What this category of data looks like
Typical stakeholders include development and reform departments, industry authorities such as housing and urban-rural development, transportation, water resources, public resource trading centers, and bidding agencies. Daily generated documents include bidding announcements, qualification pre-examination documents, bidding documents, tender documents, bid evaluation reports, successful bid candidate notices, and successful bid result announcements. Data sources are the national public resource trading platform, local trading platforms, project approval systems, and bidding and tendering supervision systems. Data is updated daily. Documents contain dedicated fields such as qualifications, performance, bill of quantities, construction period, and more. Structural differences vary significantly across document types.
What constraints do these characteristics impose on the document parsing and chunking process
The data characteristics of this category impose multiple constraints on the document parsing and chunking process. First, daily high-frequency updates require the parsing process to have stable batch processing capabilities, to avoid parsing delays that affect the timeliness of service inquiries and responses. Second, there are diverse document types with large structural differences. Short announcements and long bidding documents have different chunking requirements, requiring support for different splitting logic. Third, dedicated fields such as bid sections, bill of quantities, and qualification requirements must retain full contextual relevance. Critical information must not be broken due to chunking, otherwise the accuracy of subsequent service inquiries and responses will be affected. Fourth, parsing errors may directly be linked to project advancement risks, so the accuracy of parsing and chunking must be ensured.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale for This Setting |
|---|---|---|
chunkSize | 800–1200 characters | Ensures paragraph integrity for long documents such as bidding documents and bid evaluation reports, and avoids splitting key business fields such as bid sections and bills of quantities |
chunkSplitter | Split by title + paragraph | Matches the hierarchical title structure of documents such as bidding announcements and successful bid notices, and retains contextual relevance of information |
customPdfParse | Enabled | Filters non-body content such as signatures, headers, and footers in bidding PDFs, improving parsing accuracy of core text |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Meets the full parsing time requirements for long bidding documents and batch tender documents, avoiding parsing process interruptions due to timeouts |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Accommodates upload requirements for large bidding documents and batch tender documents, adapting to daily data processing scale |
chunkSettingMode | Manual configuration | Adjusts chunking parameters for different document types, meeting personalized needs for specific scenarios |
Three Common Mistakes
- Symptom: When deploying FastGPT v4.17.0 via local Docker, calling PDF parsing results in a connection failure error, or the parsing status remains unchanged for a long time after uploading a document. Cause: Local service port mapping for
customPdfParsewas not configured correctly, so the FastGPT container cannot connect to the local parsing service. - Symptom: After uploading a bidding document, the parsing result shows missing bid section information or empty bill of quantities fields. Cause:
chunkSizewas set too small, splitting complete bid section clauses and list items into multiple unrelated chunks. - Symptom: When uploading batch tender documents, some documents fail parsing due to timeout. Cause:
PARSE_FILE_TIMEOUT_SECONDSwas set lower than the actual parsing time, causing long document parsing to interrupt.
How to Confirm the Configuration is Correct
- Upload a single typical bidding document, such as a bidding announcement or large bidding document, and check the parsed chunked content to confirm that key fields such as bid sections and bills of quantities are not split and broken.
- Check the parsing logs to confirm there are no error messages such as connection timeouts or unsupported file formats, and verify that the
PARSE_FILE_TIMEOUT_SECONDSsetting matches the actual parsing time. - Upload a PDF document with signatures, headers, and footers, and verify that
customPdfParsefilters out redundant non-body content and retains core business text. - Adjust the
chunkSizeparameter, compare parsing results under different settings, and confirm that chunking integrity meets the requirements of the current scenario.
