What This Category of Data Looks Like
Data in the policy and regulatory basis domain for refinery and chemical production primarily comes from official normative documents released by the National Energy Administration, the State-owned Assets Supervision and Administration Commission of the State Council, and petroleum and petrochemical industry associations. It also includes internal enterprise regulations covering safety production, environmental emissions, and production scheduling. Update frequency aligns with official policy release cycles, with no fixed schedule. Internal enterprise regulations are updated quarterly or semi-annually. Document structures include fields such as document number, issuing unit, release date, clause number, and applicable scenario. Units follow industry standards including mg/m³, MPa, and hours. The length of a single clause typically falls between 300 and 800 characters.
Constraints for Citation Sources and Traceability
Official document numbers and issuing units are core identifiers of policy legitimacy. Traceability processes must accurately match and return this metadata. Returning only text fragments prevents verification of the validity of cited basis content. Data updates have no fixed cycle. Latest documents must be synchronized regularly to ensure cited content remains up to date. Documents include clear clause numbers. Citations must target specific clauses. Returning only paragraph text does not meet compliance traceability requirements. Industry standard units for fields must be matched during retrieval. This avoids retrieving invalid content due to unit mismatches.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 1200–1800 characters | Single clauses in refinery policies are mostly 300-800 characters. This range covers 2 to 3 complete clauses, avoiding truncation of critical basis content |
| Reranking | Enabled | Policy text contains a large number of similar statements. Reranking filters irrelevant candidate segments and improves citation accuracy |
| Similarity Threshold | 0.75–0.85 | Policy text has high rigor. A threshold that is too low will introduce irrelevant clauses, while a threshold that is too high will miss valid basis content |
responseData | Include document number, release date | This parameter can be configured to return core metadata of policies, meeting traceability requirements |
detail | Enable full segment | Policy citations must retain clause context to avoid taking content out of context |
| Single Search Limit | Top 6 results | Policy basis for a single scenario usually does not exceed 5 entries. The top 6 results cover most business needs |
Three Common Configuration Mistakes
- Enabling reranking results in empty citations. The cause is that the similarity threshold is set too high, and reranking filters all retrieved candidate segments.
- Returned citation fragments do not include official document numbers. The cause is that the
responseDataparameter is not configured to return metadata fields, and only text content is returned. - Citation fragments are accidentally truncated. The cause is that the
quoteMaxTokenvalue exceeds the context length supported by the model, triggering system-level truncation.
How to Verify Successful Configuration
- Launch a policy Q&A test, and check whether returned results include metadata such as document number and release date.
- Adjust the similarity threshold, and observe changes in the number of retrieved fragments to confirm the threshold configuration takes effect.
- After enabling reranking, compare citation fragments before and after enabling to confirm the reranking function operates normally.
- Check system logs to confirm that the
quoteMaxTokenparameter does not trigger truncation errors, and that returned fragment lengths meet expectations.
