What the Data for This Category Looks Like
Data for this category comes from the full-process electronic enterprise registration system, the National Enterprise Credit Information Publicity System, the Electronic Business License System, and the residence information database, with a daily update frequency. Commonly processed documents include establishment registration applications, articles of association, shareholder resolutions, residence certificates, business licenses, food business license applications, and more. Most documents are standardized forms or structured text, containing fixed fields such as unified social credit code, residence, business scope, and shareholder information. Some documents are scanned copies or formatted PDF files.
What Constraints These Characteristics Impose on the "Document Parsing and Chunking" Link
Standardized forms have concentrated and strongly correlated fields. Document parsing and chunking must avoid splitting critical business field combinations, such as the voting content and signature of a shareholder resolution, or the name and residence information of an establishment registration application. Daily updated data sources require the parsing process to have low latency, and the timeout threshold must be strictly controlled. Mixed input of scanned copies and formatted PDFs requires adaptation to multi-format parsing capabilities, while retaining the logical correlation between fields. The length span of different documents varies widely, from single-page residence certificates to dozens of pages of articles of association. Chunking parameters must be flexibly adjusted to accommodate different content volumes.
How to Set the Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the field combination length of documents in this category, avoiding splitting critical business blocks such as shareholder information and business scope |
chunkSplitter | Split by paragraph + title | Matches the structure of standardized forms, retaining field correlation within the same paragraph |
customPdfParse | Enabled | Adapts to mixed input of scanned copies and formatted PDFs, improving the accuracy of structured content extraction |
UPLOAD_FILE_MAX_SIZE | 100 MB | Covers the upload requirements of large-volume documents such as dozens of pages of articles of association, preventing interception due to oversized files |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to daily updated batch parsing scenarios, preventing parsing timeouts for large or complex documents |
chunkSettingMode | Manual configuration | Flexibly adjust chunking parameters for different document types, meeting differentiated needs for standardized forms and long texts |

Three Common Mistakes
- Phenomenon: An error is returned after uploading a file input address after enabling the document parsing tool in the workflow. Cause: The
customPdfParseparameter is not configured correctly, orUPLOAD_FILE_MAX_SIZEis not adjusted to a value suitable for the file volume, causing the parsing process to fail to read the file normally. - Phenomenon: Some PDF files cannot be recognized, and the extracted content is empty or key fields are missing. Cause:
customPdfParseis not enabled, or thechunkSizeparameter is set too small, splitting the fixed form field combinations within the PDF. - Phenomenon: Timeout errors occur when parsing multiple documents in batch. Cause: The value set for
PARSE_FILE_TIMEOUT_SECONDSis too low, not adapting to the batch document parsing requirements for daily updated data in this category.
How to Confirm the Configuration Is Correct
- Upload two types of documents: single-page residence certificate and dozens of pages of articles of association, verify that the parsed chunk results do not split critical business fields, such as the complete content of a shareholder resolution.
- After configuring
PARSE_FILE_TIMEOUT_SECONDS, upload the target document with the maximum volume, verify that the parsing process does not trigger a timeout error. - Check the enabled status of
customPdfParse, upload a scanned PDF, verify that structured fields such as the unified social credit code are correctly extracted. - Check the configuration value of
UPLOAD_FILE_MAX_SIZE, upload a document close to this threshold, verify that the upload process is not intercepted.
