What the data for this category looks like
Data for refined petroleum product sales policy and regulatory basis Q&A comes from official sources. These include management measures, compliance guidelines and tax notices published by the National Energy Administration, provincial commerce departments and the Ministry of Finance. It also covers national standards and compliance manuals for the petroleum and petrochemical industry. National-level policies update every six months to one year. Local supporting policies update more frequently. Some regions adjust policies quarterly. Each document includes standard fields: document number, issuing authority, effective date, clause number, scope of application and specific compliance requirements. Compliance requirements cover retail prices and storage capacity standards. Most units use industry standard formats such as yuan per liter and cubic meters.
How these characteristics create constraints for citation traceability
Multi-department, multi-level source requirements mean traceability must clearly mark issuing authorities and authority levels. This avoids confusion over effectiveness differences between policies at different tiers. Differences in update frequencies require the knowledge base to align synchronization for national and local documents. This prevents citing expired policies. The clause-based structure of documents requires traceability to target specific clauses. This ensures full traceability for compliance audits. Document numbers and clause numbers serve as unique traceability identifiers. These must be bound during configuration to avoid forged citations.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Single clauses of refined petroleum product policies are mostly 50-300 words. Total citation tokens must cover complete clauses and metadata to avoid truncating critical compliance content |
responseData | Return only file metadata + original clause text | Refined petroleum product sales compliance traceability requires clear document numbers, issuing authorities and specific clauses. Returning only summaries fails to meet audit requirements |
detail | Enable full traceability | Precise matching of clause-level content is required. Returning only file-level citations fails to meet compliance review needs for refined petroleum product sales |
| Knowledge base synchronization cycle | Synchronize every 7 days | National policy update cycle is six months. Local policies update more frequently. Regular synchronization ensures timeliness of traceable documents |
| Single recall limit | Top 6 results | Valid relevant documents for refined petroleum product policy questions usually do not exceed 5. Too many recalls exceed the context window |
Three common configuration errors
- Issue: The citation variable dropdown is empty when applying variables at the knowledge base search node. Cause: The knowledge base ID list variable was not configured in system variables in advance, or the variable format does not match the array format required by FastGPT.
- Issue: Logs cannot distinguish citations from different sources. Cause: The
responseDataconfiguration was not set to return unique document identifier fields. Logs only display content and fail to distinguish sources of different policy documents. - Issue: The large language model outputs forged citation IDs or retains original citation markers. Cause: The full traceability mode of the
detailconfiguration was not enabled, or knowledge base documents do not have unique clause-level identifiers. The model cannot match real citation IDs, and marker characters in input and output were not cleaned.
How to verify a complete configuration
- Submit a test that includes a specific refined petroleum product policy question, such as "2024 domestic refined petroleum product retail price management requirements". Check if the output includes document numbers, issuing authorities and specific clause content.
- View the FastGPT v4.17.0 knowledge base synchronization log. Confirm that policy documents from the last 7 days have completed synchronization, with no failed or skipped records.
- Check the workflow configuration. Confirm that the knowledge base search node is bound to the correct system variable, and the dropdown can normally select the corresponding variable parameter.
- View the call log. Confirm that each citation has a unique traceability identifier, with no forged or missing citation markers.
