What the data for this category looks like
Internal office documents for hazardous chemicals storage and transportation originate primarily from storage and transportation ledgers, daily inspection records, safety compliance manuals, employee training materials, and emergency response documents. Ledgers and inspection records are updated daily. Compliance documents and training materials are updated alongside business adjustments or at quarterly milestones. Document types include multi-page long PDF compliance manuals, structured table-based ledgers, and scattered work order documents. Fields include hazardous chemical identification numbers, storage locations, transportation batches, safety parameters such as flash point and explosion limit, and responsible person information. Some documents are scanned copies with handwritten annotations.
Constraints for Document Parsing and Chunking
Large compliance manuals have large individual file sizes. Sufficient time must be allocated for parsing processes to avoid mid-run interruptions. Structured table ledgers have strong field correlations. Row and column structures must be retained during chunking, otherwise the link between parameters and their associated descriptions will be lost. Safety parameters with professional units are easily truncated during chunking. Ensure values and their units remain within the same chunk. Fast parsing workflows must be used for frequently updated inspection work order documents to avoid delays that disrupt office efficiency. Scanned documents must support OCR extraction, otherwise handwritten annotations and printed content cannot be identified.
Configuration Recommendations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Meets the large-file upload requirements of hazardous chemicals compliance manuals, prevents files from being blocked due to excessive size |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long documents require sufficient parsing time, prevents parsing failures caused by overly short default timeout thresholds |
chunkSize | 800–1200 characters | Matches the paragraph length of hazardous chemicals professional documents, avoids splitting technical terms or parameter combinations |
chunkSplitter | Separate by paragraph + heading | Retains document structure, ensures compliance clauses and corresponding safety parameters stay within the same chunk of content |
customPdfParse | Enable Marker parsing | Supports OCR extraction for scanned inspection records, restores structured tables and handwritten annotation content |
chunkSettingMode | Manual configuration | Adjust chunking rules for hazardous chemicals professional fields, adapts to non-general document structures |
Three Common Configuration Mistakes
- Symptom: A file parsing tool call returns a timeout error or no valid parsing results. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. Parsing long compliance documents exceeds the default timeout threshold. - Symptom: Parsed documents lose table content or have corrupted formatting. Cause:
customPdfParsewas not enabled for Marker parsing mode. The default parsing method cannot retain structured table fields from hazardous chemicals ledgers. - Symptom: The file parsing function malfunctions after upgrading to FastGPT v4.17.0, and normal operation resumes after downgrading to an older version. Cause: The parsing plugin dependency for
customPdfParsewas not configured correctly, and the new version's container runtime parameters were not matched.
How to Verify Proper Configuration
- Upload internally stored hazardous chemicals compliance documents, confirm the parsing process has no timeout interruptions.
- Upload inspection record documents containing structured tables, confirm parsed content retains complete table structures and fields.
- Verify that chunked content does not truncate professional parameters and their associated units, such as flash point values and their corresponding units not being split across different chunks.
- Test file parsing tool calls via the conversation flow, confirm there are no call failure errors, and that returned parsed content meets expectations.
