What this category of data looks like
The data sources for building construction project financing daily reports mainly include public project financing filing documents from housing and urban-rural development authorities, desensitized financing ledgers from partner banks, and project-disclosed engineering fund allocation vouchers. Data is updated daily, covering changes such as newly added financing receipts and credit limit adjustments on the current day. Document formats are primarily structured Excel and CSV, with a small number of scanned PDF reports. Core fields include project unique identifier, financing entity name, credit granting bank name, single financing amount, fund receipt date, and corresponding project node. The amount unit is uniformly ten thousand yuan, and dates are accurate to the calendar day.
What constraints these characteristics impose on the "citation sources and traceability" link
Since data sources are scattered and include both public and desensitized private data, the traceability link must distinguish permission verification rules for different data sources to avoid sensitive information leaks. The daily update feature requires filtering expired data by timestamp during traceability, to ensure cited content is the latest daily report information. Multiple document formats require separate configuration of structured extraction and unstructured parsing rules, to ensure original data from different formats can be accurately located. The project-centric field design requires binding the project unique identifier during traceability, rather than only binding keywords, to avoid confusion of financing data from different projects.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | Top 8-12 entries | Building construction project financing daily reports contain multiple sets of project data per daily report. Excessive recall increases context redundancy, while insufficient recall fails to cover core financing information |
similarity_threshold | 0.75-0.85 | This category of data has a high degree of field standardization. An overly high threshold will miss relevant financing entries, while an overly low threshold will introduce financing data from unrelated projects |
structured_parse_enable | Enabled | Most building construction project financing daily reports use structured table formats. Enabling this setting allows accurate extraction of fields and binding of unique traceability IDs |
source_id_field | Project number | This category of data uses projects as the core association unit. Using project number as the traceability identifier avoids confusion of financing data from different projects |
parse_timeout_seconds | 600 seconds | A single document may contain financing data for multiple projects. A longer timeout ensures complete parsing of all entries |
reference_mode | Embed in body text | This category requires direct embedding of cited content in the answer body, which meets the core user demand for traceability display |
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: The API call returns status code 200 but no content field. Cause: The
enable_source_referenceconfiguration is not enabled, and structured parsing rules are not correctly configured, resulting in failure to extract valid content fragments. - Phenomenon: Garbled characters appear in cited content. Cause: OCR parsing configuration is not enabled for PDF-format financing daily reports, or parsing times out before completion, resulting in truncated content fragments.
- Phenomenon: Cited knowledge base content does not appear in the response body. Cause:
reference_modeis not configured to "Embed in body text", or recalled content does not match the user's query keywords.
How to confirm the configuration is complete
- Upload a single structured Excel file of a building construction project financing daily report, and verify whether the parsed metadata includes the project number field.
- Initiate a test query, and verify whether the returned result contains a source identifier field, with field content corresponding to the row number or page number of the original document.
- Adjust
similarity_thresholdto 0.7, initiate the same query, and observe whether the number of recalled entries changes as expected. - Simulate a POST request to call the API, and verify whether the returned JSON data contains the
contentandsource_infofields.
