What the data for this category looks like
Data for urban gas policy and regulatory basis is primarily sourced from official public documents issued by the Ministry of Housing and Urban-Rural Development and urban and provincial gas management offices. Updates to new industry specifications occur every quarter, and local implementation rules are updated annually. Documents are stored in standard official document format, including fields such as document number, issuing authority, effective date, clause number, applicable region, and specific requirements. Specialized gas industry measurement and specification units such as MPa, cubic meters, and hours are used across these documents.
What constraints do these characteristics impose on source citation and traceability
The unique characteristics of urban gas policy data create clear constraints for the source citation and traceability process. The official document-style clause number field requires traceability to accurately locate specific clauses, and fuzzy paragraph matching is not allowed. The applicable region field requires recall operations to filter matching local implementation rules based on the user’s city. The high-frequency update feature requires the knowledge base synchronization cycle to not exceed one quarter, to prevent referencing expired clauses. Specialized measurement units require recall results to retain original units, with no arbitrary conversion permitted.
How to configure settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 800–1200 token | Matches the average length of a single urban gas policy clause, to avoid truncating key specification content |
responseData | Enable original text citation | Retains traceability-required information from policy original texts, such as document numbers and clause numbers |
detail | Enable detailed traceability | Displays the issuing authority and effective date of cited clauses, to meet industry compliance requirements |
| Single recall limit | Top 3 entries | Core specifications for urban gas policies in a single scenario do not exceed 3 entries, to avoid information overload |
| Knowledge base synchronization cycle | Every quarter | Aligns with the industry specification update frequency, to ensure the timeliness of referenced content |
| Knowledge base storage limit | 1000 MB | Adapts to the total storage scale of urban gas policy documents, to avoid overflow |
Three common configuration mistakes
- Symptom: Garbled characters appear in returned citation content. Cause: The encoding format during knowledge base upload is not correctly configured. Most urban gas policy documents use GBK or traditional Chinese encoding. Failure to convert to UTF-8 causes parsing exceptions.
- Symptom: The cited thought process has messy formatting and contains a large number of redundant official document markers. Cause: The
detailconfiguration is not enabled, causing the model to directly splice original chunked text without extracting a standardized citation format. - Symptom: Recalled cited clauses do not match the user’s city. Cause: No recall rule for filtering by applicable region is configured, leading to incorrect referencing of cross-regional policies.
How to confirm configurations are properly set
- Upload a local urban gas policy document, and check if the chunked content parsed by the knowledge base retains key fields such as document number and clause number.
- Submit a question related to gas policies, and verify if the returned results include the issuing authority and effective date of the citation source.
- Simulate a corresponding interface call, and confirm that the returned
responseDatafield contains complete original text citation content. - Wait one quarter, and check if the knowledge base has automatically synchronized the latest industry specification documents.
