What Data for This Category Looks Like
Data for this category of declaration materials and case records comes primarily from internal enterprise trade systems, customs clearance portals, and third-party inspection agency reports. Data is generated and updated with each trade batch. A single case record includes fixed fields such as trade category, declared quantity, unit price, customs clearance number, and inspection conclusion. Units are mostly tons, barrels, yuan per unit weight or volume. Documents mostly combine structured tables and scanned files. The length of a single case record ranges from hundreds to thousands of characters.
Constraints Imposed by These Characteristics on Multi-turn Dialogue and Prompts
Fixed fields and specific unit requirements mean prompts must clearly specify standard units for extracted fields, to avoid recognition errors between tons and barrels, or yuan and US dollars. The mixed format of scanned files and structured documents requires multi-turn dialogue workflows to support first identifying key information in images, then combining structured data to complete verification. Large differences in the length of single case records require dynamic adjustment of context truncation ranges, to prevent key information loss from exceeding dialogue window limits. Associated queries for multiple trade batches require variables and messages parameters to retain context variables such as declaration entities and customs clearance numbers from historical sessions, to ensure accurate cross-turn information association.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Question Optimization | Enabled | Keywords in bulk commodity declaration materials are scattered; optimization improves recall accuracy of key information |
| Maximum Context | 8000–12000 characters | Adapts to the length difference of single case records, which ranges from hundreds to thousands of characters |
| Single Search Limit | Top 5 entries | Avoids excessive redundant case information interfering with review judgments |
variables | Bind customs clearance numbers and trade categories from historical sessions | Supports context association for multi-turn dialogue, ensuring accurate cross-turn parameters |
messages | Retain the most recent 8 turns of dialogue content | Covers historical questions and parameter transfers in multi-turn review workflows |
| Image Display Toggle | Enabled | Adapts to scanned files and inspection report images included in declaration materials, meeting visual review requirements |
Three Common Configuration Mistakes
- Phenomenon: Incorrect units are extracted for trade category and quantity fields, such as identifying barrels of crude oil as tons. Cause: Prompts fail to clearly specify standard units for corresponding categories, and do not define field extraction rules.
- Phenomenon: Inspection report images uploaded to the knowledge base cannot be displayed in dialogue results, only text descriptions are returned. Cause: The image display configuration is not enabled, and prompts do not explicitly require recognition and display of image content.
- Phenomenon: Historical customs clearance numbers are lost during cross-turn queries, making it impossible to associate corresponding case records. Cause: The
variablesparameter is not configured correctly, and key context variables from historical sessions are not retained.
How to Verify Proper Configuration
Reference only; verify against the target FastGPT release and deployment documentation.
- Initiate a query requesting trade category and quantity, check whether returned results accurately extract corresponding fields and standard units, and adjust prompts until requirements are met.
- Upload a document containing inspection report images, initiate a query, check whether dialogue results display image content, and confirm the image display toggle is enabled.
- Initiate two or more associated queries, such as first querying a case record by customs clearance number, then querying the quantity of that case record, check whether the historical customs clearance number is correctly associated, and confirm the
variablesandmessagesparameters are configured correctly. - Test context retention for multi-turn dialogue, initiate multiple rounds of queries, check whether historical parameters are correctly called, and adjust values for related configuration items.
