What the data for this category looks like
The data sources for this category include work safety supervision systems, enterprise hazard self-inspection systems, law enforcement inspection records, and accident statistics systems. The update frequency is daily. Daily documents include hazard inspection lists, hazard management ledgers, rectification notices, review records, and major hazard special supervision notices. Document structures cover structured list entries, semi-structured rectification requirements, and hierarchical supervision documents. Fields include hazard level, rectification deadline, responsible entity, rectification measures, and others. Some documents are stored in Excel or PDF formats.
What constraints do these characteristics impose on the document parsing and chunking stage
Batch documents updated daily require parsing processes to have stability and scalability, to avoid task blocking caused by excessive time spent on a single document. Mixed document types require parsing tools to adapt to both structured table data and unstructured text content, to avoid field loss or semantic disconnection. Data sources deployed on internal networks, such as enterprise internal hazard self-inspection systems, may have access permission restrictions, so parsing configurations for internal network environments need to be supported. The existence of 10,000-row-level structured data and multi-page PDF documents requires chunking rules to balance content completeness and semantic relevance, to avoid overloading individual chunks.
How to set the configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to field-intensive content such as hazard lists and management ledgers, balancing single-chunk semantic completeness and retrieval efficiency |
chunkSplitter | Split by paragraph + title | Matches the hierarchical structure of rectification notices and review records, retaining contextual association between rectification requirements and responsible entities |
customPdfParse | Enable structured extraction mode | Adapts to multi-page PDF hazard inspection reports, accurately extracting the corresponding relationship between tables and text |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses parsing time for single large hazard management ledger PDFs, avoiding timeout failures in batch tasks |
chunkSettingMode | Manual configuration | For Excel-format inspection lists, chunking rules can be individually adjusted to adapt to 10,000-row-level structured data |
Three common mistakes
- Symptom: Internal network Confluence pages fail to be parsed, returning empty results or parsing failure prompts. Cause: The internal network access permission configuration is not adapted, or the parsing timeout parameter is not adjusted, preventing the pulling of document content from internal network systems.
- Symptom: Parsing a PDF-format hazard management ledger with more than 500 pages triggers a timeout error or returns incomplete parsing results. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted to a value suitable for large documents, and the parsing time for a single document exceeds the default threshold. - Symptom: After parsing an Excel-format hazard inspection list, the large model prompts an incomplete request, or chunked content contains too many irrelevant fields. Cause: The
chunkSizeparameter is not adjusted for structured Excel data, and a single chunk contains tens of thousands of rows of data, leading to failed semantic association and reduced retrieval efficiency.
How to confirm that the configuration is complete
- Upload a hazard inspection list document exported from an internal network system, and check whether the parsing result contains complete hazard entries and rectification requirements.
- Upload a single PDF-format management ledger with more than 500 pages, and confirm that the parsing task completes within 10 minutes with no timeout errors.
- Upload an Excel inspection list containing more than 10,000 rows of data, and check whether the character count of each chunk in the chunking result falls within the preset range.
- After enabling the
customPdfParseparameter, check whether the table data in the PDF is correctly extracted as structured entries.
