What the data for this category looks like
Commercial property financing daily report data comes from operational ledgers of commercial property projects, financing filing public notices from local district business management committees, and daily loan notices from cooperating financial institutions. Data updates on a T+1 daily schedule. This means the report released the next day covers financing records from the current day. Documents are presented as structured tables. Each page contains one or more financing records. Fields include project ID, project name, financing subject, single financing amount, fund provider name, loan date, and filing number. Financing amount is denominated in ten thousand RMB. Loan date and filing number are unique identification fields.
Constraints imposed by these characteristics on citation sources and traceability
The multi-source, dispersed nature of commercial property financing daily reports requires configuring field alignment rules for multiple data sources. This prevents traceability matching failures caused by differing field names across sources. The daily T+1 update schedule requires configuring scheduled sync tasks that match the update frequency. This ensures retrieved data is the latest daily financing records. The structured document format requires enabling structured parsing configuration. This ensures the system can accurately extract unique identification fields like filing numbers. Fuzzy text matching cannot achieve this result. Fields include clear amount units, so unit normalization rules must be configured. This unifies financing amount descriptions across sources. It avoids incorrect associations during traceability caused by unit inconsistencies.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_STRUCTURED_DATA | Enabled | Commercial property financing daily reports are structured table documents. Enabling this setting automatically extracts table headers and field metadata, providing an accurate matching foundation for traceability |
SOURCE_MATCH_KEY | filing number | Every financing record has a unique filing number. Using this as the matching key avoids duplicate or incorrectly associated traceability results |
| Number of Recalled Entries | 8-12 | Single financing records have multiple fields. This value range balances recall coverage and context redundancy |
| Similarity Threshold | 0.75-0.85 | Structured data has high field matching accuracy. This interval filters low-relevance recall results and retains valid matching items |
| Number of Reranked Returned Entries | 3-5 | Final displayed traceability sources must be concise. Prioritize financing records most relevant to the current query |
SYNC_FREQUENCY | Every 24 hours | Matches the daily T+1 update schedule of commercial property financing daily reports, ensuring data source timeliness |
The parameter values provided on this page are common recommended 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 adjusting the number of recalled entries to 2000, the large language model generates content without any citation references, and logs show normal recall results. Cause: The number of reranked returned entries configuration is not set. The large volume of redundant data retrieved by the system exceeds the context window, making it impossible to filter valid traceability sources.
- Phenomenon: When generating content via external API calls, no preset traceability fields are returned, while local testing processes work normally. Cause: The return traceability metadata switch is not enabled in the release channel. External calls only return plain text results and do not carry structured traceability information.
- Phenomenon: Some financing records cannot be correctly traced, and the displayed source does not match the actual query content. Cause:
SOURCE_MATCH_KEYis not set tofiling number. The system uses fuzzy text matching, leading to incorrect associations.
How to confirm configurations are correctly set
- Upload a structured commercial property financing daily report document. Check if the preset fields are correctly extracted in the parsing results. Confirm that fields such as filing number and financing amount are accurately identified.
- Submit a query targeting a single financing record. Check if the generated content includes traceability information matching that record. Verify that traceability fields match the fields in the document.
- Call the external API interface. Check if the returned results include traceability metadata fields. Confirm that the field names match the configured
SOURCE_MATCH_KEY. - Modify the value of the number of recalled entries. Observe if the number of traceability sources attached to the generated content matches the adjusted expectation.
