What the Data for This Category Looks Like
Data sources include daily interbank offered rates published by the National Interbank Funding Center, internal credit approval ledgers of urban commercial banks, daily financing business reports submitted by subordinate branches, and transaction data from the People's Bank of China's large-value payment system. Updates follow a daily schedule. Same-day data is generated the following morning. Document structure centers on structured tables, with a small amount of unstructured supplementary notes. Fields include: financing entity name, financing term (unit: day), financing amount (unit: ten thousand yuan), financing interest rate (unit: %), counterparty institution type, and business occurrence time.
Constraints on the Knowledge Base Retrieval and Recall Link
The structured table-centric document structure requires the retrieval link to preserve field-level semantic associations. This avoids invalid recall caused by cross-field confusion. The daily high-frequency update feature requires the knowledge base to support incremental updates. Full re-imports will otherwise consume excessive computing resources. Fields include numerical data with clear units. Retrieval must support numerical range matching, not just keyword matching. Unstructured supplementary notes are short. Segmentation strategies must be optimized to preserve complete semantics. Mixed domestic and foreign peer institution names require the retrieval model to have cross-language semantic understanding capabilities.
Configuration Setup
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 600–1000 characters | Adapts to the text length of single business records in urban commercial bank financing daily reports, avoids splitting that breaks field associations |
embeddingModel | Multilingual general embedding model | Covers cross-language semantic matching needs for domestic and foreign peer institution names, resolves low cross-language recall rates |
retrieveTopK | Top 8–12 entries | Adapts to the typical number of financing business entries for urban commercial banks on a single day, balances recall coverage and result redundancy |
similarityThreshold | 0.72–0.85 | Adapts to retrieval requirements for precision-matched business data, filters irrelevant historical data, retains highly relevant same-day business |
PARSE_TABLE_ENABLE | Enabled | Financing daily reports use structured tables as the core carrier. Enabling table parsing preserves field-level semantic associations |
UPLOAD_INCREMENTAL_ENABLE | Enabled | Adapts to the daily high-frequency update business feature, reduces repeated computing resource consumption |
The parameter values provided on this page are common recommendations used as starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Phenomenon: After calling the batch re-embedding interface, vectors for some financing daily report documents are not updated. Cause: The target knowledge base collection ID is not specified in the request, so the re-embedding operation does not apply to the exclusive dataset.
- Phenomenon: Using the 4.9.10 version interface to create a text collection, passing the
splitModeparameter asparagraphdoes not trigger paragraph-first splitting mode. Cause: The parameter is not nested within theconfigfield, so the system fails to correctly recognize the splitting mode. - Phenomenon: When calling the external file upload interface, a 400 status code is returned indicating a file format error. Cause: The
Content-Type: multipart/form-dataheader is not included in the request, so the system cannot recognize the uploaded file format.
How to Verify Proper Configuration
- Upload a single test document of the same-day financing daily report, check the parsed segmentation results, confirm that table fields are fully retained and not overly split.
- Enter typical financing business keywords, check the similarity scores of recall results, adjust
similarityThresholdto a range that meets business requirements. - Simulate daily incremental uploads of new financing daily report documents, confirm that the system only processes new documents and does not trigger full re-embedding tasks.
- Call the external upload interface to upload a test file, confirm that the file is successfully parsed and synchronized to the target knowledge base collection.
