What this category of data looks like
Entities involved in this category are mostly emergency management bureaus, street and township emergency command centers, and similar organizations. Daily processed documents include duty records, early warning notices, consultation minutes, disaster situation rapid reports, emergency response plans, and material allocation slips, among others. Data sources include meteorological early warning systems, hydrological monitoring systems, emergency command platforms, grassroots disaster reporting systems, and video surveillance. The update frequency is daily. Document structures include standardized fields such as time, location, danger level, and response measures. Some documents include dedicated units, such as millimeters of rainfall, number of personnel, and tons of materials.
Constraints on document parsing and chunking
Real-time data updated at high frequency daily requires parsing and chunking to adapt to short-cycle batch input, to avoid timeouts that disrupt emergency response timelines. Multi-source, heterogeneous document formats — including concise early warning notices, long-form consultation minutes, and structured material allocation slips — require flexible chunking rules to match different structures. Standardized fields and units require chunking to retain key metadata, preventing splits from breaking the complete association between policy basis and disaster situation information. Emergency scenarios have high fault tolerance requirements; chunking must retain contextual connections to avoid gaps in policy basis caused by splitting.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the mixed structure of flood control documents that contain both policy provisions and real-time data, avoiding splitting that disrupts the complete semantics of policy basis |
chunkSplitter | Split by paragraph + heading | Adapts to the hierarchical structure of consultation minutes and early warning notices, retaining logical connections within documents |
PARSE_FILE_TIMEOUT_SECONDS | 120–180 seconds | Addresses parsing time for batch hydrological monitoring data and disaster situation rapid reports, matching the daily update task rhythm |
customPdfParse | Enabled | Adapts to PDF formats of flood control early warning notices and consultation minutes, retaining original layout and metadata |
chunkSettingMode | Manual configuration | Adjust chunking rules for different document types such as duty records and material allocation slips to meet flexible needs in emergency scenarios |
Three common mistakes
- Phenomenon: Some policy documents are not associated with model responses after upload. Cause:
chunkSettingModeis not configured correctly, the system does not trigger the document parsing process, or the chunking rules do not cover key fragments of policy provisions. - Phenomenon: Parsing timeout errors occur when uploading hydrological monitoring tables in batches. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout duration is insufficient to complete batch parsing of multiple tables. - Phenomenon: Fields are missing from parsed Excel-format material allocation slips. Cause: Chunking rules for table documents are not adapted, and the default chunking logic disrupts the row-column association of the table, leading to loss of key data due to splitting.
How to confirm configurations are set correctly
- Upload a standard flood control early warning PDF document, check if the parsed text retains the hierarchical relationship between headings and body text, to verify that the
customPdfParseconfiguration takes effect. - Upload a multi-page consultation minute document, check if the chunking results are split by paragraph with no cross-paragraph semantic breaks, to verify the
chunkSplitterconfiguration. - Upload a single-page hydrological monitoring report, wait for parsing to complete and check the task log, confirm that the parsing time does not exceed the set
PARSE_FILE_TIMEOUT_SECONDSthreshold. - Upload an Excel-format material allocation slip, check if the parsed fields are complete, to verify that the chunking rules adapt to the needs of structured tables.
