What the Data for This Category Looks Like
Collateral material data primarily comes from physical scans submitted offline by business entities, electronic documents uploaded online, and archived information from government public disclosure platforms. Updates are triggered by business processes, with only one update per corresponding material per transaction. Most documents follow fixed formats, such as guarantee letters, property ownership certificates, time deposit certificates, or public record pages of guarantee filings. Their structure includes subject identity information, guarantee target details, amount and term fields. Field units include CNY, square meters, calendar days, and other standard units. Some handwritten scanned documents contain unstructured text fragments.
What Constraints These Characteristics Impose on the Model Integration and Configuration Stage
The mixed multi-source document structure and unstructured fragment features of collateral materials require configuring file parsing parameters compatible with multiple formats such as PDF and JPG during the model integration phase. The update rhythm triggered per transaction means no incremental synchronization logic is needed. Parsing can be fixed to trigger immediately after material upload completes. Fields such as amounts and areas with clear units require configuring entity extraction rules for unit recognition, to prevent separation of numerical values and their associated units. Unstructured text fragments from handwritten scanned documents require adjusting the segment parsing length threshold, to prevent key information from being truncated.
How to Set the Configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 20 MB | Collateral materials are mostly single property certificates or correspondence documents. Single-file size typically does not exceed 20 MB, to avoid excessive consumption of storage resources. |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Collateral materials include multi-page scanned documents or long-text correspondence, with extended parsing times. 120 seconds covers most scenarios. |
maxExtractEntityLength | 800–1200 characters | Core information of collateral materials is concentrated on a single page or continuous paragraphs. This range can fully capture key fields such as guarantee amount and term. |
ENABLE_MULTI_FORMAT_PARSE | Enabled | Collateral materials include multiple formats such as PDF, JPG scanned documents, and Word documents. Enabling this setting adapts to multi-source input. |
ENTITY_UNIT_AWARE | Enabled | Collateral materials include unit fields such as CNY and square meters. Enabling this setting preserves the association between numerical values and their units. |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- A
400 Bad Requesterror code is returned when calling the model. The cause is incorrect permission configuration forOPENAI_API_KEY, or the proxy server failing to correctly forward the authentication header for model requests. - Complete model request input parameters cannot be retrieved. The cause is that the
LOG_REQUEST_PAYLOADconfiguration is not enabled, so the platform does not record complete request body content. - An error is triggered after continuous questioning when calling
o1orclaudeseries models. The cause is that the total token count of the context window is not limited, exceeding the maximum length threshold supported by the model.
How to Verify That the Configuration Is Correct
- Upload a standard guarantee letter document, check if the parsed text fully includes key fields such as guarantee amount and term. Adjust the value of
maxExtractEntityLengthbased on the results. - Trigger a model call, check if the complete request body content is recorded in the logs, to confirm whether the
LOG_REQUEST_PAYLOADconfiguration is active. - Call the target model and pass test collateral material data, verify whether the entities in the returned results include correct unit associations, to confirm whether the
ENTITY_UNIT_AWAREconfiguration is enabled. - Upload a collateral material document with a size exceeding normal business ranges, verify whether the upload is blocked, to confirm whether the
UPLOAD_FILE_MAX_SIZEconfiguration is active.
