What This Type of Data Looks Like
Documents for policy and regulatory basis in the basic chemical industry originate from industry regulatory documents, mandatory standards, and normative official releases issued by relevant national authorities. Document updates align with official policy release timelines. Most are formal PDF official documents, containing document numbers, issuing units, effective dates, and chapter and clause structured formats. Core document fields cover compliance indicators, production capacity limits, unit energy consumption, safety protection requirements, and more. Common units include tons, cubic meters, kilograms, ten thousand yuan per ton, and similar.
What Constraints Do These Characteristics Impose on the "Document Parsing and Chunking" Link
The characteristics of basic chemical industry policy documents create three core constraints for document parsing and chunking. First, most formal official documents include headers, footers, page numbers, and document number bars. Parsing workflows must filter redundant non-body content to avoid disrupting subsequent chunking logic. Second, the structured format divided by clauses and chapters requires chunking operations to align with clause boundaries, preventing splitting of a single complete compliance requirement. Third, documents contain quantitative indicators with industry-specific units and tabular data. Chunking must retain the contextual binding of indicators and units, while supporting full extraction of tabular content to avoid semantic breaks and data loss.
How to Configure the Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
customPdfParse | Enabled | Most basic chemical industry policy documents are formal PDFs with headers and footers. Enabling custom PDF parsing filters redundant non-body content and adapts to structured official document formats |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single policy documents are mostly formal documents ranging from tens to hundreds of MB. Setting 1000 MB covers most bulk upload scenarios and prevents file blocking |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | For long documents or bulk parsing scenarios, 600 seconds covers the complete parsing process and prevents parsing failure due to timeout |
chunkSize | 800–1200 characters | Basic chemical industry policy clauses are mostly long sentences containing quantitative indicators. A chunk length of 800–1200 characters retains complete semantic units and avoids splitting key compliance requirements |
chunkSplitter | Split by paragraph and clause | Documents have a structured format divided by chapters and clauses. Splitting by paragraph and clause matches the original document structure and improves the accuracy of subsequent Q&A context |
chunkSettingMode | Manual configuration | Adjusting chunking parameters for the structured characteristics of chemical policy documents is required. Manual configuration allows flexible adaptation to policy documents of different formats |
Three Common Misconfigurations
- Symptom: After uploading a policy document containing production capacity statistics tables, the parsing result has empty table fields or missing data. Cause: Custom parsing configuration is not enabled. The default parsing logic does not fully extract structured data within tables.
- Symptom: After uploading a single large policy document, the interface shows parsing timeout. Restarting the server does not resolve the issue. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default timeout duration is insufficient for parsing long documents. - Symptom: Chunking results show concatenated content across clauses, leading to failure to match complete compliance requirements during Q&A. Cause: The
chunkSplitteris not set to split by clause. The default character-length-based splitting causes semantic breaks.
How to Verify Successful Configuration
- Upload a basic chemical industry policy document with headers and footers. Check whether the parsing result removes non-body headers and footers, confirming the custom PDF parsing configuration is active.
- Upload a policy document of large volume. Confirm the upload process is not blocked, and the maximum upload file size configuration fits business needs.
- Parse a policy document with multiple clauses. Check whether chunking results are divided according to the original document clauses, confirming the chunking splitting rule matches the document structure.
- Upload a policy file containing structured tables. Check whether the parsing result fully retains table fields and data, confirming the table parsing configuration is active.
