What this category of data looks like
Urban gas policy and regulatory basis data is primarily sourced from official public documents released by the Ministry of Housing and Urban-Rural Development, housing and urban-rural development commissions of various provinces and cities, and gas industry associations. This data includes national mandatory standards, local management rules, and enterprise operation specifications. National-level documents are revised every 1 to 2 years. Local rules are updated alongside adjustments to local policies. Document structure includes fields such as issuing authority, effective date, applicable region, and core clauses. National mandatory standards have uniform identification numbers. Most local documents define their applicable scope based on prefecture-level or county-level cities.
Constraints imposed on multi-turn dialogue and prompt engineering
Policy data is distributed across national, local, and enterprise levels. Multi-turn dialogue requires connecting compliance requirements across different levels from multiple documents. Prompt engineering must clearly guide retrieval of documents from the correct level. The localized applicable region field requires the dialogue to first confirm the user’s administrative region before accurately retrieving matching local rules. Individual policy documents are lengthy. Multi-turn context must limit the range of retrieved valid clauses to prevent redundant information from disrupting dialogue logic. Policy update cycles vary. Prompt engineering must include priority judgment rules for the latest documents to ensure returned content aligns with currently valid versions.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
chatId | Bind to user conversation thread | Used to associate multi-turn dialogue context, ensuring consistent logic for continuous policy Q&A and aligning with user habits of gradually confirming compliance details |
messages | Limit single-turn content to no more than 1200 characters | Individual urban gas policy clauses are lengthy. Limiting single-turn message length prevents context overflow and adapts to dialogue interface display logic |
variables | Inject "local administrative region" and "consultation scenario" | Used to accurately match local rules of corresponding provinces and cities and user consultation scenarios, such as resident installation applications and gas safety inspections |
| Maximum context | Retain the first 7 turns of dialogue content | Urban gas policy consultations mostly involve 3 to 5 consecutive questions. Retaining 7 turns covers complete consultation flows and filters redundant information |
| Question optimization | Calibrate based on actual testing | Adapt to keyword differences across local policies, automatically adjust retrieval terminology, and improve retrieval accuracy of policy clauses |
Three common configuration errors
- Symptom: User identifiers linked to the
chatIdparameter are not displayed in conversation logs, and multi-turn dialogue context is lost. Cause: ThechatIdparameter was not passed correctly during API calls, or context binding was not enabled in the dialogue configuration. - Symptom: Background logs are deleted synchronously when a conversation initiated via a guest link is deleted. Cause: No log retention rules were configured for guest conversations, and the default deletion logic applies to user operations.
- Symptom: Policy clauses returned by tool calls are not correctly carried over to the next dialogue turn. Cause: Tool results were not injected into the dialogue context via the
variablesconfiguration, causing subsequent questions to fail to reference already obtained policy content.
How to verify successful configuration
- Initiate two consecutive policy consultation requests, check for valid
chatIdparameter records in the conversation logs, and confirm the context link is functional. - Initiate a conversation via a guest link and delete it, check if the conversation’s operation record is retained in the background logs, and confirm log retention rules are configured correctly.
- Initiate a consultation that includes local region and scenario details, check if the returned policy content matches the rules of the corresponding province or city, and confirm the
variablesconfiguration is active. - Call a tool to retrieve policy clauses, then initiate a subsequent related question, check if the returned content includes the previous round’s tool results, and confirm context injection is working properly.
