What the Data for This Category Looks Like
E-commerce service financing daily report data primarily comes from financing application and disbursement systems on the merchant side of e-commerce platforms, payment settlement flow interfaces, and reconciliation data from cooperating supply chain financial institutions. Data is updated via batch sync of the previous calendar day’s financing details every early morning. Each daily report document includes fields such as merchant unique identifier, approved financing amount on the day, received amount, repayment deadline, annualized financing rate, and number of associated transaction orders. Amount unit is Renminbi yuan, rate unit is percentage, and order count is a positive integer.
Constraints for Knowledge Base Retrieval and Recall
High-frequency daily updates require the knowledge base incremental sync cycle to match the daily report generation rhythm, to avoid recalling expired data. The multi-field structure requires retrieval to support precise filtering by fields such as merchant ID, rate range, and repayment date, to prevent irrelevant results from being included. Fields with clear units require retrieval matching to associate and validate field units, to avoid matching failures caused by inconsistent units. The batch detailed data structure requires controlling the information volume of single retrieved results, to avoid overly long single results that harm reading experience.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Adapts to the text length of single merchant details in financing daily reports, avoids splitting that breaks field associations |
recall_top_k | Top 10 entries | Covers the typical number range of cooperating merchants per day, ensures complete core retrieval results |
similarity_threshold | 0.75–0.85 | Balances precision and recall rate, adapts to the precise matching requirements of multi-field scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the parsing time of batch daily report documents, avoids timeout during single batch parsing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to the upload volume of batch daily report files, supports batch import of full daily data for a single day |
enable_field_extraction | Enabled | Extracts fields such as merchant ID and financing amount, supports subsequent field-level retrieval filtering |
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 case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: Retrieval operates normally during debug preview, but returns empty or no matching content after deployment to a custom page. Cause: API call permissions for the page are not configured correctly, or the correct knowledge base identifier is not included in retrieval parameters.
- Symptom: Fields are parsed as empty after importing daily report files in Markdown format. Cause: Field extraction configuration is not enabled, or the table structure of the Markdown document does not match preset field parsing rules.
- Symptom: All financing daily report images imported to the cloud version of the knowledge base show loading errors. Cause: Cross-domain access permissions for image resources are not configured, or image link validity periods are too short to allow normal reading.
How to Confirm Proper Configuration
- Run a parsing test for a single daily report document, check if the parsed fields match the structure of the original document.
- Submit a retrieval request based on a specified merchant identifier, verify that returned results only include data related to the target merchant.
- Trigger the knowledge base incremental sync task, wait for sync completion, then retrieve that day's data to confirm the latest content has been included in the retrieval scope.
- Call the retrieval interface, verify that the number of returned results matches the preset recall count configuration.
