What the data for this category looks like
Data sources for joint-stock bank financing daily reports include official disclosed daily financing ledgers, publicly traded data from the National Interbank Funding Center, and daily financing details exported from the internal credit approval system. Data updates daily at midnight, with full data for the previous calendar day refreshed. Single daily report document sizes range from 500KB to 2MB. The document structure includes seven core fields: full financing entity name, financing amount, financing term, financing cost, fund usage, disclosure date, and submission channel. All field values follow internal bank standardization specifications.
What constraints these characteristics impose on citation source and traceability workflows
Data sources fall into two categories: internal systems and public markets. Separate permission verification and link validity check rules must be configured for each category. The daily T+1 update rhythm requires limiting the traceability time range to the previous calendar day, to avoid retrieving expired or undisclosed data. Fixed core fields require binding traceability identifiers to the full financing entity name and disclosure date, to ensure precise matching between traceability results and the original document. The fixed document size range requires adjusting parsing chunk thresholds, to avoid parsing failures that cause missing traceability results. Internal system data must connect to the bank’s internal permission system, and caller access permissions must be verified during traceability.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
source_match_field | ["Full Financing Subject Name", "Disclosure Date"] | Matches core document fields to ensure precise correspondence between traceability results and original content |
date_range_filter | ["Top 1日", "当日"] | Adapts to the T+1 update rhythm, only retrieves data within the corresponding time interval |
internal_data_auth | Enabled | Connects to the bank’s internal credit system to verify caller permissions and avoid unauthorized data traceability |
text_chunk_size | 800-1200 characters | Adapts to the 500KB-2MB document size, avoids parsing failures caused by overly fragmented or oversized chunks |
recall_top_k | Top 3 | Controls the number of retrieved results to avoid redundant information interfering with traceability accuracy |
parse_timeout | 300 seconds | Adapts to the parsing duration of single documents, avoids missing traceability results due to large document parsing timeouts |
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. Each scenario requires specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Issue: Calls to the traceability API return source links that cannot directly jump to the original document, or show 404 errors. Cause: The
source_link_validateparameter is not configured, and public data source link validity is not verified, leading to expired or invalid reference links. - Issue: Traceability results include non-current-day financing data. Cause: The
date_range_filterparameter is not set, or the time range configuration is incorrect, resulting in retrieval of cross-day historical data. - Issue: Attempting to use custom variables as matching items when configuring
source_match_fieldcauses configuration save failure. Cause: The fixed field matching rule is not followed, and an undefined variable is incorrectly used as the matching identifier.
How to Verify Successful Configuration
- Manually upload a current-day joint-stock bank financing daily report document, trigger RAG retrieval, and check if returned traceability results include the correct financing entity name and disclosure date.
- Call the traceability API with specified financing entity name and disclosure date parameters, and check if returned source links are valid and point to the original document.
- Disable the
internal_data_authparameter, attempt to call internal data sources without authorization, and check if a permission verification failure prompt is triggered. - Adjust the time range of
date_range_filter, and check if retrieval results update in line with configuration changes.
