Policy and Regulatory Basis Q&A for Hazardous Chemical Storage and Transportation: Multi-turn Dialogue and Prompting

What this type of data looks like

This data draws primarily from official normative documents, national standards, and industry standards released by the Ministry of Emergency Management, the Ministry of Transport, and the Ministry of Ecology and Environment. Updates trigger when new policies are released, with no fixed cycle. Individual documents span several thousand to tens of thousands of characters. Each document follows a fixed structure, including fields such as document number, issuing authority, effective date, applicable scenarios, storage and transportation operation requirements, and penalty clauses for violations. Fields include specific numerical units: storage volume uses cubic meters, transportation distance uses kilometers, and flash point uses degrees Celsius.

Constraints on multi-turn dialogue and prompting

Individual policy documents have long length, and contain large volumes of specific numerical values and technical terms. Multi-turn dialogue must retain full context to follow up on user questions about clause details and document number associations. Policy fields include clear effective dates and applicable scenarios. Prompting must guide the model to annotate the issuing authority and effective time of the corresponding clause when responding, to avoid confusion between new and old policies. Policy requirements vary significantly across different storage and transportation scenarios. Multi-turn dialogue must clearly define the current scenario under discussion, to avoid applying clauses across scenarios. Some policy clauses have hierarchical relationships. Multi-turn dialogue must support users to trace clause sources layer by layer, to ensure response accuracy.

Configuration Settings

Reference only; verify against the target FastGPT release and deployment documentation.

| Question optimization switch | Enabled | User questions may include vague descriptions of storage and transportation scenarios. Optimization enables accurate matching of corresponding policy clauses |

| chatId configuration | Use unique identifiers within a session | Prevents confusion between conversation contexts of different users, and ensures continuity of multi-turn dialogue |

| variables configuration | Preset "storage and transportation scenario" and "policy document number" variables | Hazardous chemical storage and transportation policies are categorized by scenario and document number. This helps the model accurately locate relevant clauses |

| Single retrieval count | Top 3–5 entries | A large number of policy documents exist. Filtering the most relevant clauses avoids context overload |

| messages configuration | Retain the most recent 10 rounds of conversation content | User questions about policy clauses mostly focus on the most recent discussion range. Excessively long historical content interferes with model judgment |

Three Common Configuration Errors

• A 422 status code occurs when calling the dialogue interface. This happens if the messages or variables parameters are not passed correctly, or if the parameter format does not meet requirements. For example, passing the array-type messages as a string.
• Conversation records are shared between different users. This happens if an independent chatId is not assigned to each session. Using a shared chatId causes context confusion.
• Valid content cannot be extracted after uploading hazardous chemical policy documents. This happens if the uploaded file format is not within the supported range of plain text, PDF, or Word, or if the document contains large amounts of non-policy redundant content.

How to Verify Correct Configuration

• Initiate a question that includes a specific storage and transportation scenario. Confirm that the model’s response references the document number and effective date of the corresponding policy.
• Initiate a follow-up question. Confirm that the model follows up on the content of the previous round of discussion, with no context breakage.
• Check that the session’s chatId is unique. Confirm that conversation records from different sessions do not interfere with each other.
• Upload a hazardous chemical policy document. Confirm that the system correctly extracts fields and clause content from the document.
