What the data for this category looks like
Data primarily comes from internal party building management systems of state-owned coal transportation and sales enterprises, official documents issued by party committees, branch study records, and party building learning courses customized in line with transportation and sales compliance requirements. Update cadence is monthly additions of daily learning materials and quarterly updates of compliance-related party building documents. Most documents are official PDFs, PPT courses, and structured records, including fields such as issuing unit, document number, study theme, and associated transportation and sales business clauses. Some documents contain embedded transportation and sales data tables and process diagrams.
What Constraints These Characteristics Impose on Document Parsing and Chunking
Fixed official document formats for party building documents require automatic exclusion of irrelevant content such as headers and footers during parsing, to avoid mixing redundant information into chunks. For documents with embedded transportation and sales business data tables, the complete table structure must be retained to avoid splitting policy and business association content in cells. For paragraphs associated with transportation and sales compliance clauses, contextual association must be preserved to ensure that the corresponding relationship between party building requirements and transportation and sales business can be fully conveyed after chunking. Monthly updated documents in different formats must support parsing of multiple types such as PDF and PPT, and the chunking logic must adapt to differences in paragraph density across different documents.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 1000–1200 characters | Party building documents are mostly long paragraphs with embedded transportation and sales business clauses. This range can retain the complete association between a single policy and business, avoiding splitting that disrupts logical integrity |
chunkSplitter | By paragraph + semantic boundary | Adapts to the paragraph structure of official documents, while combining semantic association for splitting, to avoid separating associated content of party building themes and transportation and sales compliance |
customPdfParse | Enabled | Most coal transportation and sales party building documents contain embedded tables and process diagrams. Enabling custom PDF parsing can retain table structure and image association information |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Parsing large party building PPT courses or multi-page PDF documents takes a long time. This duration covers the parsing needs of most documents, avoiding timeout interruptions |
chunkSettingMode | Manual configuration | Adjustments to chunking rules are required for transportation and sales-associated paragraphs. Manual configuration allows flexible adaptation to the special structure of documents |
Three Common Misconfigurations
- Split-related errors appear during parsing, with logs indicating chunking failure. The cause is that
customPdfParseis not enabled. PDF documents with embedded transportation and sales tables cannot correctly identify paragraph boundaries, triggering abnormal chunking logic. - Transportation and sales-associated fields are empty after document parsing, and compliance clause content cannot be extracted. The cause is that
customPdfParseis not enabled, and field information in structured tables is not correctly parsed. - Parsing interface calls time out. The cause is that the value of
PARSE_FILE_TIMEOUT_SECONDSis not adjusted. Parsing large party building courses takes longer than the default threshold, leading to task interruption.
How to Verify the Configuration Is Correct
- Upload a party building PDF document containing embedded transportation and sales tables. Confirm that the parsed text retains the complete row and column structure of the table.
- Review chunked text fragments. Confirm that party building themes and associated transportation and sales compliance clauses are not split into different chunks.
- Upload a single 500 MB party building PPT document. Confirm that the parsing task does not trigger a timeout error.
- Adjust
chunkSizeto 1100 characters. Verify that the length of chunked fragments matches the expected range.
