What This Category of Data Looks Like
Data sources for this category include the low-income population dynamic monitoring platform, resident family economic status verification system, and cross-departmental shared data from public security, human resources and social security, medical insurance, housing and urban-rural development, and tax authorities. Update frequency is monthly.
Daily documents include minimum living security application forms, family economic status verification reports, household investigation forms, democratic appraisal records, public notice materials, and assistance approval forms. Data fields focus on family economic status, member relationships, and assistance eligibility. Some documents are non-editable PDFs scanned after offline completion, some are structured Excel files, with no unified standard formatting.
Constraints Imposed on Document Parsing and Chunking
Monthly batch-updated data requires the parsing process to support batch task processing, to avoid timeouts caused by loading excessive data in a single run. Mixed structured data from cross-departmental sharing and unstructured offline-scanned documents requires parsing logic adapted to different formats.
Fields related to family economic status have strong interconnections. Chunking must retain context association between fields to avoid losing complete information required for eligibility judgment after splitting. Offline-scanned documents may have messy formatting, missing characters, and other issues. Basic OCR parsing adaptation is required to ensure accurate extraction of core fields.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Covers core information blocks of single documents such as family economic status verification reports and household investigation forms, retains association between fields |
chunkSplitter | Split by paragraph + semantics | Adapts to mixed-format documents, avoids breaking the complete logic of democratic appraisal records and public notice materials |
customPdfParse | Enable OCR adaptation | Handles non-editable PDFs such as offline-scanned minimum living security application forms and household investigation forms, ensures accuracy of text extraction |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the processing duration of monthly batch data import, avoids timeout during parsing of large verification reports |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports batch import of summary data files shared across departments, meets the batch requirements of monthly updates |
chunkSettingMode | Manual configuration | Customizes chunking rules based on the field characteristics of documents in this category, adapts to the requirement of retaining context related to family economic status |
Three Common Misconfigurations
- Phenomenon: After uploading an Excel-format family economic status verification report, the data processing section shows empty. Cause: Excel structured parsing configuration is not enabled, or file column fields do not match system preset rules.
- Phenomenon: Parsing tasks time out and fail during batch import of monthly summary data. Cause: The
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is set too low, not adapted to the overall processing duration of batch data. - Phenomenon: Vectorization processing speed is slow. Cause:
chunkSizeis set too large, or batch parsing queue is not enabled, leading to excessive load on single-task processing.
How to Verify Proper Configuration
- Upload a single minimum living security application form PDF, check if the parsed text blocks retain complete context of applicant information and family income fields.
- Batch import monthly summary Excel data, confirm that there are no empty field errors in the data processing section, and that the number of imported records matches the actual count.
- Adjust the
chunkSizeconfiguration, test whether the length of chunked text meets the information density requirements of business documents. - Trigger a parsing task, confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration does not trigger a timeout error.
