What the data for this use case looks like
Party building study data for state-owned industrial funds mainly comes from official party building documents issued by superior state-owned assets party committees, internal branch monthly study records, party lesson courseware, and party member study reflection archives. The update rhythm adjusts according to superior deployments. Official documents are updated quarterly in batches. Internal study records are generated in real time with branch activities. Document formats are mainly PDF and Word. Some courseware use PPT format. Structured documents include fields such as document number, issuing unit, study topic, and number of attendees. Number of attendees uses "person" as the unit. Document numbers use a format with a fixed prefix plus a serial number.
Constraints on document parsing and chunking
Official party building documents issued by superior state-owned assets party committees have fixed letterheads, headers and footers. Parsing must exclude redundant formatted content to avoid mixing irrelevant information into chunks. Internal branch study ledgers are mostly multi-row and multi-column Excel tables with structured fields including attendees and study reflections. Direct character-based chunking breaks table logic. Extract structured content first before splitting. Party lesson courseware’s chapter pages are bound to main body content. Chunking must follow chapter hierarchy logic. Forced page-by-page splitting will break content connections. Internal documents generated in real time have inconsistent formats. Multiple parsing rules must be adapted to reduce parsing failure rates. State-owned industrial fund party building documents must strictly retain document hierarchy and source identifiers to ensure chunks can be traced back to original documents.
Configuration Settings
These configurations are formulated for FastGPT v4.17.0
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the chapter and paragraph length of party building documents, avoids over-splitting that breaks context, and controls single-chunk vector dimensions |
chunkSplitter | Split by paragraph + title | Matches the hierarchical structure of party building documents, preserves chapter logic, and avoids content fragmentation caused by cross-title splitting |
customPdfParse | Enable header and footer filtering rules | Filters fixed letterheads, headers and footers from superior documents, reduces redundant content included in chunking scope |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Meets upload requirements for large party building study manuals and multi-page courseware, supports batch document processing scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing time of large PDF documents, prevents parsing task failure due to timeout |
chunkSettingMode | Manual configuration mode | Customizes chunking rules for the special formats of party building documents, adapts to non-general document structures |
Three Common Misconfigurations
- Phenomenon: An error "the argument ‘windows-1252’ is invalid encoding" occurs when uploading PPT documents. Cause: Custom encoding adaptation rules are not configured. Some old encoding formats embedded in party building document PPTs cannot be recognized by the default parsing engine.
- Phenomenon: Parsing results for uploaded Excel study ledgers are empty or fields are disordered. Cause: Structured table parsing mode is not enabled. Direct character-based chunking breaks the table’s row and column structure, leading to incorrect field extraction.
- Phenomenon: Chunk results contain large amounts of header and footer content, and cannot be associated with the correct study topic. Cause: The
customPdfParseheader and footer filtering configuration is not enabled, so redundant document format content is included in the chunking scope.
How to Confirm Configurations Are Correct
- Upload an official party building PDF document issued by a superior. Check if the parsing result has removed the letterhead, headers and footers, and confirm that the
customPdfParseconfiguration is active. - Upload an Excel branch study ledger. Check if the parsing result retains structured fields such as number of attendees and study topic, and confirm that chunking does not break table logic.
- Adjust the
chunkSizeparameter, then upload a long text party building material. Check if the chunk length matches the preset range, and confirm that thechunkSizeconfiguration is active. - Upload a single party building courseware larger than 500 MB. Check that no timeout occurs during upload and parsing, and confirm that the
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSconfigurations are reasonable.
