update schedules require distinguishing between incremental and full data during batch processing. Chunking logic must support filtering associated data by project cycle.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | A single financing record for real estate construction project financing daily reports contains 5-8 associated fields. This length can fully cover the core information of a single record and avoid splitting associated fields |
chunk overlap character count | 100–150 characters | Some financing daily reports have cross-page table content. Overlapping characters can ensure continuity of cross-chunk information and avoid splitting cross-page project financing data |
enable table merged cell parsing | Enabled | Real estate construction project financing daily reports often use merged cells to mark project categories. Enabling this can accurately identify the field attribution corresponding to merged cells and prevent field misalignment |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Financing daily report files for batch projects have large file sizes. This duration avoids parsing timeouts and adapts to multi-project batch upload scenarios |
structured field validation switch | Enabled | Financing daily reports contain strongly formatted fields such as amount and time. Enabling this can validate field formats during parsing to prevent unit recognition errors after chunking |
similarity threshold | 0.75–0.85 | Fields in real estate construction project financing daily reports have high similarity. This threshold can filter duplicate financing records while retaining differences in financing data for the same project across different cycles |
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, and it is recommended to test on your own samples before finalizing.
Three common mistakes
- Phenomenon: After upgrading the version, when parsing the same CSV-format real estate construction project financing daily report, the error
Cannot redefine property: toStringis thrown. Cause: The dependency package version of the parsing module is not aligned after the upgrade, and the old cached parsing script is not cleared, resulting in repeated definition of built-in object methods. - Phenomenon: The number of chunks after parsing a single real estate construction project financing daily report exceeds 3000, and the system triggers a chunk limit prompt. Cause: The
segment lengthparameter is not adjusted based on the field association characteristics of real estate financing daily reports, and an overly short chunk threshold is used, resulting in too many redundant chunks being split. - Phenomenon: In the parsed financing daily report documents, fields across merged cells (such as the loan amount corresponding to the project category) are empty or misaligned. Cause: The
enable table merged cell parsingconfiguration is not enabled, so the field attribution of merged cells is not correctly identified, and corresponding information is lost during chunking.
How to confirm configuration is set correctly
- A test document of real estate construction project financing daily report containing merged cells is uploaded, and the parsed field list is checked to confirm that the project category field corresponding to the merged cells has been correctly identified.
- 3-5 financing records are randomly selected, and the parsed chunk content is checked to confirm that it contains all associated fields of the record, with no cross-field splitting occurring.
- Time consumption statistics in the parsing log are reviewed to confirm that the single file parsing duration does not exceed the configured
PARSE_FILE_TIMEOUT_SECONDSthreshold, and no timeout errors are present. - The
segment lengthparameter is adjusted, the same test document is re-uploaded, and the change in the number of chunks is compared to confirm that the impact of parameter adjustment on chunk results meets expectations.
