What the data for this category looks like
The data for this category originates from safety production supervision systems, enterprise hazard self-inspection systems, law enforcement inspection records, and accident statistics systems. Daily documents include hazard inspection checklists, hazard management ledgers, rectification notices, review records, and major hazard rectification supervision notices. Data is updated daily. Document structures fall into two categories: structured tables and official documents. Core fields include hazard description, rectification requirements, responsible parties, review conclusions, and other key content. Document formats vary across different sources.
What constraints do these characteristics impose on document parsing and chunking
Batch documents updated daily require the parsing process to be efficient, to avoid excessive single-file parsing time that disrupts overall progress. The mixed structure of structured tables and official documents requires chunking logic to balance table integrity and text relevance, and must not split the inspection, rectification, and review content of a single hazard into different chunks. Format differences across sources require parsing configurations to be flexible, adapting to documents in various export formats while ensuring core fields are not lost. Failure to preserve core fields will impact the complete subsequent hazard inspection and governance process.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Daily documents contain long texts such as hazard descriptions and rectification requirements. This range preserves the integrity of the rectification logic for a single hazard, and adapts to the content length of cells after table splitting |
chunkSplitter | Split by paragraph + heading | Documents contain content with different structures such as inspection checklists and rectification notices. Splitting by headings can distinguish different hazard entries, avoiding chunking across entries |
customPdfParse | Enable table recognition mode | Most daily documents contain structured tables such as hazard inspection checklists and management ledgers. Enabling this mode preserves the table row and column structure, avoiding messy content after parsing |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single files may contain multiple pages of rectification records or batch inspection checklists, so sufficient parsing time must be reserved to avoid parsing failure due to timeout |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Bulk uploaded hazard ledger files may be large in size, and this value covers upload requirements for most scenarios |
chunkSettingMode | Manual configuration | Chunking requirements differ across document types (such as supervision orders and inspection checklists). Manual configuration allows flexible adjustment of parameters to adapt to business scenarios |
Three common misconfiguration errors
- Symptom: After uploading a hazard ledger file, the parsing log continuously reports slow operation xxxxms, and parsing progress stalls. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, or thechunkSizevalue is too large, causing single-file parsing time to exceed the default threshold. - Symptom: After importing an Excel file for a hazard inspection checklist, only the first few rows of data are captured, and subsequent rows are lost. Cause: The table recognition mode of
customPdfParseis not enabled, or thechunkSplitteris configured to split by fixed characters, destroying the table's row and column structure. - Symptom: After importing a major hazard rectification supervision notice, the "supervision deadline" field is missing from the document parsing result. Cause: The
chunkSplitteris configured to split by plain text line breaks, without recognizing the document's heading hierarchy, causing the paragraph containing the key field to be incorrectly split.
How to verify correct configuration
- Upload a single hazard inspection checklist file, review the parsed text structure to confirm that table rows and columns, and heading hierarchy are not damaged.
- Review the parsing log to confirm there are no continuous slow operation errors, and parsing time meets business expectations.
- Test the chunked content to confirm that the description, rectification requirements, and responsible parties of a single hazard are not split into different chunks.
- Upload a file of the maximum allowed size, confirm that the upload and parsing processes complete normally, with no timeout errors.
