What the data for this category looks like
Business data for this category primarily comes from the real estate registration information system, cadastral survey database, housing transaction online signing system, tax system, and electronic certificate repository. The update frequency is daily. Commonly processed documents include registration applications, ownership certificates, survey results, tax payment vouchers, real property right certificates, and registers. Most documents are structured forms or certificate documents with fixed fields. Fields cover right subject, location, right type, area, and some files include electronic signatures and QR code identifiers.
Constraints Imposed on Document Parsing and Chunking by These Characteristics
Multiple synchronized business systems create format diversity. Data includes both structured forms and unstructured scanned documents and electronic certificates. Parsing logic must adapt to different formats. Daily updated business data requires stable and efficient parsing processes. Delays must be avoided to prevent disruption to business workflows. Documents with fixed field structures require that key information is not split during chunking. Core fields such as right holder and location must retain full context. Long registers and survey result documents require retaining the association between adjacent paragraphs during chunking. This avoids semantic breaks after splitting. Non-content elements such as signatures and QR codes on electronic certificates must be filtered during parsing. They must not be included in chunking materials.
Configuration Settings
This configuration is developed for FastGPT v4.17.0, and adapts to the document parsing and chunking needs of the real estate registration party building learning Q&A scenario.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the information density per chunk of real estate registration documents, and avoids splitting core fields or long paragraphs |
chunkSplitter | Split by semantic paragraphs | Matches the fixed format of registration documents, and retains the association logic between fields |
customPdfParse | Enable certificate-specific parsing mode | Adapts to PDF files with electronic signatures such as real property right certificates and registers, and filters non-content elements |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Covers the upload needs of large-volume documents such as survey results and registers |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses parsing time consumption for complex documents spliced from multiple systems, and avoids timeout failures |
chunkSettingMode | Manual configuration | Adapts to different types of registration documents, and allows flexible adjustment of chunking parameters |
Three Common Misconfigurations
- Phenomenon: When uploading a full register or large survey result file, the interface displays a parsing timeout and request failure. Reason: The
PARSE_FILE_TIMEOUT_SECONDSvalue is not adjusted to fit large documents. The default duration is insufficient to complete complex file parsing. - Phenomenon: After uploading an Excel-format tax payment voucher or registration application template, the parsed fields are empty or data is incomplete. Reason: The corresponding structured document parsing mode is not enabled, and the Excel table structure splitting logic is not adapted. This leads to incorrect merging or omission of table data.
- Phenomenon: When uploading a scanned copy of a real property right certificate with an electronic signature, the parsing result includes irrelevant elements such as signatures and QR codes. Reason:
customPdfParseis not configured to the certificate-specific mode. The default parsing logic does not filter non-content identifiers on electronic certificates.
How to Verify Proper Configuration
- Upload a single typical document (such as a scanned copy of a real property right certificate) and check if the parsed result retains all core fields with no irrelevant elements remaining.
- Upload a large-volume document (such as a full register) and confirm that the parsing process does not trigger a timeout error, and the time consumption meets business expectations.
- Upload an Excel-format registration application template and check if the parsed data is fully split with no field loss.
- Adjust the
chunkSizeparameter and verify that the chunking result does not split adjacent core information paragraphs.
