What this category of data looks like
Primary sources for shipbuilding sector policy and regulatory basis data include official public documents from the Ministry of Industry and Information Technology, the Ministry of Transport, and the National Maritime Administration, plus industry standards released by the China Shipbuilding Industry Association. New policy releases trigger data updates, with no fixed cycle. Single documents typically include fields such as policy document number, issuing authority, effective date, applicable ship type scope, and core clause content. Some technical policies add quantitative indicators like gross tonnage, deadweight tonnage, and construction period. Document structures have clear hierarchical levels, with chapters and sections labeling individual clauses.
What constraints these characteristics impose on the citation sources and traceability workflow
Multi-department official sources require the traceability process to verify the compliance of the publishing entity for cited content. Only excerpts from official public documents are permitted. The lack of a fixed update cycle requires configuration of a scheduled synchronization mechanism, ensuring policies stored in the knowledge base remain the latest effective versions. Documents with document number and effective date fields require traceability results to display the corresponding policy number and effective time, to avoid citing expired clauses. Exclusive fields such as applicable ship type and quantitative indicators require binding filtering conditions like ship type and gross tonnage during recall, to avoid retrieving mismatched policy content.
Configuration guidelines
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Matches the average length of core clauses in single shipbuilding policy documents, to avoid truncating key compliance requirements |
| Maximum number of citations | Top 3–5 entries | Shipbuilding policy documents have dense content; excessive citations lead to redundant responses |
detail | Enable full traceability information | Requires displaying policy document number, issuing authority and effective date, matching the inherent fields of the document |
responseData | Return only official source excerpts | Filters non-official policy interpretation content to ensure citation compliance |
| Single recall limit | Top 10 entries | Covers multiple associated policies in the same production scenario, to avoid missing compliance basis |
| Traceability response timeout | 60 seconds | Ensures stability of official document retrieval, avoiding process interruptions due to excessive waiting time |
Three common configuration errors
- Phenomenon: Responses do not prioritize citing the top-ranked policy document in the knowledge base. Cause: No reordering rule configured to sort by effective date in descending order. Only initial recall similarity sorting is used, causing older policies to be selected first.
- Phenomenon: The number of policy documents cited in responses exceeds expectations. Cause: No reasonable maximum number of citations is set, or the recall limit is configured too high, leading to redundant content being included in responses.
- Phenomenon: Traceability results do not display policy document number and effective date. Cause: The
detailconfiguration item is not enabled, or no document field extraction rule is bound, making it impossible to match the exclusive traceability fields of policy data.
How to verify correct configuration
- Upload a latest shipbuilding policy document, initiate relevant queries, and check if the traceability information displayed in responses includes the policy document number and effective date.
- Adjust the maximum number of citations configuration, initiate multiple similar queries, and verify that the number of cited documents in responses matches the expected value.
- Simulate recall scenarios for old and new policies, and check if responses prioritize policies with more recent effective dates.
- Check system logs to confirm that each traceability request successfully obtains the metadata of the corresponding policy document, with no missing fields.
