What the data for this category looks like
Data for gas intelligent due diligence reports comes from ledgers of gas operation enterprises, pipeline network inspection archives, gas source purchase agreements, terminal gas consumption statistical reports, and safety filing documents from local regulatory authorities. This data follows a set update schedule: monthly operational data updates each month, quarterly inspection archives are archived each quarter, and annual cooperation agreements and filing documents update periodically. Document structure includes four modules: enterprise qualification, pipeline network parameters, gas consumption statistics, and safety inspection. Fields include pipeline nominal diameter (unit mm), average daily gas consumption (unit 10,000 cubic meters), pipeline network pressure value (unit MPa), inspection point coordinates, and others. A complete single report typically has a text length in the tens of thousands of characters range.
What constraints do these characteristics impose on model access and configuration
Multi-field professional units, long text structure, and periodic updates create multiple constraints for model access and configuration. Multi-fields with professional units require standardized mapping rules for configuration fields. This avoids unit ambiguity during vector recall. A single report with tens of thousands of characters requires adjusting context window and chunking parameters. This prevents core compliance and operational data from being truncated. Periodically updated data sources require configuring incremental synchronization trigger logic. This matches the update rhythm of monthly operational data and quarterly inspection archives. Longitude and latitude point fields need vector modeling. This requires specifying embedding model parameters adapted to spatial features.
How to set the configuration
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the tens of thousands of characters length of a single gas due diligence report, preventing core compliance and operational data from being truncated |
chunkSize | 1500–2000 characters | Covers complete professional modules such as pipeline network parameters and gas consumption statistics in gas due diligence reports, avoiding splitting key fields |
embeddingModel | text-embedding-3-large | Provides stable vector representation for structured numerical values, professional units, and longitude and latitude points, adapting to the professional characteristics of gas data |
RECALL_TOP_N | Top 8–10 entries | Covers three core data modules: qualification, operation, and safety, avoiding missing key detailed dimensions in recall results |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Adapts to the compressed package size of a complete single gas due diligence report, reserving reasonable buffer space |
SYNC_INCREMENTAL_INTERVAL | 720 hours | Matches the update rhythm of monthly operational data, ensuring the timeliness of recalled data |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require analysis on a case-by-case basis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: In platform version 4.9.12, invoking the knowledge base produces output that includes the phrase "citation mark: [1]". Cause: The citation mark output switch for knowledge base recall results is not turned off, or the automatic filtering rule for citation marks is not configured.
- Phenomenon: After uploading a gas due diligence report, some longitude and latitude fields are empty or parsed incorrectly. Cause: Field parsing rules for longitude and latitude formats are not configured, or the chunk length is set too small, causing longitude and latitude coordinates to be split and truncated.
- Phenomenon: Data synchronization tasks time out, returning status code 504. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. The default timeout duration is insufficient to handle parsing of long text reports with tens of thousands of characters.
How to verify successful configuration
- Upload a complete single gas due diligence report, check whether the parsed field list includes preset professional fields, and confirm that field units match the original data.
- Initiate a test invocation, input queries related to gas due diligence, check whether valid information is missing from the output content, and adjust corresponding configuration parameters until requirements are met.
- View the data synchronization logs, confirm that incremental synchronization tasks trigger according to the preset cycle, and that the latest operational data has completed recall and update.
- Conduct test invocations, check the output content to confirm there are no unexpected extra marks, and adjust citation mark-related configuration items until requirements are met.
