What data for this category looks like
State-owned capital operation companies' policy and regulatory basis data mainly comes from regulatory rules issued by state-owned asset supervision and administration institutions, internal corporate governance documents, and annual operational compliance reports. Updates are carried out irregularly in line with adjustments to regulatory policies and revisions of internal systems. Most documents are in official document format, including document numbers, chapter hierarchies, nested tables and attachments. Common formats are Word, PDF and Excel. Fields include document number, issuing entity, effective date, clause content, etc. There is no unified fixed unit; actual needs are matched based on specific document content.
What constraints do these characteristics impose on the "document parsing and chunking" link
The nested structure of official documents requires retaining chapter hierarchies and table integrity during parsing, to avoid splitting that breaks semantic connections. Large Word files with multi-chapter nesting and long paragraphs will lengthen parsing time, so chunking logic needs to be optimized to adapt to long documents. Excel-format policy lists mostly follow the structure of one policy per row. If automatic chunking fails to recognize row separators, multiple policies will be merged into the same chunk. Irregularly updated document version differences require the parsing process to be compatible with field arrangements of old and new formats, to avoid parsing errors caused by format changes.
How to configure the settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the semantic length of single policy clauses in state-owned capital operation policy documents, avoiding splitting that breaks complete compliance statements |
chunkSplitter | Split by paragraph + chapter hierarchy | Matches the chapter, section and clause hierarchy structure of policy documents, retains semantic unit integrity, and adapts to nested tables and long paragraph content |
customPdfParse | Enabled | Preserves the original typesetting and table structure of PDF-format policy documents, avoiding content disorder after parsing |
UPLOAD_FILE_MAX_SIZE | 15 MB | Adapts to the common size of policy documents around 10 MB, avoiding upload timeouts or parsing interruptions |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses the parsing time required for large Word files and nested tables, reserving sufficient processing time |
chunkSettingMode | Manual configuration | For Excel-format policy lists, row separation can be set separately, adapting to the document structure of one policy per row |
Three common mistakes
- Phenomenon: After uploading a Word policy document of around 10 MB, the parsing progress stalls for a long time or triggers a timeout error. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout duration is insufficient to process large documents with nested multi-chapters. - Phenomenon: After importing an Excel-format policy list, the automatic splitting result merges multiple policy rows into one chunk. Cause: The
chunkSettingModeis not switched to manual configuration and row separation is not specified. The default chunking logic does not recognize the semantic boundary of Excel single rows. - Phenomenon: A precise question about a certain policy clause fails to recall the corresponding chunk, but works normally after creating a new knowledge base. Cause:
customPdfParsewas not enabled during the first import or thechunkSplitterconfiguration is incorrect, resulting in the loss of key document numbers and effective date fields in the chunks, leading to semantic mismatch during matching.
How to confirm the configurations are set correctly
- Upload a single large document that matches the category characteristics, check that no timeout prompt appears during the parsing process, to verify that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration takes effect. - Import an Excel-format policy list, preview the chunk preview interface, confirm that each policy entry corresponds to an independent chunk, to verify the configuration effect of
chunkSettingModeandchunkSplitter. - Select precise clause content from the document as a test question, confirm that the corresponding chunk is recalled normally, to verify the semantic integrity of the chunks.
- View the parsed document structure, confirm that nested tables and chapter hierarchies are not damaged, to verify the configuration effect of
customPdfParse.
