What this category of data looks like
The policy and regulatory basis data for building construction general contracting comes primarily from official documents released by the Ministry of Housing and Urban-Rural Development, provincial housing and urban-rural development authorities, and standardized guidelines from industry organizations such as the China Construction Industry Association. Data updates are synchronized with new national and local housing and urban-rural development policies, with no fixed cycle. The document structure includes fixed fields such as policy document number, issuing authority, effective date, core clauses, and applicable project scope. Field formats follow official document standards, with no custom special units.
What constraints these characteristics impose on the "multi-turn dialogue and prompt engineering" link
The fixed format of official documents requires that multi-turn dialogue accurately match policy document numbers and corresponding clauses to avoid vague or incorrect statements. Since data updates have no fixed cycle, multi-turn dialogue must support rapid recall of the latest policies to avoid referencing expired clauses. The structured document fields require prompts to guide extraction of key information such as issuing authority and effective date to ensure compliance of responses. Additionally, building construction policies often involve differences in local detailed regulations. Multi-turn dialogue must support users supplementing regional information to narrow retrieval scope and avoid confusion between cross-regional policies.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Conversation context window | Previous 10 historical messages | Building construction policy Q&A often requires tracing pre-conversation information such as region and project type from multi-turn follow-ups. Retaining 10 messages covers complete dialogue logic |
messages parameter | Truncated to 8000 characters | Building construction policy documents have relatively long length. Truncating overly long contexts avoids exceeding model processing limits, and complies with parameter specifications of FastGPT v4.17.0 |
| Citation display setting | Enable citation display by default | Policy Q&A requires clear source references to meet compliance requirements in the engineering field |
| Quick question configuration | Preset 3 high-frequency policy questions | Adapts to the quick query habits of engineering personnel and lowers input barriers |
| Context recall limit | Top 8 matching documents | Building construction policy clauses are densely packed. Excessive recall leads to information redundancy; 8 documents cover core basis |
| File upload format restriction | Only PDF format allowed | Building construction policies are mostly released as PDF official documents. Unified format improves parsing accuracy |
Three common errors
- Issue: Citation content is forcibly displayed at the end of dialogue responses, and the prompt "No permission to operate this conversation record" appears in some scenarios. Cause: The global citation display switch was not turned off, and exemption rules for conversation record permissions were not configured.
- Issue: Clicking the quick buttons in the dialogue opening screen sends no content. Cause: Preset questions were not bound to the dialogue sending logic, and initialization content for the
chatIdparameter was not correctly associated. - Issue: Uploaded policy files cannot be received when calling the dialogue API. Cause: The file upload whitelist for the dialogue API was not configured, or allowed file formats were not specified.
How to confirm configurations are set correctly
- Launch a multi-turn dialogue that includes region and project type, and check if returned results accurately link to corresponding policy clauses.
- Enter the dialogue settings interface, adjust the citation display switch, and verify if responses show or hide citation content as configured.
- Click the preset quick question button, and confirm that the corresponding question is automatically filled in the dialogue box and can be sent directly.
- Call the dialogue API, pass the
chatIdparameter, and verify that previous dialogue content is correctly retained in context history.
The values listed above are common starting points and should be validated against specific operational samples.
