What the dataset for this use case looks like
The data sources for urban water utility party building learning Q&A mainly include documents exported from the internal party building management system, learning documents issued by superior party committees, branch three meetings and one lesson records, and annual party building work summaries. The update rhythm adjusts based on party building activity arrangements: monthly new monthly learning materials are added, and party course slides and party member assessment archives are updated quarterly. Document types include multi-page PDF manuals, table documents with multiple columns (such as party member learning attendance sheets, party fee collection lists), with fields covering party member ID, learning duration, assessment score, and units such as hours, yuan, and person-times. Some documents mix water utility business linkage content and party building requirements, have a clear structural hierarchy but have cross-page content connections.
What constraints these characteristics impose on the document parsing and chunking step
The long-text structure of party building documents requires that chunks are not split excessively within complete party course paragraphs, otherwise Q&A context will be broken. The presence of multi-column tables requires the parsing step to correctly merge cross-column content to avoid cell misalignment or data loss. Documents mixing business and party building content require accurate distinction of target fields to prevent non-party building content from being incorrectly included in the knowledge base. Bulk uploaded quarterly slide packages have large individual file sizes, which impose requirements on parsing timeout limits and upload caps. Some embedded images in documents mark details of water utility engineering and party building linkage, so parsing must correctly associate the images with corresponding text content.
How to set the configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the paragraph length of party building documents, retains complete context of party course speeches and learning reflections |
chunkSplitter | Split by title + paragraph | Matches the chapter hierarchy of party building documents, avoids splitting complete entries in branch meeting records |
customPdfParse | Enable multi-column text merging | Resolves common parsing misalignment issues for two-column party member attendance tables in water utility party building documents |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the full parsing time of annual party building summary PDFs with more than 200 pages per file |
UPLOAD_FILE_MAX_SIZE | 500 MB | Allows uploading bulk quarterly party course slides and assessment archive packages |
chunkSettingMode | Manual configuration | Flexibly adjusts chunking rules for documents mixing business and party building content |
Three common mistakes
- After uploading a multi-column party member attendance document, the parsing result shows cell content misaligned across columns. The cause is that the multi-column text merge configuration in
customPdfParseis not enabled, so the parsing engine cannot correctly identify the table column structure. - When uploading a single 150-page annual party building summary PDF, the parsing task returns a timeout error. The cause is that
PARSE_FILE_TIMEOUT_SECONDSis set below 200 seconds, which cannot complete full parsing of the long document. - Chunked Q&A results have disconnected context, such as splitting the front and back paragraphs of the same party course into independent segments. The cause is that
chunkSizeis set below 600 characters, which excessively splits complete text content.
How to verify the configurations are properly applied
- A test PDF containing a two-column party member attendance sheet may be uploaded, and the parsed table should be checked to confirm all cell content is within the correct columns with no cross-column misalignment.
- A single 200-page party building summary document may be uploaded, and it should be confirmed that the parsing task completes within 300 seconds with no timeout errors.
- The chunks in the knowledge base may be reviewed to confirm that complete party course paragraphs and section titles are retained with no forced splitting.
- A course slide compressed package larger than 500 MB may be uploaded, and it should be confirmed that the system prompts that the file exceeds the upload limit, matching the configured requirements.
