What Data for This Category Looks Like
The policy and regulatory basis data for urban investment platforms mainly comes from publicly available normative documents issued by the National Development and Reform Commission, Ministry of Housing and Urban-Rural Development, local state-owned assets supervision and administration commissions, and local governments. It also includes internal compliance management systems of urban investment platforms. Data updates have no fixed cycle, and are synchronized when new policies are issued or existing systems are revised. Most documents are in PDF or Word format, with varying single-document lengths. Fields include policy document number, issuing authority, effective date, applicable hierarchy, and full text of core clauses. There are no dedicated special unit requirements.
Constraints on Citation Sources and Traceability
The policy data sources for urban investment platforms are scattered, covering multiple levels including national, provincial, municipal and local jurisdictions. This means the traceability link needs to match multi-dimensional classification tags to avoid confusion between cross-level policies. There is no fixed update cycle, so the traceability function must support real-time verification of data timeliness to prevent the use of expired or revised policy texts. The varying document lengths require that splitting rules balance clause integrity, and must not split core compliance clauses. Fields such as policy document number and effective date require precise association of corresponding clauses during traceability to ensure that the cited content matches the Q&A scenario.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | The length of core clauses in single urban investment policy documents is concentrated in this range, to avoid truncation of key compliance content |
responseData | Structured format with traceability information | It is necessary to clearly associate the policy document number and specific clause location to meet compliance traceability requirements |
detail | Enabled | Urban investment policy Q&A requires displaying full details of clause texts to facilitate direct verification of cited content |
| Single recall limit | Top 3 entries | Urban investment compliance policies mostly come from a small number of documents with clear hierarchies; excessive recall will interfere with core citation logic |
| Data update verification cycle | 7 days | Adapts to the regular update rhythm of urban investment policies, ensuring cited content is always the latest valid version |
Three Common Misconfigurations
- Garbled characters appear in the citation content displayed on the interface. This is mostly caused by parsing errors when the uploaded policy document does not specify the correct encoding format. Urban investment platform policy documents may contain local special symbols or dialect expressions, and failing to specify the encoding during upload will trigger parsing exceptions.
- Only partial policy clauses are returned in the answer, with core content truncated. This is caused by an incorrectly set
quoteMaxTokenparameter, where the value is smaller than the actual length of the target policy clause. - No citation sources are displayed in the Q&A results, only plain text answers are returned. This is caused by not enabling the traceability configuration corresponding to
responseData, and not turning on the structured output mode.
How to Confirm Successful Configuration
- Initiate a Q&A targeting specific policy clauses, and check whether the answer includes traceability information such as policy document number and clause location.
- Check the length of the cited content in the answer, confirm that core clauses are not truncated, and adjust the corresponding configuration items to a suitable range.
- Upload a test policy document, verify that complete field information is retained after parsing, with no garbled characters or missing content.
- Simulate a call to the corresponding Q&A API, check whether the returned data includes preset traceability-related fields.
