What the data for this category looks like
The core documents for this category include minimum living security application forms, family economic status verification reports, household survey forms, democratic review records, public notice materials, and assistance approval forms. Data mainly comes from the low-income population dynamic monitoring platform, resident family economic status verification system, and cross-department shared data from public security, human resources and social security, medical insurance, housing and urban-rural development, tax authorities, and other departments. The update frequency is monthly. Documents contain structured fields and semi-structured paragraphs, organized by household. Some paper materials require scanning to complete digitization conversion.
What constraints do these characteristics impose on the "document parsing and chunking" link
Monthly batch document updates require the parsing link to support high-concurrency batch processing to avoid single parsing timeouts. Documents from cross-department sources have inconsistent formats, including scanned documents, structured Excel files, and semi-structured PDFs. Multi-format parsing logic must be adapted. The household-based field structure requires that associated information such as family members, income and property be retained during chunking to avoid splitting that breaks business context. Additionally, the rigor of minimum living security review requires that parsing results not miss core fields. Otherwise, subsequent verification and approval processes will be affected, leading to risks of incorrect or missed security assistance.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the single-paragraph field length of family economic status verification reports, avoiding splitting core associated information |
chunkSplitter | Split by paragraph + semantics | Matches the paragraph structure of household information, income details, and approval nodes in documents, retaining business logic integrity |
customPdfParse | Enable OCR mode | Adapts to a large number of paper scanned household survey forms and public notice materials, restoring text content in scanned documents |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses large-volume cross-department shared PDF documents in batches, avoiding task interruption caused by parsing timeouts |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Compatible with large-volume Excel and PDF files exported from single cross-department data |
chunkSettingMode | Manual configuration | Customizes chunking rules to match business field association requirements for the fixed document structure of this category |
Three common errors
- Batch document uploads are interrupted mid-process, and parsing cannot resume after restarting Docker. The cause is failure to adjust the
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSparameters. Large-volume documents exceed limits, or batch parsing triggers task termination due to timeout. - A timeout error is reported during private deployment of markerpdf parsing, while the parsing service shows success. The cause is that `PARSEFILETIMEOUTSECONDS` is set too short. FastGPT actively terminates parsing tasks that have not timed out, leading to abnormal task status.
- The model fails to answer questions based on the parsed document content. The cause is that core fields associated with the household are split during chunking, so complete household economic status information cannot be matched during retrieval, and the model cannot obtain valid context.
How to confirm the configuration is correct
- After deploying FastGPT v4.17.0, upload a single 100MB family economic status verification report, and check whether the parsing task is completed within the preset duration without errors.
- Export a batch of 10 monthly updated documents, and verify that the chunked content after parsing does not split information entries of the same household member.
- Select a scanned household survey form, and confirm that core fields such as family member names and income details can be extracted after OCR parsing.
- Check the system operation logs to confirm there are no parsing failure records caused by exceeding file size limits or timeouts.
