What This Category of Data Looks Like
Data for this category comes from the road transportation administration system, the national public service platform for dynamic information of road transport vehicles, and the vehicle and practitioner database. The update frequency is daily. Commonly processed documents include business license applications, vehicle technical files, driver qualification materials, safety production management systems, road transport business licenses, and more. Most documents contain structured fields and unstructured text. Some documents include attached materials related to vehicles or personnel.
Constraints on the Document Parsing and Chunking Link
The multi-system data source requires the parsing process to support export files in different formats. The daily update frequency requires the parsing process to have stable batch processing capabilities. There are various document types: structured table-style application materials, and plain text safety management systems. This requires chunking logic that adapts to different content structures. Attached materials may include vehicle photos and qualification scan files. Clear processing rules must be defined during parsing to avoid redundant content interfering with chunking results. The license handling verification link relies on accurate field extraction. Chunking must retain the integrity of key business fields to avoid field breakage after splitting.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the mixed structure of road transport documents that contain both business fields and explanatory text. Avoids overly long single chunks causing context breakage, or overly short chunks increasing retrieval overhead |
chunkSplitter | By paragraph + semantic boundary | Adapts to the structure of different document types. Retains complete table chunks for table-style materials, and splits text-style materials by semantics to avoid splitting business logic |
customPdfParse | Enabled | Adapts to PDF documents with attachments such as qualification scans and vehicle files. Retains original typesetting and attachment association relationships, and avoids redundant parsing |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Matches the time required for batch processing multiple documents updated daily. Avoids parsing timeout for large vehicle technical files |
UPLOAD_FILE_MAX_SIZE | 100 MB | Compatible with the upper limit of packaged materials for a single road transport business license application, and meets storage requirements for batch imports |
chunkSettingMode | Manual configuration | Adjust chunking parameters for different document types such as application forms and management systems to adapt to parsing needs of different links in the business handling process |
Three Common Mistakes
- Scenario: When importing road transport documents in DOC or PPT format, enabling
customPdfParsedoes not retain original images, and the parsing result only contains text. Cause:customPdfParseonly applies to PDF format documents, and no corresponding image retention rules are configured for non-PDF documents. - Scenario: When parsing Excel-format vehicle files from road transport enterprises, sheet names are not read, and only the content of the default first worksheet is obtained. Cause: The sheet recognition logic of the corresponding configuration item is not enabled, and multi-page parsing rules are not configured for structured table-style documents.
- Scenario: Parsing task timeout errors occur when batch importing multiple business license application documents. Cause: The value of
PARSE_FILE_TIMEOUT_SECONDSis set too low, and does not match the parsing time required for a single large-volume document.
How to Verify Proper Configuration
- Upload a single typical document, such as a vehicle technical file PDF, and check if the parsing result retains original images and typesetting. Confirm that the
customPdfParseconfiguration is effective. - Import an Excel-format practitioner file and check if the parsing result includes the content and names of all sheet pages. Confirm that the multi-page table parsing configuration is correct.
- Submit a batch document parsing task and monitor task duration. Confirm that the
PARSE_FILE_TIMEOUT_SECONDSsetting meets actual parsing requirements. - Split different types of documents, such as safety management system text and business license application forms, and check if the chunking result retains the integrity of business fields. Confirm that the
chunkSizeandchunkSplitterconfigurations adapt to the document structure.
