What This Category of Data Entails
Policy and regulatory basis data for the metal material processing sector is primarily sourced from industry normative documents, national standards, and industry standards issued by the National Development and Reform Commission, Ministry of Industry and Information Technology, and provincial and municipal industry and information technology departments. Data updates align with the release of official policies, with no fixed cycle. Most documents follow official document formats, including fields such as document number, issuing authority, effective date, scope of application, and specific clauses. Clause content is divided by chapter. Some documents include quantitative indicators and unit requirements, covering sub-scenarios such as capacity replacement, environmental emissions, product quality inspection, and similar areas.
Constraints Imposed on Multi-turn Dialogue and Prompt Engineering
The fixed structure of policy documents requires multi-turn dialogue to track metadata such as document numbers and effective dates mentioned by users. This prevents loss of key supporting information during follow-up questions. The lack of a fixed update cycle requires prompt engineering to explicitly require reference to the currently latest effective policy version. This avoids returning revoked documents. The chapter-based division of clauses requires multi-turn dialogue to link the user’s current question to the specific clause range mentioned previously. This ensures responses are targeted. The differences in policy scope of application fields require prompt engineering to explicitly limit sub-scenarios within the metal material processing sector. This narrows the retrieval scope and prevents incorrect recall of cross-domain policies.
Configuration Setup
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
| Conversation ID Binding | Bind project code + conversation sequence | Ensure multi-turn dialogue context is tied to a specific metal material processing policy consultation project, preventing cross-project confusion |
| Context Retention Turns | Last 4 turns | Metal material processing policy Q&A often involves clause tracing. 4 turns cover conventional follow-up question logic, avoiding context overflow |
| Custom Variables | Inject current effective policy version number | Ensure responses reference the latest released and valid policy versions, meeting compliance requirements in the sector |
| Single Retrieval Limit | Top 5 entries | Policy documents often have associated entries. 5 entries cover different levels of policies on the same topic, avoiding interference from redundant information |
| Document Chunking Threshold | 1000–1500 characters | Match the length of single clauses in metal material processing policy documents, ensuring complete clause logic is retained after chunking |
Three Common Misconfigurations
- Issue: A 503 error is returned when uploading metal material processing policy documents to the dialogue page, but background logs show the file upload was successful. Cause: The document chunking threshold is not set to match the length of metal material processing policy documents, leading to service exceptions triggered by large file parsing timeouts.
- Issue: Subsequent responses in multi-turn dialogue do not link to previously mentioned policy document numbers. Cause: The conversation ID binding rule is not configured correctly, leading to failure to properly associate context. Each round of dialogue retrieves information independently, resulting in data loss.
- Issue: Responses reference revoked policy documents. Cause: The current effective metal material processing policy version filtering condition is not injected into custom variables, leading to recall of expired policy documents.
How to Verify Proper Configuration
- Upload an official policy document from the metal material processing sector. Check if the parsed chunked content includes core fields such as document number and effective date.
- Launch two linked policy Q&A sessions. For example, first query the clauses of a specific document number, then follow up to ask about the applicable scenarios of that clause. Check if subsequent responses retain the document number mentioned in the first session.
- Test uploading a policy file clearly marked as revoked. Confirm the system does not recall this type of document, verifying that the version filtering configuration is active.
- View the binding information in dialogue records. Confirm that cross-project confusion of dialogue contexts does not occur across different projects.
