What Data for This Category Looks Like
Data sources for joint-stock commercial bank intelligent due diligence reports include internal credit approval archives, compliance documents submitted to regulatory authorities, public annual reports of listed entities, and inter-bank due diligence correspondence. Update cycles follow different schedules: internal archives are updated dynamically with credit cycles, public annual reports are updated annually, and regulatory documents are updated quarterly or when triggered by specific events. Document structures typically include four core modules: basic subject information, detailed financial indicators, compliance records, and collateral information. Fields include credit limit (unit: ten thousand yuan), days past due (unit: days), financial report disclosure date (format: YYYY-MM-DD), and others. Single document length typically ranges from thousands to tens of thousands of characters.
What Constraints These Characteristics Impose on Citation Sources and Traceability
Multi-source, heterogeneous data sources require traceability identifiers to mark both document source type and storage path. This prevents confusion between identically named fields from different sources. Long document structures require that chunk splitting preserves field integrity. Associated indicators and explanatory text must not be split apart. Data with varying update frequencies requires traceability information to include data generation time. This ensures timeliness can be verified when invoking the data. Fields with fixed units require traceability results to return unit information synchronously. This avoids ambiguity in indicator meanings.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
recall count | Top 8-12 entries | Joint-stock commercial bank due diligence reports have multiple data dimensions. This range balances recall coverage and result readability |
similarity threshold | 0.72-0.85 | Due diligence data fields have high strictness requirements. This range filters low-relevance recall results to ensure traceability accuracy |
reranked return count | Top 3-5 entries | Core due diligence information is concentrated in earlier document modules. This range prioritizes display of highly relevant traceability sources |
citation source field mapping | Map to "document name + update time + field name" | This matches the multi-dimensional traceability needs of bank due diligence data. It clearly marks information sources and timeliness |
chunk length | 1500-2000 characters | This adapts to the structural characteristics of long due diligence document paragraphs. It avoids splitting that disrupts the integrity of fields and associated text |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | This prevents parsing timeout leading to missing traceability information when processing long documents such as large credit archives |
The parameter values provided here are common 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 Misconfigurations
- Issue: When configuring a knowledge base search node in a workflow, using {{}} format to reference variables results in an empty citation list or parsing error. Cause: The configuration did not adapt to the fix update of FastGPT V4.8.18-FIX2, and did not switch to using / mode for variable retrieval.
- Issue: Traceability results returned by knowledge base search do not include the document update time field. Cause:
citation source field mappingwas not configured, and document metadata update time information was not associated. - Issue: When calling the
chatAPI, the citation list is returned first, followed by the main response content. This does not match the expected order for streaming returns. Cause: Interface parameter configuration was not adjusted, and the default logic of returning citation lists early was enabled.
How to Confirm Proper Configuration
- Submit a test request that includes due diligence fields such as credit limit and days past due. Check whether the returned results include matching traceability information such as document name, update time, and field name.
- View workflow execution logs. Confirm that the recall count and reranked return count of the knowledge base search node fall within the configured value ranges.
- Test {{}} format variable references. Observe whether parsing errors occur, and confirm that the switch to / mode for variable retrieval has been completed.
- Call the
chatAPI. Check the return timing of the citation list, and confirm that it aligns with the configured parameter logic.
