What the data for this category looks like
Typical service entities for this category include civil affairs bureau assistance sections, subdistrict and township civil affairs offices, community committees, and verification centers. Daily processed documents include minimum living security application forms, family economic status verification reports, household survey records, democratic appraisal records, public notice materials, assistance approval forms, and more. Data mainly comes from low-income population dynamic monitoring platforms, resident family economic status verification systems, 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. Update frequency is monthly. Core fields include family income, property status, member relationships, assistance eligibility, and so on. There are no unified fixed units; adjustments are needed based on actual verification content.
What constraints these characteristics impose on the document parsing and chunking link
Cross-department shared data comes in diverse formats, including structured forms, unstructured text, and mixed-format files. Chunking logic must balance structural integrity and semantic coherence. Monthly updated summary files have large file sizes, so adaptation to longer parsing durations is required. Core fields such as family income and member relationships directly relate to assistance eligibility. Key information must not be lost during chunking. Long text content such as household survey records is abundant. Chunk length must balance information integrity and retrieval efficiency. Avoid overly fragmented chunks that cause retrieval redundancy, or overly long chunks that lead to semantic disconnection. Error consequences directly relate to incorrect or missed security reviews, fund recovery, or public complaints. Accuracy of parsing and chunking must be ensured.
How to set configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the field length of mixed-format documents such as minimum living security application forms and household survey records, preventing key information such as family income and member relationships from being truncated |
chunkSplitter | Chunk by paragraph + semantic meaning | Compatible with mixed formats of structured forms and unstructured text, ensuring complete business logic units are retained within each chunk |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of monthly cross-department summary files, preventing parsing interruptions for large data files |
customPdfParse | Enabled | Accurately extracts structured fields for fixed-format PDF documents such as minimum living security application forms, improving parsing accuracy |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Accommodates monthly cross-department shared summary data files, meeting batch processing requirements |
Three common mistakes
- Phenomenon: The error "Cannot redefine property: toString" appears in the console after starting knowledge base indexing. Cause: A custom parsing script repeatedly defines the toString property, which conflicts with the built-in FastGPT logic.
- Phenomenon: The number of chunks generated after parsing a single family economic status verification report exceeds 3000, and indexing cannot be completed. Cause: The
chunkSizesetting is too small, failing to adapt to the long paragraphs of household survey records in the material.
Reference only; verify against the target FastGPT release and deployment documentation.
How to confirm configurations are properly set
- Upload a typical family economic status verification report, check the number of parsed chunks, and confirm it falls within the preset range.
- Check the parsing logs to confirm there are no errors related to duplicate property definitions, and verify the compatibility of the custom parsing script.
- Test uploading a monthly summary file of the maximum allowed size, and confirm parsing completes within the preset duration of
PARSE_FILE_TIMEOUT_SECONDS. - Randomly select 3 to 5 chunk contents, and confirm that key fields such as family income and member relationships are not truncated or lost.
