What the data for this category looks like
Document sources for civil aviation airport party building learning Q&A include official red-headed documents issued by the airport party affairs department, theme party day learning courseware, party member required knowledge manual, and superior party building work deployment notices. Update rhythm: superior party building deployments adjust dynamically per industry and central requirements. Internal learning materials are updated once per month. Annual party building summaries are supplemented quarterly. Documents include fixed official document fields: document number, issuing unit, issuing date. They also contain chapter-style learning content and Q&A-style knowledge points. Units are typically articles, sections, or instances.
What constraints these characteristics impose on the "document parsing and chunking" link
- Retain metadata such as document number and issuing unit during parsing, per the fixed official format of civil aviation party building documents, to avoid losing key identifiers.
- Do not break chapter logic when chunking content. Split content to match the document’s title hierarchy, to prevent complete learning units from being split across titles. This matches the structure of chapter-style courseware and Q&A-style knowledge points.
- Use parsing tools that support batch processing, with quickly configurable uniform chunking parameters, to handle monthly updated batch learning materials.
- Use chunking parameters that support flexible adjustment, to accommodate wide variations in document volume. Volume ranges from a few pages of required knowledge manuals to dozens of pages of annual party building summaries.
- Retain semantic integrity when chunking, to avoid splitting complete single knowledge point content. Most party building knowledge points are short Q&A pairs.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Matches the semantic length of a single Q&A pair or single chapter in civil aviation party building documents, avoiding splitting complete knowledge points |
chunkSplitter | Split by headings | Adapts to the document’s chapter structure, retaining the title hierarchy logic of theme party day courseware and red-headed documents |
customPdfParse | Enable Marker parsing | Adapts to complex formats such as headers, footers, and document number bars of civil aviation red-headed documents, resolving abnormal issues with some built-in parsers |
UPLOAD_FILE_MAX_SIZE | 500 MB | Covers the upload needs of large-volume documents such as annual party building summaries, preventing parsing tasks from failing due to volume limits |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing time of large-volume documents, preventing tasks from being interrupted by timeout mid-execution |
chunkSettingMode | Manual configuration | Flexibly adjust chunking parameters for different types of documents such as required knowledge manuals, courseware, and red-headed documents |
Three common mistakes
- Phenomenon: When using the built-in PDF parser of FastGPT v4.17.0, metadata such as document number and issuing unit are lost for some civil aviation party building red-headed documents. Cause: The built-in parsing engine does not adapt to the fixed official document format, and fails to extract key identifiers from headers and footers.
- Phenomenon: When uploading annual party building summary documents with volume exceeding the preset limit, parsing tasks fail directly and return status code 413. Cause: The
UPLOAD_FILE_MAX_SIZEparameter is not adjusted, exceeding the default upload volume threshold. - Phenomenon: Results returned by the Q&A tool split the complete Q&A content of a single set of party member required knowledge points. Cause: The
chunkSizeparameter is set too small, not matching the semantic length of the knowledge points.
How to confirm the configuration is correct
- Upload a standard civil aviation party building red-headed document. Check if the parsed metadata includes document number, issuing unit, and issuing date, to confirm that the
customPdfParseconfiguration takes effect. - Upload test documents of different volumes. Check if parsing tasks complete within the preset time, to confirm that the value of
PARSE_FILE_TIMEOUT_SECONDSis reasonable. - Randomly extract chunked content. Check if the complete semantics of a single party building Q&A pair are retained, to confirm that the
chunkSizeandchunkSplitterconfigurations match the document structure. - Batch upload monthly party building learning materials. Check if parsing tasks can be completed in batch, to confirm that the overall configuration adapts to batch processing needs.
