What this category of data looks like
Rural commercial bank financial report data originates from official regulatory disclosure platforms and the investor relations sections of individual banks. Quarterly reports are disclosed within 15 days following the end of a quarter. Annual reports are disclosed within four months following the end of a calendar year. Documents use structured tables as their core structure, including three core financial statements: balance sheet, income statement, and cash flow statement. They also include regulatory indicator modules such as non-performing loan ratio and liquidity ratio. Fields cover various business balances, revenue and expenditure amounts, and regulatory indicators. Amounts are mostly denominated in ten thousand RMB, while indicators use proportion as their unit.
What constraints do these characteristics impose on the citation source and traceability workflow
Official disclosure sources require traceability to match publicly available document versions, and unreleased internal data must not be cited. High-frequency quarterly and annual updates require the traceability system to regularly refresh financial report documents in the knowledge base, ensuring cited content aligns with the latest disclosed versions. The structured table format requires that row and column correspondences be retained during parsing. Without this, precise location of specific report rows and fields during traceability will not be possible. Dense regulatory and financial fields require filtering irrelevant content during traceability, to avoid confusing homonymous fields across different reports.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_STRUCTURE | Enabled | Rural commercial bank financial reports are mostly structured tables. Enabling this setting retains the correspondence between cells and fields, ensuring specific report rows can be located during traceability |
RECALL_TOP_K | Top 8 entries | Rural commercial bank financial reports have dense fields. Excessive recall leads to confusing traceability. 8 entries cover core regulatory indicators and financial data |
SIMILARITY_THRESHOLD | 0.75–0.85 | Financial report fields have high semantic similarity. A threshold that is too low recalls irrelevant reports, while a threshold that is too high misses matching entries |
UPLOAD_FILE_VALID_EXT | ["xlsx", "pdf", "csv"] | Disclosure formats for rural commercial bank financial reports are mostly Excel, PDF scans, or structured CSV files. Limiting valid formats prevents parsing failures |
DOC_REFRESH_INTERVAL | 90 days | Quarterly financial reports are updated each quarter. A 90-day refresh cycle covers the latest disclosed quarterly and annual reports |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Large annual financial report files require longer parsing time. 600 seconds prevents parsing interruptions due to timeout |
The parameter values provided on this page are common 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 Configuration Errors
- Phenomenon: After calling the knowledge base to answer questions related to rural commercial bank financial reports, the citation source list is empty or only displays general documents. Reason: The
PARSE_TABLE_STRUCTUREconfiguration is not enabled. Fields in structured financial reports cannot be accurately matched, causing the system to fail to locate corresponding document fragments. - Phenomenon: Raw table code is displayed in context citations instead of formatted report content. Reason: Table parsing parameters are not configured correctly, resulting in unformatted Excel cell markers remaining in parsed text, which cannot be rendered into standard formats.
- Phenomenon: The field name displayed in the citation source does not match the original financial report, or the database field associated with
sourceidis empty. Reason: The field extraction function is not enabled when uploading files, causing thefiledfield to not be correctly written to the knowledge base metadata, making accurate traceability impossible.
How to Verify Correct Configuration
- Upload a rural commercial bank quarterly financial report file, and check if the parsed text retains the row and column structure of the table to verify that the table parsing configuration is effective.
- Input a test question containing core regulatory indicators, and check if the citation source list includes the uploaded financial report file to verify that the recall and similarity threshold configurations are reasonable.
- View the metadata of the knowledge base document, confirm that the
sourceidandfiledfields exist and correspond to the original text fields to verify the field extraction configuration during upload. - Simulate two consecutive questions related to financial reports, and check if the citation sources associated with the context are updated with each conversation turn to verify that the conversation context configuration is correct.
