What This Category of Data Looks Like
This category of data originates from social insurance management systems, tax social insurance premium collection systems, market entity registration information, and shared public security and civil affairs data. Teams process common documents including insurance registration forms, payment base declaration forms, personnel change forms, social insurance premium verification notices, and personal benefit records. Daily updates apply to this data. Most documents are structured forms or semi-structured reports. Documents include fields such as the entity’s unified social credit code, personnel ID number, payment base, verified payment amount, personnel change status, and units like yuan, person, and payment month.
Constraints on Document Parsing and Chunking
Multiple system sources create large format differences across documents. Some social insurance system forms use fixed templates. Some tax system reports use dynamic layouts. Parsing tools must adapt to multiple structured document structures. Daily data volume grows with the number of insured persons. Parsing processes must maintain batch processing efficiency. Core fields such as identity information and payment base link to insurance benefits. Chunking logic must retain the binding relationship between fields and their corresponding forms. Splitting must not erase contextual associations. For semi-structured reports, headers bind to data rows. Chunking logic must first identify header groups. Processes must avoid splitting cross-page headers and data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Most documents in this category are semi-structured forms. Each chunk must cover a complete personnel information group or payment verification item to avoid splitting core associated fields |
chunkSplitter | Split by header groups | Documents include sections such as personnel change and payment verification with fixed headers. Splitting by header groups preserves data context and avoids confusion across field groups |
customPdfParse | Enabled | The official built-in parser has limited adaptability to fixed templates for social insurance forms. A custom parsing service can be configured to specifically identify form fields |
PARSE_FILE_TIMEOUT_SECONDS | 60–90 seconds | A single social insurance verification notice includes multi-page personnel data. Parsing must complete multi-page header matching and field extraction. The timeout must cover delays for batch processing |
UPLOAD_FILE_MAX_SIZE | 50–100 MB | Summary files for batch personnel change forms can reach large sizes. This range meets daily batch upload requirements |
chunkSettingMode | Manual configuration | Documents in this category have fixed structures with local variations. Manual configuration allows precise adjustment of chunking logic to adapt to different form types |
Three Common Misconfiguration Issues
- Issue: Uploading a social insurance verification PDF returns a parse failure with status code 504. Cause:
customPdfParseis not enabled, and the official built-in parser timeout is too short to complete field matching for multi-page forms. - Issue: Personnel information and payment base are separated after chunking. Cause:
chunkSplitteris configured to split by character count, not by header groups. This leads to loss of cross-field contextual association. - Issue: An insurance registration file exceeding the set size is blocked during upload. Cause: The
UPLOAD_FILE_MAX_SIZEconfiguration value is lower than the actual file size, and does not accommodate summary files for batch forms.
How to Verify Proper Configuration
- Upload a standard single insurance registration form. Review the parsed chunk results. Confirm that each chunk contains complete personnel information and corresponding payment verification items.
- Adjust
PARSE_FILE_TIMEOUT_SECONDSto a test value. Upload a multi-page personnel change form. Observe whether the parsing process times out. Adjust the value to match the processing duration required for business documents. - Upload a batch summary of social insurance premium verification notices. Check whether the file is blocked by
UPLOAD_FILE_MAX_SIZE. Confirm that the configuration value covers the maximum daily upload file size. - Switch
chunkSettingModebetween automatic configuration and manual configuration. Compare chunking results. Confirm that manual configuration adapts to the special structure of forms in this category.
The values listed above are common starting points. They should be evaluated against samples from the specific deployment.
