What the data for this category looks like
The data for chemical raw material intelligent due diligence reports mainly comes from the public database of China Chemical Information Center, hazardous chemical filing information from local emergency management departments, customs clearance data from the General Administration of Customs, and reports from third-party testing institutions. The data update rhythm is layered: basic production filing information is updated quarterly, product price and supply and demand data is updated monthly, and single-batch compliance test reports are released with production batches. The structure of a single report document includes a basic information table, production process parameter table, compliance test data table, and upstream and downstream transaction record attachments. Fields include CAS registry number, production license number, density (unit: g/cm³ at 20℃), flash point (unit: ℃), packaging specification (unit: kg/barrel), etc.
What constraints these characteristics impose on the "model access and configuration" link
The layered update rhythm of chemical raw material data requires that incremental synchronization rules with periodic intervals be configured during the model access phase, to adapt to the update frequencies of different data and avoid repeated pulling or delayed updates. The existence of the unique identifier CAS number requires that precise matching rules be configured for model retrieval, to prevent interfering data from non-target categories from being mixed in. The document structure with multiple coexisting formats requires that the parsing link support multiple file formats such as PDF and Excel, and that sufficient parsing timeout parameters be configured. The diversity of field units requires that the model support unit normalization processing, unify the expression formats of data from different sources, and improve the model's recognition accuracy for parameters.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
similarity threshold | 0.85–0.92 | Based on the precise matching requirement for CAS numbers, a higher threshold filters search results for non-target chemical raw materials |
incremental synchronization interval | Once per month (supply and demand data), Once per quarter (filing data) | Matches the layered update rhythm of chemical raw material data, reduces server resource usage |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the file size of single compliance test report PDFs, avoids interruptions due to parsing timeouts |
maxContext | 8000–12000 characters | Carries multiple sets of parameter information in chemical raw material due diligence reports, ensures the model can access complete context |
unit normalization switch | Enabled | Unifies unit expressions for data from different sources, improves the model's recognition accuracy for fields such as density and flash point |
The parameter values provided on this page are all conventional recommendations, used as a starting point for configuration. The actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing the configuration.
Three common mistakes
- Symptom: The model call returns error code
1742438308259968with the prompt "Model does not exist or cannot be accessed". Cause: Thedeep search-r1:7bmodel has not been configured in the FastGPT model channel list, or the access permission for the corresponding channel has not been enabled. - Symptom: The model test returns empty results or missing fields. Cause: The
unit normalization switchhas not been enabled, so the unit expressions of data from different sources cannot be unified by the model, and valid parameters cannot be matched. - Symptom: A timeout error occurs when parsing chemical raw material test reports. Cause:
PARSE_FILE_TIMEOUT_SECONDShas not been adjusted to above 600 seconds, and parsing of single large-volume PDF reports is triggered before completion.
How to confirm the configuration is complete
- Enter the model test interface, enter a query statement containing the target CAS number, and verify that the returned results include the preset fields of the corresponding chemical raw material.
- Check the data source synchronization log, confirm that the monthly and quarterly incremental synchronization tasks have been executed successfully with no failed records.
- Upload a single chemical raw material compliance test report PDF, verify that the parsed fields include preset parameters such as density and flash point.
- Check the system error log, confirm that there are no error records such as "model does not exist" or "parsing timeout".
