What the data for this category looks like
Daily documents for this category include inspection plans, inspection target lists, inspection item checklists, on-site inspection records, rectification notices, inspection result announcements, and more. Data is mainly sourced from the random inspection and public disclosure supervision platform, enterprise credit information publicity system, industry supervision systems, and law enforcement officer directory. Data updates occur monthly. Core documents are mostly structured tables, stamped PDFs, and a small number of text files. Fields include unit name, unified social credit identifier, inspection items, law enforcement officer ID number, and more. Some documents have multi-column nested structures.
What constraints these characteristics impose on document parsing and chunking
The monthly update frequency requires full data synchronization on a regular basis, and the stability of batch upload parsing must be ensured. Mixed uploads of multiple document types require the parsing module to adapt to both structured tables and formatted PDFs. For Excel documents such as multi-column nested inspection target lists, the issue where default parsing only extracts the first two columns must be avoided. Long text from on-site inspection records and itemized inspection items require chunking that balances semantic completeness and retrieval accuracy, avoiding splitting content linked to the supervision workflow.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the item length and semantic association of documents in this category, avoids splitting the association between inspection items and corresponding targets due to too-small chunks, or reducing retrieval recall accuracy due to too-large chunks |
customPdfParse | Enabled | Adapts to stamped PDF documents such as on-site inspection records and rectification notices, retains original field structure and format information, and can call built-in enhanced parsing capabilities |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Addresses single-file parsing time when uploading batch inspection plan PDFs, avoids parsing failure due to timeout |
UPLOAD_FILE_MAX_SIZE | 100 MB | Adapts to the maximum size of documents such as batch-uploaded inspection plans and target lists in this category, avoids upload failure |
chunkSplitter | Chunk by paragraph + semantics | Adapts to itemized inspection item checklists and long-text on-site inspection records, ensures semantic completeness after chunking |
chunkSettingMode | Custom mode | Configures parsing rules separately for multi-column Excel documents, avoids the issue of default parsing only recognizing two columns |
Three common mistakes
- After uploading a multi-column inspection target list Excel, the knowledge base only extracts the first two columns of content. The cause is that custom column parsing configuration is not enabled, and the default parsing logic only recognizes the preset question-answer column structure.
- When testing party building Q&A retrieval, specified inspection item content cannot be recalled. The cause is that
chunkSizeis set too large, causing inspection items to be split into different chunks and unable to form a complete semantic unit. - Parsing timeout errors occur when uploading batch PDF documents. The cause is that
PARSE_FILE_TIMEOUT_SECONDSis not adjusted to a reasonable range, and the default timeout threshold is insufficient to support complete parsing of stamped PDFs.
How to confirm the configuration is correct
- Upload a single multi-column inspection target list Excel, check whether the parsed text contains all preset field content.
- Upload a single stamped on-site inspection record PDF, confirm that the parsed result retains original format information such as law enforcement officer signatures and inspection time.
- Adjust
chunkSizeto the target range, retrieve the specified inspection item, and confirm that the returned result contains complete corresponding associated content. - View the parsing task log, confirm that no format errors or timeout prompts appear, and the task status is successful.
