What Data for This Category Looks Like
This category of data originates from national public resource trading platforms, local public resource trading platforms, engineering approval systems, and bidding supervision systems, with a daily update frequency. Commonly processed documents include bidding announcements, qualification pre-examination documents, project bidding documents, bid submissions, bid evaluation reports, successful bid candidate notices, and successful bid result announcements. Document structures include fixed fields such as section division, qualification requirements, bill of quantities, bid evaluation rules, and successful bid information. Units mostly involve standardized descriptions of project scale, construction period, and amount.
What Constraints These Characteristics Impose on Document Parsing and Chunking
Batch documents updated daily require parsing and chunking with stable processing capabilities to avoid timeout interruptions. Significant structural differences exist across multiple types of bidding documents, so the chapter division logic for different documents must be adapted to avoid splitting associated content such as qualification conditions and bill of quantities. Documents such as successful bid notices and bid evaluation reports involve sensitive information, so chunking must retain context association to ensure subsequent audit accuracy. The length of different documents varies widely, from hundreds-of-word announcements to tens-of-thousands-word project bidding documents, so chunking parameters must be flexibly adjusted to adapt to content density.
How to Configure Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Range/Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the content density of long documents such as project bidding documents and bid evaluation reports, and retains key context such as sections and qualifications |
chunkSplitter | Split by paragraph and title | Matches the chapter and section division structure of bidding documents, avoiding splitting associated content such as qualification conditions and bill of quantities |
customPdfParse | Enabled | Improves parsing accuracy for standard PDF format documents such as bidding announcements and successful bid notices |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of large tens-of-thousands-word project bidding documents, avoiding timeout interruptions during batch processing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Accommodates single large bid submission documents or aggregated bid evaluation report documents |
chunkSettingMode | Manual configuration | Flexibly adjust chunking parameters for different types of bidding documents, adapting to content with different structures such as bidding announcements and project bidding documents |
Three Common Misconfigurations
- Symptom: PDF parsing errors occur with no recent code changes. Cause: The
customPdfParseconfiguration is not enabled, or thePARSE_FILE_TIMEOUT_SECONDSsetting is too short, leading to timeout during parsing of large project bidding documents. - Symptom: After uploading multiple bidding documents, parsing results cannot distinguish their source files. Cause: File metadata binding configuration is not enabled, and chunking results do not carry identification fields such as original file name and document type.
- Symptom: Knowledge base search tests fail to return matching chunked content. Cause:
chunkSizeis set too large, causing key content to be split across different chunks, or core fields such as qualification conditions and successful bid information are omitted during chunking.
How to Verify Correct Configuration
- Upload a single bidding announcement of approximately 1000 characters, check the content integrity of the parsed chunks, and confirm that chunks do not split titles from their body content.
- Upload a single large project bidding document, wait for parsing to complete, confirm that no timeout error is triggered, and verify that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration matches the actual parsing duration. - Upload multiple different types of bidding documents, check whether each chunked result includes the original file name identifier, and confirm that multi-file parsing results can be clearly distinguished.
- Launch a knowledge base search test, enter core keywords such as qualification conditions and bill of quantities, confirm that the corresponding chunked content is returned, and adjust the
chunkSizeorchunkSplitterconfiguration to optimize matching accuracy.
