What the Data for This Category Looks Like
The data for declaration materials and file review for state-owned capital investment companies primarily comes from internal project proposal documents, state-owned assets supervision and administration record files, and investment decision files. Updates are concentrated around project declaration cycles, with routine updates for archiving. Documents include fixed-format approval forms, multi-page feasibility study reports, and compliance descriptions with structured tables. Core fields include project codes, investment amounts, and supervision document numbers. Units are mostly ten thousand yuan and years. The length of individual documents varies widely, ranging from a few pages of approval sheets to dozens of pages of feasibility study reports.
Constraints Imposed on Document Parsing and Chunking
These data characteristics impose multiple constraints on the document parsing and chunking process. First, the wide range of document lengths requires chunking to retain cross-page related content, avoiding splitting cross-page compliance descriptions and field information. Second, the presence of structured tables means general automatic chunking cannot preserve row and column correspondences, which easily leads to chaotic splitting of table content. Third, in batch parsing scenarios, it is necessary to distinguish currently uploaded documents from historically archived documents to avoid repeated parsing or confusion of declaration materials from different batches. Finally, concentrated declaration cycles require the parsing module to have sufficient response speed and fault tolerance to handle the volume of documents uploaded in batches.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | State-owned capital investment company declaration materials include cross-page compliance descriptions and associated fields. This length retains a single segment of core information while avoiding context fragmentation |
chunkSplitter | Mixed paragraph and fixed-length splitting | Balances the natural paragraph logic in declaration materials and the integrity of structured tables, preventing general chunking from destroying table row and column structures |
customPdfParse | Enabled | For declaration materials with fixed templates, custom parsing can accurately extract tables and fields, adapting to the format requirements of state-owned assets supervision documents |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Individual feasibility study reports may exceed general timeout limits. Extending the timeout ensures complete parsing of long documents |
chunkSettingMode | Manual mode | Adjusting chunking rules for different types of declaration documents (approval forms, feasibility study reports) is required. Automatic mode cannot adapt to structured content |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Declaration materials for state-owned capital investment companies may include a large number of attachments and diagrams. This upper limit covers conventional document sizes |
Three Common Misconfigurations
- Phenomenon: After uploading a multi-column structured Excel declaration table, question-and-answer accuracy is low, and chunking disrupts row and column correspondences. Cause: General automatic chunking is used, and the
chunkSplitterrule is not adjusted for multi-column tables, leading to incorrect splitting of table content. - Phenomenon: Historically archived documents are loaded and parsed together during batch parsing. Cause: An independent parsing context for currently uploaded documents is not configured, causing the
customPdfParsemodule to call historical caches and confusing declaration materials from different batches. - Phenomenon: Large-size PDF feasibility study reports fail to parse due to timeout. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout value cannot cover the parsing duration of long documents.
How to Confirm Proper Configuration
- Upload a single typical declaration document, view the parsed chunk list, and confirm that table content is not split into multiple independent chunks.
- Upload multiple different types of declaration materials, check the parsing task list, and confirm that only currently uploaded documents are included in the parsing scope.
- Test the question-and-answer function, enter a question containing table fields, and confirm that the returned content includes complete row and column association information.
- Upload a document larger than the default upload size, and confirm that the parsing task completes normally without timeout error prompts.
