What the data for this category looks like
Official public documents from the Ministry of Housing and Urban-Rural Development, provincial housing and urban-rural development departments, and local housing authorities are the primary source of policy and regulatory basis data for the survey and design field. Data update schedules align with policy releases. The knowledge base syncs within 1 to 3 business days after a new policy is issued.
Documents follow the standard official red-headed document format, and include core fields such as document number, issuing authority, effective date, chapters and clauses. Individual document lengths range from hundreds to tens of thousands of words. Some industry standard documents include technical parameters, calculation standards and other detailed content.
Constraints on citation sources and traceability
The long text nature of survey and design policy documents requires the citation traceability process to support full reading of individual core clauses. This avoids truncating critical supporting basis.
Multiple source policies may have conflicts between old and new versions. Traceability must clearly mark the effective time and document number of each file. This ensures the timeliness and accuracy of citations.
Data fields include two types of content: technical parameters and administrative clauses. These must be accurately distinguished, and corresponding metadata extracted. This prevents confusion of traceability information.
Frequently updated policies require timely knowledge base synchronization mechanisms. Otherwise, citations of outdated, expired documents may occur.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 8000–12000 token | Core clauses of individual survey and design policy documents are mostly thousands of words long. This range fully covers commonly used citation scopes |
responseData | Enable direct original text return | Meets user needs for directly outputting knowledge base original text without modification, ensuring the originality of traceability content |
detail | Enable display of document number and effective date | Extracts fields such as document number and release time, enhancing the credibility and traceability of traceability information |
| Multiple knowledge base associations | Bind no more than 3 policy-related knowledge bases | Adapts to query needs for multi-level policies in the survey and design field, avoiding recall of irrelevant content |
| Context window | 15000–20000 token | Offsets delays in large model processing of long texts, adapting to long-context retrieval scenarios for policy documents |

Three Common Configuration Mistakes
- Phenomenon: AI responses only include content rewritten by the large model, and do not attach the knowledge base original text. Cause: The original text return setting corresponding to
responseDatais not enabled. The system uses summary content generated by the large model by default. - Phenomenon: A single query only returns results from a single policy document, and cannot cover multi-dimensional policy basis. Cause: Multiple knowledge base associations are not configured, and only a single policy knowledge base is bound.
- Phenomenon: Retrieval requests time out, or returned content is forcibly truncated. Cause: The
quoteMaxTokensetting exceeds the system processing limit, causing the request to fail to complete normally.
How to Confirm Correct Configuration
- Launch a query that includes a specific policy document number. Check if the reply includes the corresponding document number and effective date at the end.
- Compare the reply content with the knowledge base original text. Confirm that no additional rewriting or polishing is present, and only the original text content is retained.
- Launch a query for cross-departmental policies. Verify that returned results come from both the Ministry of Housing and Urban-Rural Development and local housing and urban-rural development department knowledge bases.
- Adjust the
quoteMaxTokenparameter. Observe whether the length of returned content changes correspondingly with the configuration.
